CHAPTER 1.7
General requirements concerning Class 7
1.7.1. General
1.7.1.1. This Directive establishes standards of safety which provide an acceptable level of control of the radiation, criticality and thermal hazards to persons, property and the environment that are associated with the carriage of radioactive material. These standards are based on the IAEA Regulations for the Safe Transport of Radioactive Material (ST-1), IAEA, Vienna (1996). Explanatory material on ST-1 can be found in "Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material (1996 Edition)", Safety Standard Series No ST-2, IAEA, Vienna (to be published).
1.7.1.2. The objective of this Directive is to protect persons, property and the environment from the effects of radiation during the transport of radioactive material. This protection is achieved by requiring:
(a) Containment of the radioactive contents;
(b) Control of external radiation levels;
(c) Prevention of criticality; and
(d) Prevention of damage caused by heat.
These requirements are satisfied firstly by applying a graded approach to contents limits for packages and wagons and to performance standards applied to package designs depending upon the hazard of the radioactive contents. Secondly, they are satisfied by imposing requirements on the design and operation of packages and on the maintenance of packagings, including a consideration of the nature of the radioactive contents. Finally, they are satisfied by requiring administrative controls including, where appropriate, approval by competent authorities.
1.7.1.3. This Directive applies to the transport of radioactive material by rail including transport which is incidental to the use of the radioactive material. Transport comprises all operations and conditions associated with and involved in the movement of radioactive material; these include the design, manufacture, maintenance and repair of packaging, and the preparation, consigning, loading, carriage including in-transit storage, unloading and receipt at the final destination of loads of radioactive material and packages. A graded approach is applied to the performance standards in this Directive that is characterized by three general severity levels:
(a) Routine conditions of transport (incident free);
(b) Normal conditions of transport (minor mishaps);
(c) Accident conditions of transport.
1.7.2. Radiation protection programme
1.7.2.1. The transport of radioactive material shall be subject to a Radiation Protection Programme which shall consist of systematic arrangements aimed at providing adequate consideration of radiation protection measures.
1.7.2.2. The nature and extent of the measures to be employed in the programme shall be related to the magnitude and likelihood of radiation exposures. The programme shall incorporate the requirements in 1.7.2.3, and 1.7.2.4, CV33 (1.1) and (1.4) of 7.5.11 and applicable emergency response procedures. Programme documents shall be available, on request, for inspection by the relevant competent authority.
1.7.2.3. Protection and safety shall be optimised in order that the magnitude of individual doses, the number of persons exposed, and the likelihood of incurring exposure shall be kept as low as reasonably achievable, economic and social factors being taken into account, and doses to persons shall be below the relevant dose limits. A structured and systematic approach shall be adopted and shall include consideration of the interfaces between transport and other activities.
1.7.2.4. For occupational exposures arising from transport activities, where it is assessed that the effective dose:
(a) is most unlikely to exceed 1 mSv in a year, no special work patterns, detailed monitoring, dose assessment programmes or individual record keeping shall be required;
(b) is likely to be between 1 mSv and 6 mSv in a year, a dose assessment programme via work place monitoring or individual monitoring shall be conducted;
(c) is likely to exceed 6 mSv in a year, individual monitoring shall be conducted.
When individual monitoring or work place monitoring is conducted, appropriate records shall be kept.
1.7.3. Quality assurance
Quality assurance programmes based on international, national or other standards acceptable to the competent authority shall be established and implemented for the design, manufacture, testing, documentation, use, maintenance and inspection of all special form radioactive material, low dispersible radioactive material and packages and for transport and in-transit storage operations to ensure compliance with the relevant requirements of this Directive. Certification that the design specification has been fully implemented shall be available to the competent authority. The manufacturer, consignor or user shall be prepared to provide facilities for competent authority inspection during manufacture and use and to demonstrate to any cognizant competent authority that:
(a) the manufacturing methods and materials used are in accordance with the approved design specifications; and
(b) all packagings are periodically inspected and, as necessary, repaired and maintained in good condition so that they continue to comply with all relevant requirements and specifications, even after repeated use.
Where competent authority approval is required, such approval shall take into account and be contingent upon the adequacy of the quality assurance programme.
1.7.4. Special arrangement
1.7.4.1. Special arrangement shall mean those requirements, approved by the competent authority, according to which consignments which do not satisfy all the requirements of this Directive applicable to radioactive material may be carried.
NOTE
Special arrangement is not considered to be a temporary derogation in accordance with 1.5.1.
1.7.4.2. Consignments for which conformity with any requirement applicable to Class 7 is impracticable shall not be carried except under special arrangement. Provided the competent authority is satisfied that conformity with the Class 7 requirements of this Directive is impracticable and that the requisite standards of safety established by this Directive have been demonstrated through alternative means the competent authority may approve special arrangement transport operations for single or a planned series of multiple consignments. The overall level of safety in transport shall be at least equivalent to that which would be provided if all the applicable requirements had been met. For international consignments of this type, multilateral approval shall be required.
1.7.5. Radioactive material possessing other dangerous properties
In addition to the radioactive and fissile properties, any subsidiary risk of the contents of the package, such as explosiveness, flammability, pyrophoricity, chemical toxicity and corrosiveness, shall also be taken into account in the packing, labelling, marking, placarding, stowage, separation and carriage, in order to be in compliance with all the relevant requirements of this Directive.
CHAPTER 1.8
Checks and other support measures to ensure compliance with safety requirements
1.8.1. Administrative controls of dangerous goods
1.8.1.1. The competent authorities of the Member States may, on their national territory, at any time, conduct spot checks to verify whether the requirements concerning the carriage of dangerous goods have been met.
These checks shall, however, be made without endangering persons, property or the environment and without major disruption of rail services.
1.8.1.2. Participants in the carriage of dangerous goods (Chapter 1.4) shall, without delay, in the context of their respective obligations, provide the competent authorities and their agents with the necessary information for carrying out the checks.
1.8.1.3. The competent authorities may also, for the purposes of carrying out checks on the premises of the enterprises participating in the carriage of dangerous goods (Chapter 1.4), make inspections, consult the necessary documents and remove samples of dangerous goods or packagings for examination, provided that safety is not jeopardized thereby. The participants in the carriage of dangerous goods (Chapter 1.4) shall also make the wagons or parts of wagons and the equipment and installations accessible for the purpose of checking where this is possible and reasonable. They may, if they deem necessary, designate a person from the enterprise to accompany the representative of the competent authority.
1.8.1.4. If the competent authorities observe that the requirements of this Directive have not been met, they may prohibit a consignment or interrupt a transport operation until the defects observed are rectified, or they may prescribe other appropriate measures. Immobilization may take place on the spot or at another place selected by the authorities for safety reasons. These measures shall not cause a major disruption in rail services.
1.8.2. Mutual administrative support
1.8.2.1. The Member States shall agree on mutual administrative support for the implementation of this Directive.
1.8.2.2. When a Member State has reasons to observe that the safety of the carriage of dangerous goods on its territory is compromised as a result of very serious or repeated infringements by an enterprise which has its headquarters on the territory of another Member State, it shall notify the competent authorities of this Member State of such infringements. The competent authorities of the Member State on the territory of which the very serious or repeated infringements were observed may request the competent authorities of the Member State on the territory of which the enterprise has its headquarters to take appropriate measures against the offender(s). The transmission of data referring to persons shall not be permitted unless it is necessary for the prosecution of very serious or repeated infringements.

UN No 1325 FLAMMABLE SOLID, ORGANIC, N.O.S.
UN No 1993 FLAMMABLE LIQUID, N.O.S.
The entries defined under B, C and D are defined as collective entries.
2.1.1.3. For packing purposes, certain substances may be assigned to packing groups in accordance with their degree of danger. The packing groups have the following meanings:
Packing group I: Substances presenting high danger
Packing group II: Substances presenting medium danger
Packing group III: Substances presenting low danger
2.1.2. Principles of classification
2.1.2.1. The dangerous goods covered by the heading of a class are defined on the basis of their properties according to sub-section 2.2.x.1 of the relevant class. Assignment of dangerous goods to a class and a packing group is made according to the criteria mentioned in the same sub-section 2.2.x.1. Assignment of one or several subsidiary risk(s) to a dangerous substance or article is made according to the criteria of the class or classes corresponding to those risks, as mentioned in the appropriate sub-section(s) 2.2.x.1.
2.1.2.2. All dangerous goods entries are listed in table A of Chapter 3.2 in the numerical order of their UN Number. This table contains relevant information on the goods listed, such as name, class, packing group(s), label(s) to be affixed, packing and carriage requirements.
NOTE:
An alphabetical list of these entries is given in table B of Chapter 3.2.
2.1.2.3. Dangerous goods which are listed or defined in sub-section 2.2.x.2 of each class are not to be accepted for carriage.
2.1.2.4. Goods not mentioned by name, i.e. goods not listed as single entries in table A of Chapter 3.2 and not listed or defined in one of the above-mentioned sub-sections 2.2.x.2 shall be assigned to the relevant class in accordance with the procedure in 2.1.3. In addition, the subsidiary risk (if any) and the packing group (if any) shall be determined. Once the class, subsidiary risk (if any) and packing group (if any) have been established the relevant UN number shall be determined. The decision trees in sub-sections 2.2.x.3 (list of collective entries) at the end of each class indicate the relevant parameters for selecting the relevant collective entry (UN number). In all cases the most specific collective entry covering the properties of the substance or article shall be selected, according to the hierarchy indicated in 2.1.1.2 by the letters B, C and D respectively. If the substance or article cannot be classified under entries of type B or C according to 2.1.1.2, then, and only then shall it be classified under an entry of type D.
2.1.2.5. On the basis of the test procedures of Chapter 2.3 and the criteria set out in sub-sections 2.2.x.1 of classes when it is so specified, it may be determined that a substance, solution or mixture of a certain class, mentioned by name in Table A of Chapter 3.2, does not meet the criteria of that class. In such a case, the substance, solution or mixture is deemed not to belong to that class.
2.1.2.6. For the purposes of classification, substances with a melting point or initial melting point of 20 °C or lower at a pressure of 101,3 kPa shall be considered to be liquids. A viscous substance for which a specific melting point cannot be determined shall be subjected to the ASTM D 4359-90 test or to the test for determining fluidity (penetrometer test) prescribed in 2.3.4.
2.1.3. Classification of substances, including solutions and mixtures (such as preparations and wastes), not mentioned by name
2.1.3.1. Substances, including solutions and mixtures, not mentioned by name shall be classified according to their degree of danger on the basis of the criteria mentioned in sub-section 2.2.x.1 of the various classes. The danger(s) presented by a substance shall be determined on the basis of its physical and chemical characteristics and physiological properties. Such characteristics and properties shall also be taken into account when such experience leads to a more stringent assignment.
2.1.3.2. A substance not mentioned by name in table A of Chapter 3.2 presenting a single hazard shall be classified in the relevant class under a collective entry listed in sub-section 2.2.x.3 of that class.
2.1.3.3. A solution or mixture containing only one dangerous substance mentioned by name in table A of Chapter 3.2, together with one or more non-dangerous substance(s), shall be regarded as the dangerous substance listed by name, unless:
(a) the solution or mixture is specifically mentioned by name in table A of Chapter 3.2; or
(b) it is quite clear from the entry for the dangerous substance that it is applicable only to the pure or technically pure substance; or
(c) the class, physical state or packing group of the solution or mixture is different from that of the dangerous substance.
In the case of (b) or (c), the solution or mixture shall be classified as a substance mentioned by name in the relevant class under a collective entry according to sub-section 2.2.x.3 of that class, taking account of any subsidiary risks, unless the substance or mixture does not meet the criteria of a particular class and is not therefore subject to the requirements of this Directive.
2.1.3.4. Solutions and mixtures containing one of the following substances mentioned by name shall always be classified under the same entry as the substance they contain, provided they do not have the hazard characteristics as indicated in 2.1.3.5:
- Class 3
UN No 1921 PROPYLENEIMINE, INHIBITED;

(i) Infectious substances of Class 6.2.
2.1.3.5.4. If the hazard characteristics of the substance fall within more than one class or group of substances not listed in 2.1.3.5.3 above, the substance shall be classified in accordance with the same procedure but the relevant class shall be selected according to the precedence of hazards table in 2.1.3.9.
2.1.3.6. The most specific applicable generic entry (see 2.1.2.4) shall always be used, i.e. a general n.o.s. entry shall only be used if a generic entry or a specific n.o.s. entry cannot be used.
2.1.3.7. Solutions and mixtures of oxidizing substances or substances with an oxidizing subsidiary risk may have explosive properties. In such a case they are not to be accepted for carriage unless they meet the requirements for Class 1.
2.1.3.8. For the purposes of this Directive, substances, solutions and mixtures (such as preparations and wastes) which cannot be assigned to Classes 1 to 8 or Class 9 entries other than UN Nos 3077 and 3082, but which may be assigned to UN Nos 3077 or 3082 on the basis of the test methods and criteria of section 2.3.5 shall be considered to be pollutant to the aquatic environment. Solutions and mixtures (such as preparations and wastes) for which no data conforming to the classification criteria are available shall be considered to be pollutant to the aquatic environment if the LC50 (see definitions in 2.3.5.1, 2.3.5.2 and 2.3.5.3) evaluated according to the following formula:

2.2.1.1.1. The heading of Class 1 covers:
(a) Explosive substances: solid or liquid substances (or mixtures of substances) capable by chemical reaction of producing gases at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
Pyrotechnic substances: substances or mixtures of substances designed to produce an effect by heat, light, sound, gas or smoke or a combination of these as the result of non-detonating self-sustaining exothermic chemical reactions.
NOTES:
1. Substances which are not themselves explosive but which may form an explosive mixture of gas, vapour or dust are not substances of Class 1.
2. Also excluded from Class 1 are: water- or alcohol-wetted explosives of which the water or alcohol content exceeds the limits specified and those containing plasticizers - these explosives are assigned to Class 3 or Class 4.1 - and those explosives which, on the basis of their predominant hazard, are assigned to Class 5.2.
(b) Explosive articles: articles containing one or more explosive substances or pyrotechnic substances.
NOTE:
Devices containing explosive or pyrotechnic substances in such small quantity or of such a character that their inadvertent or accidental ignition or initiation during carriage would not cause any manifestation external to the device by projection, fire, smoke, heat or loud noise are not subject to the requirements of Class 1.
(c) Substances and articles not mentioned above which are manufactured with a view to producing a practical effect by explosion or a pyrotechnic effect.
2.2.1.1.2. Any substance or article having or suspected of having explosive properties shall be considered for assignment to Class 1 in accordance with the tests, procedures and criteria prescribed in Part I, Manual of Tests and Criteria.
A substance or article assigned to Class 1 can only be accepted for carriage when it has been assigned to a name or n.o.s. entry listed in table A of Chapter 3.2 and meets the criteria of the Manual of Tests and Criteria.
2.2.1.1.3. The substances and articles of Class 1 shall be assigned to a UN Number and a name or n.o.s. entry listed in table A of Chapter 3.2. Interpretation of the names of substances and articles in table A of Chapter 3.2 shall be based upon the glossary in 2.2.1.1.7.
Samples of new or existing explosive substances or articles carried for purposes including: testing, classification, research and development quality control, or as a commercial sample, other than initiating explosive, may be assigned to UN No 0190 SAMPLES, EXPLOSIVE.
The assignment of substances and articles not mentioned by name as such in table A of Chapter 3.2 to an n.o.s. entry or UN No 0190 SAMPLES, EXPLOSIVE as well as the assignment of certain substances the carriage of which is subject to a specific authorization by the competent authority according to the special requirements referred to in column (6) of table A of Chapter 3.2 shall be made by the competent authority of the country of origin. This competent authority shall also approve in writing the conditions of carriage of these substances and articles. If the country of origin is not a COTIF Member State, the classification and the conditions of carriage shall be recognized by the competent authority of the first COTIF Member State reached by the consignment.
2.2.1.1.4. Substances and articles of Class 1 shall be assigned to a division in accordance with 2.2.1.1.5 and to a compatibility group in accordance with 2.2.1.1.6. The division shall be based on the results of the tests described in section 2.3.0 and 2.3.1 applying the definitions in 2.2.1.1.5. The compatibility group shall be determined in accordance with the definitions in 2.2.1.1.6. The classification code shall consist of the division number and the compatibility group letter.
2.2.1.1.5. Definition of divisions
>TABLE>
NOTE:
The risk from articles of Division 1.6 is limited to the explosion of a single article.
2.2.1.1.6. Definition of compatibility groups of substances and articles
>TABLE>
NOTES:
1. Each substance or article, packed in a specified packaging, may be assigned to one compatibility group only. Since the criterion of compatibility group S is empirical, assignment to this group is necessarily linked to the tests for assignment of a classification code.
2. Articles of compatibility groups D and E may be fitted or packed together with their own means of initiation provided that such means have at least two effective protective features designed to prevent an explosion in the event of accidental functioning of the means of initiation. Such packages shall be assigned to compatibility groups D or E.
3. Articles of compatibility groups D and E may be packed together with their own means of initiation, which do not have two effective protective features (i.e. means of initiation assigned to compatibility group B), provided that they comply with mixed packing provision MP 21 of section 4.1.10. Such packages shall be assigned to compatibility groups D or E.
4. Articles may be fitted or packed together with their own means of ignition provided that the means of ignition cannot function during normal conditions of carriage.
5. Articles of compatibility groups C, D and E may be packed together. Such packages shall be assigned to compatibility group E.
2.2.1.1.7. Glossary of names
NOTES:
1. The descriptions in the glossary are not intended to replace the test procedures, nor to determine the hazard classification of a substance or article of Class 1. Assignment to the correct division and a decision on whether Compatibility Group S is appropriate shall be based on testing of the product in accordance with the Manual of Tests and Criteria, Part I or by analogy with similar products which have already been tested and assigned in accordance with the procedures of the Manual of Tests and Criteria.

For gases and gas mixtures presenting hazardous properties associated with more than one group according to the criteria, the groups designated by letter T take precedence over all other groups. The groups designated by letter F take precedence over the groups designated by letters A or O.
NOTES:
1. In the UN Model Regulations, the IMDG Code and the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air, gases are assigned to one of the following three divisions, based on the primary hazard:
Division 2.1: flammable gases (corresponding to the groups designated by the capital letter F);
Division 2.2: non-flammable, non-toxic gases (corresponding to the groups designated by the capital letters A or O);
Division 2.3: toxic gases (corresponding to the groups designated by the capital letter T (i.e. T, TF, TC, TO, TFC and TOC).
2. Aerosols and receptacles, small, containing gas shall be assigned, according to the hazard of the contents, to the letters A to TOC. The contents are considered to be flammable if they include more than 45 % by mass, or more than 250 g, of flammable components. Flammable components are gases which are flammable in air at normal pressure or substances or preparations in liquid form which have a flash-point less than or equal to 100 °C.
3. Corrosive gases are considered to be toxic, and are therefore assigned to the group TC, TFC or TOC.
4. Mixtures containing more than 21 % oxygen by volume shall be classified as oxidizing.
2.2.2.1.4. If a mixture of Class 2 mentioned by name in table A of Chapter 3.2 meets different criteria as mentioned in 2.2.2.1.2 and 2.2.2.1.5, this mixture shall be classified according to the criteria and assigned to an appropriate N.O.S. entry.
2.2.2.1.5. Substances and articles of Class 2 which are not mentioned by name in table A of Chapter 3.2 shall be classified under a collective entry listed in 2.2.2.3 in accordance with 2.2.2.1.2 and 2.2.2.1.3. The following criteria shall apply:
Asphyxiant gases
Gases which are non-oxidizing, non-flammable and non-toxic and which dilute or replace oxygen normally in the atmosphere.
Flammable gases
Gases which at 20 °C and a standard pressure of 101,3 kPa:
(a) are ignitable when in a mixture of 13 % or less by volume with air; or
(b) have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit.
Flammability shall be determined by tests or by calculation, in accordance with methods adopted by ISO (see ISO 10156:1996).
Where insufficient data are available to use these methods, tests by a comparable method recognized by the competent authority of the country of origin may be used.
If the country of origin is not a COTIF Member State these methods shall be recognized by the competent authority of the first COTIF Member State reached by the consignment.
Oxidizing gases
Gases, which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does. Oxidizing ability is determined either by tests or by calculation methods adopted by ISO (see ISO 10156:1996).
Toxic gases
NOTE:
Gases meeting the criteria for toxicity in part or completely owing to their corrosivity are to be classified as toxic. See also the criteria under the heading "Corrosive gases" for a possible subsidiary corrosivity risk.
Gases which:
(a) are known to be so toxic or corrosive to humans as to pose a hazard to health; or
(b) are presumed to be toxic or corrosive to humans because they have a LC50 value for acute toxicity equal to or less than 5000 ml/m3 (ppm) when tested in accordance with 2.2.61.1.
In the case of gas mixtures (including vapours of substances from other classes) the following formula may be used:
>PIC FILE= "L_2004121EN.006101.TIF">
where
fi= mole fraction of the ith component substance of the mixture;
Ti= toxicity index of the ith component substance of the mixture;
The Ti equals the LC50 value as found in ISO 10298:1995.
When no LC50 value is listed in ISO 10298:1995, a LC50 value available in scientific literature shall be used.
When the LC50 value is unknown, the toxicity index is determined by using the lowest LC50 value of substances of similar physiological and chemical effects, or through testing if this is the only practical possibility.
Corrosive gases
Gases or gas mixtures meeting the criteria for toxicity completely owing to their corrosivity shall be classified as toxic with a subsidiary corrosivity risk.
A gas mixture that is considered to be toxic due to the combined effects of corrosivity and toxicity has a subsidiary risk of corrosivity when the mixture is known by human experience to be destructive to the skin, eyes or mucous membranes or when the LC50 value of the corrosive components of the mixture is equal to or less than 5000 ml/m3 (ppm) when the LC50 is calculated by the formula:
>PIC FILE= "L_2004121EN.006102.TIF">
where
fci= mole fraction of the ith corrosive component substance of the mixture;
Tci= toxicity index of the ith corrosive component substance of the mixture;
The Tci equals the LC50 value as found in ISO10298:1995.
When no LC50 value is listed in ISO 10298:1995, a LC50 value available in scientific literature shall be used.
When the LC50 value is unknown the toxicity index is determined by using the lowest LC50 value of substances of similar physiological and chemical effects, or through testing if this is the only practical possibility.

2.2.41 Class 4.1 Flammable solids, self-reactive substances and solid desensitized explosives
2.2.41.1. Criteria
2.2.41.1.1. The heading of Class 4.1 covers flammable substances and articles, desensitized explosives which are solids according to subparagraph (a) of the definition "solid" in 1.2.1 and selfreactive solids or liquids.
The following are assigned to Class 4.1:
- readily flammable solid substances and articles (see 2.2.41.1.3 to 2.2.41.1.8);
- self-reactive solids or liquids (see 2.2.41.1.9 to 2.2.41.1.16);
- solid desensitized explosives (see 2.2.41.1.18);
- substances related to self-reactive substances (see 2.2.41.1.19).
2.2.41.1.2. The substances and articles of Class 4.1 are subdivided as follows:
>TABLE>
Flammable solids
Definition and properties
2.2.41.1.3. Flammable solids are readily combustible solids and solids which may cause fire through friction.
Readily combustible solids are powdered, granular, or pasty substances which are dangerous if they can be easily ignited by brief contact with an ignition source, such as a burning match, and if the flame spreads rapidly. The danger may come not only from the fire but also from toxic combustion products. Metal powders are especially dangerous because of the difficulty of extinguishing a fire since normal extinguishing agents such as carbon dioxide or water can increase the hazard.
Classification
2.2.41.1.4. Substances and articles classified as flammable solids of Class 4.1 are listed in table A of Chapter 3.2. The assignment of organic substances and articles not mentioned by name in table A of Chapter 3.2 to the relevant entry of sub-section 2.2.41.3 in accordance with the requirements of Chapter 2.1 can be based on experience or on the results of the test procedures in accordance with Part III, sub-section 33.2.1 of the Manual of Tests and Criteria. The assignment of inorganic substances not mentioned by name shall be based on the results of the test procedures in accordance with Part III, sub-section 33.2.1 of the Manual of Tests and Criteria; experience shall also be taken into account when it leads to a more stringent assignment.
2.2.41.1.5. When substances not mentioned by name are assigned to one of the entries listed in 2.2.41.3 on the basis of the test procedures in accordance with the Manual of Tests and Criteria, Part III, sub-section 33.2.1, the following criteria apply:
(a) With the exception of metal powders or powders of metal alloys, powdery, granular or pasty substances shall be classified as readily flammable substances of Class 4.1 if they can be easily ignited by brief contact with an ignition source (e.g. a burning match), or if, in the event of ignition, the flame spreads rapidly, the burning time is less than 45 seconds for a measured distance of 100 mm or the rate of burning is greater than 2,2 mm/s.
(b) Metal powders or powders of metal alloys shall be assigned to Class 4.1 if they can be ignited by a flame and the reaction spreads over the whole length of the sample in 10 minutes or less.
Solids which may cause fire through friction shall be classified in Class 4.1 by analogy with existing entries (e.g. matches) or in accordance with any appropriate special requirement.
2.2.41.1.6. On the basis of the test procedure in accordance with the Manual of Tests and Criteria, Part III, Section 33.2.1 and the criteria set out in 2.2.41.1.4 and 2.2.41.1.5, it may also be determined whether the nature of a substance mentioned by name is such that the substance is not subject to the requirements for this Class.
2.2.41.1.7. If substances of Class 4.1, as a result of admixtures, come into different categories of risk from those to which the substances mentioned by name in table A of Chapter 3.2 belong, these mixtures shall be assigned to the entries to which they belong on the basis of their actual degree of danger.
NOTE:
For the classification of solutions and mixtures (such as preparations and wastes) see also 2.1.3.
Assignment of packing groups
2.2.41.1.8. Flammable solids classified under the various entries in table A of Chapter 3.2 shall be assigned to packing groups II or III on the basis of test procedures of the Manual of Tests and Criteria, Part III, sub-section 33.2.1, in accordance with the following criteria:
(a) Readily flammable solids which, when tested, have a burning time of less than 45 seconds over a measured distance of 100 mm shall be assigned to:
Packing group II: if the flame passes the wetted zone;
Packing group III: if the wetted zone stops the flame for at least four minutes;
(b) Metal powders or powders of metal alloys shall be assigned to:
Packing group II: if, when tested, the reaction spreads over the whole length of the sample in five minutes or less;
Packing group III: if, when tested, the reaction spreads over the whole length of the sample in more than five minutes.
For solids which may cause fire through friction, the packing group shall be assigned by analogy with existing entries or in accordance with any special requirement.
Self-reactive substances
Definitions
2.2.41.1.9. For the purposes of this Directive, self-reactive substances are thermally unstable substances liable to undergo a strongly exothermic decomposition even without participation of oxygen (air). Substances are not considered to be self-reactive substances of Class 4.1, if:
(a) they are explosives according to the criteria of Class 1;
(b) they are oxidizing substances according to the assignment procedure of Class 5.1 (see 2.2.51.1);
(c) they are organic peroxides according to the criteria of Class 5.2 (see 2.2.52.1);
(d) their heat of decomposition is less than 300 J/g; or
(e) their self-accelerating decomposition temperature (SADT) (see Note 2 below) is greater than 75 °C for a 50 kg package.
NOTES:
1. The heat of decomposition can be determined using any internationally recognised method e.g. differential scanning calorimetry and adiabatic calorimetry.
2. The self-accelerating decomposition temperature (SADT) is the lowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used during carriage. Requirements for the determination of the SADT are given in the Manual of Tests and Criteria, Part II, Chapter 20 and section 28.4.
3. Any substance which shows the properties of a self-reactive substance shall be classified as such, even if this substance gives a positive test result according to 2.2.42.1.5 for classification in Class 4.2.
Properties
2.2.41.1.10. The decomposition of self-reactive substances can be initiated by heat, contact with catalytic impurities (e.g. acids, heavy-metal compounds, bases), friction or impact. The rate of decomposition increases with temperature and varies with the substance. Decomposition, particularly if no ignition occurs, may result in the evolution of toxic gases or vapours. For certain self-reactive substances, the temperature shall be controlled. Some self-reactive substances may decompose explosively, particularly if confined. This characteristic may be modified by the addition of diluents or by the use of appropriate packagings. Certain self-reactive substances burn vigorously. Self-reactive substances are, for example, some compounds of the types listed below:
- aliphatic azo compounds (-C-N=N-C-);
- organic azides (-C-N3);
- diazonium salts (-CN2+Z-);
- N-nitroso compounds (-N-N=O);
- aromatic sulphohydrazides (-SO2-NH-NH2).
This list is not exhaustive and substances with other reactive groups and some mixtures of substances may have similar properties.
Classification
2.2.41.1.11. Self-reactive substances are classified into seven types according to the degree of danger they present. The types of self-reactive substances range from type A, which is not accepted for carriage in the packaging in which it is tested, to type G, which is not subject to the requirements for self-reactive substances of Class 4.1. The classification of types B to F is directly related to the maximum quantity allowed in one packaging. The principles to be applied for classification as well as the applicable classification procedures, test methods and criteria and an example of a suitable test report are given in Part II of the Manual of Tests and Criteria.
2.2.41.1.12. Substances which have already been classified and assigned to the appropriate collective entry are listed in 2.2.41.4 together with the applicable UN number and packing method.
The collective entries specify:
- self-reactive substances types B to F, see 2.2.41.1.11 above;
- physical state (liquid/solid).
The classification of the self-reactive substances listed in 2.2.41.4 is based on the technically pure substance (except where a concentration of less than 100 % is specified).
2.2.41.1.13. Classification of self-reactive substances or formulations of self-reactive substances not listed in 2.2.41.4 and assignment to a collective entry shall be made by the competent authority of the country of origin on the basis of a test report. The statement of approval shall contain the classification and the relevant transport conditions. If the country of origin is not a COTIF Member State, the classification and the conditions of carriage shall be recognized by the competent authority of the first COTIF Member State reached by the consignment.
2.2.41.1.14. Activators, such as zinc compounds, may be added to some self-reactive substances to change their reactivity. Depending on both the type and the concentration of the activator, this may result in a decrease in thermal stability and a change in explosive properties. If either of these properties is altered, the new formulation shall be assessed in accordance with the classification procedure.
2.2.41.1.15. Samples of self-reactive substances or formulations of self-reactive substances not listed in 2.2.41.4, for which a complete set of test results is not available and which are to be carried for further testing or evaluation, shall be assigned to one of the appropriate entries for self-reactive substances type C provided the following conditions are met:
- the available data indicates that the sample would be no more dangerous than self-reactive substances type B;
- the sample is packaged in accordance with packing method OP2 and the quantity per wagon is limited to 10 kg;
Samples requiring temperature control shall not be accepted for carriage by rail.
Desensitization
2.2.41.1.16. In order to ensure safety during carriage, self-reactive substances are in many cases desensitized by use of a diluent. Where a percentage of a substance is stipulated, this refers to the percentage by mass, rounded to the nearest whole number. If a diluent is used, the self-reactive substance shall be tested with the diluent present in the concentration and form used in carriage. Diluents which may allow a self-reactive substance to concentrate to a dangerous extent in the event of leakage from a packaging shall not be used. Any diluent shall be compatible with the self-reactive substance. In this regard, compatible diluents are those solids or liquids which have no detrimental influence on the thermal stability and hazard type of the self-reactive substance.
2.2.41.1.17. (reserved)
Solid desensitized explosives
2.2.41.1.18. Solid desensitized explosives are substances which are wetted with water or alcohols or are diluted with other substances to suppress their explosive properties. Such entries in table A of Chapter 3.2 are: UN Nos 1310, 1320, 1321, 1322, 1336, 1337, 1344, 1347, 1348, 1349, 1354, 1355, 1356, 1357, 1517, 1571, 2555, 2556, 2557, 2852, 2907, 3317, 3319 and 3344; and, if special requirement 15 of Chapter 3.3 is complied with: UN Nos 0154, 0155, 0209, 0214, 0215 and 0234; and, if special requirement 18 of Chapter 3.3. is complied with: UN No 0220.
Substances related to self-reactive substances
2.2.41.1.19. Substances which
(a) were provisionally classified under Class 1 in accordance with test series 1 and 2, but which are exempted from Class 1 on the basis of test series 6;
(b) are not self-reactive substances of Class 4.1;
(c) are not substances of classes 5.1 or 5.2
are also classified under Class 4.1. Such entries are UN Nos 2956, 3241, 3242 and 3251.
2.2.41.2. Substances not accepted for carriage
2.2.41.2.1. The chemically unstable substances of Class 4.1 shall not be accepted for carriage unless the necessary steps have been taken to prevent their dangerous decomposition or polymerization during carriage. To this end, it shall in particular be ensured that receptacles and tanks do not contain any substance liable to promote these reactions.
2.2.41.2.2. Flammable solids, oxidizing, assigned to UN No 3097 shall not be accepted for carriage unless they meet the requirements for Class 1 (see also 2.1.3.7).

2.2.42 Class 4.2 Substances liable to spontaneous combustion
2.2.42.1. Criteria
2.2.42.1.1. The heading of Class 4.2 covers:
- Pyrophoric substances which are substances, including mixtures and solutions (liquid or solid), which even in small quantities ignite on contact with air within five minutes. These are the Class 4.2 substances the most liable to spontaneous combustion; and
- Self-heating substances and articles which are substances and articles, including mixtures and solutions, which, on contact with air, without energy supply, are liable to self-heating. These substances will ignite only in large amounts (kilogrammes) and after long periods of time (hours or days).
2.2.42.1.2. The substances and articles of Class 4.2 are subdivided as follows:
>TABLE>
Properties
2.2.42.1.3. Self-heating of these substances, leading to spontaneous combustion, is caused by reaction of the substance with oxygen (in the air) and the heat developed not being conducted away rapidly enough to the surroundings. Spontaneous combustion occurs when the rate of heat production exceeds the rate of heat loss and the auto-ignition temperature is reached.

2.2.52. Class 5.2 Organic peroxides
2.2.52.1. Criteria
2.2.52.1.1. The heading of Class 5.2 covers organic peroxides and formulations of organic peroxides.
2.2.52.1.2. The substances of Class 5.2 are subdivided as follows:
- P1 Organic peroxides, not temperature controlled;
- P2 Organic peroxides, temperature-controlled (not to be accepted for carriage).
Definition
2.2.52.1.3. Organic peroxides are organic substances which contain the bivalent -O-O- structure and may be considered derivatives of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals.
Properties
2.2.52.1.4. Organic peroxides are liable to exothermic decomposition at normal or elevated temperatures. The decomposition can be initiated by heat, contact with impurities (e.g. acids, heavy-metal compounds, amines), friction or impact. The rate of decomposition increases with temperature and varies with the organic peroxide formulation. Decomposition may result in the evolution of harmful, or flammable, gases or vapours. For certain organic peroxides the temperature shall be controlled during transport. Some organic peroxides may decompose explosively, particularly if confined. This characteristic may be modified by the addition of diluents or by the use of appropriate packagings. Many organic peroxides burn vigorously. Contact of organic peroxides with the eyes is to be avoided. Some organic peroxides will cause serious injury to the cornea, even after brief contact, or will be corrosive to the skin.
NOTE:
Test methods for determining the flammability of organic peroxides are set out in the Manual of Tests and Criteria, Part III, sub-section 32.4. Because organic peroxides may react vigorously when heated, it is recommended to determine their flash-point using small sample sizes such as described in ISO 3679:1983.
Classification
2.2.52.1.5. Any organic peroxide shall be considered for classification in Class 5.2 unless the organic peroxide formulation contains:
(a) Not more than 1,0 % available oxygen from the organic peroxides when containing not more than 1,0 % hydrogen peroxide;
(b) Not more than 0,5 % available oxygen from the organic peroxides when containing more than 1,0 % but not more than 7,0 % hydrogen peroxide.
NOTE:
The available oxygen content (%) of an organic peroxide formulation is given by the formula
>PIC FILE= "L_2004121EN.008601.TIF">
where:
ni= number of peroxygen groups per molecule of organic peroxide i;
ci= concentration (mass %) of organic peroxide i; and
mi= molecular mass of organic peroxide i.
2.2.52.1.6. Organic peroxides are classified into seven types according to the degree of danger they present. The types of organic peroxide range from type A, which is not accepted for carriage in the packaging in which it is tested, to type G, which is not subject to the requirements of Class 5.2. The classification of types B to F is directly related to the maximum quantity allowed in one packaging. The principles to be applied to the classification of substances not listed in 2.2.52.4 are set out in the Manual of Tests and Criteria, Part II.
2.2.52.1.7. Organic peroxides and formulations of organic peroxides which have already been classified and assigned to the appropriate generic entry are listed in 2.2.52.4 together with the applicable UN number and packing method.
These generic entries specify:
- the type (B to F) of organic peroxide (see 2.2.52.1.6 above);
- physical state (liquid/solid).
Mixtures of these formulations may be classified as the same type of organic peroxide as that of the most dangerous component and be carried under the conditions of transport given for this type. However, as two stable components can form a thermally less stable mixture, the self-accelerating decomposition temperature (SADT) of the mixture shall be determined.
2.2.52.1.8. Classification of organic peroxides, formulations or mixtures of organic peroxides not listed in 2.2.52.4 and assignment to a collective entry shall be made by the competent authority of the country of origin. The statement of approval shall contain the classification and the relevant transport conditions. If the country of origin is not a COTIF Member State, the classification and conditions of carriage shall be recognized by the competent authority of the first COTIF Member State reached by the consignment.
2.2.52.1.9. Samples of organic peroxides or formulations of organic peroxides not listed in 2.2.52.4, for which a complete set of test results is not available and which are to be carried for further testing or evaluation, shall be assigned to one of the appropriate entries for organic peroxides type C provided the following conditions are met:
- the available data indicate that the sample would be no more dangerous than organic peroxides type B;
- the sample is packaged in accordance with packing method OP2 and the quantity per wagon is limited to 10 kg;
- samples requiring temperature control shall not be accepted for carriage by rail.
Desensitization of organic peroxides
2.2.52.1.10. In order to ensure safety during carriage, organic peroxides are in many cases desensitized by organic liquids or solids, inorganic solids or water. Where a percentage of a substance is stipulated, this refers to the percentage by mass, rounded to the nearest whole number. In general, desensitization shall be such that, in case of spillage, the organic peroxide will not concentrate to a dangerous extent.
2.2.52.1.11. Unless otherwise stated for the individual organic peroxide formulation, the following definition(s) shall apply to diluents used for desensitization:
- diluents type A are organic liquids which are compatible with the organic peroxide and which have a boiling point of not less than 150 °C. Type A diluents may be used for desensitizing all organic peroxides.
- diluents type B are organic liquids which are compatible with the organic peroxide and which have a boiling point of less than 150 °C but not less than 60 °C and a flash-point of not less than 5 °C.
Type B diluents may be used for desensitization of all organic peroxides provided that the boiling point of the liquid is at least 60 °C higher than the SADT in a 50 kg package.
2.2.52.1.12. Diluents, other than type A or type B, may be added to organic peroxide formulations as listed in 2.2.52.4 provided that they are compatible. However, replacement of all or part of a type A or type B diluent by another diluent with differing properties requires that the organic peroxide formulation be re-assessed in accordance with the normal acceptance procedure for Class 5.2.
2.2.52.1.13. Water may only be used for the desensitization of organic peroxides which are listed in 2.2.52.4 or in the competent authority decision according to 2.2.52.1.8 as being "with water" or "as a stable dispersion in water". Samples of organic peroxides or formulations of organic peroxides not listed in 2.2.52.4 may also be desensitized with water provided the requirements of 2.2.52.1.9 are met.
2.2.52.1.14. Organic and inorganic solids may be used for desensitization of organic peroxides provided that they are compatible. Compatible liquids and solids are those which have no detrimental influence on the thermal stability and hazard type of the organic peroxide formulation.
2.2.52.1.15. - 2.2.52.1.18. (Reserved)
2.2.52.2. Substances not accepted for carriage

2.2.61. Class 6.1 Toxic substances
2.2.61.1. Criteria
2.2.61.1.1. The heading of Class 6.1 covers substances of which it is known by experience or regarding which it is presumed from experiments on animals that in relatively small quantities they are able by a single action or by action of short duration to cause damage to human health, or death, by inhalation, by cutaneous absorption or by ingestion.
2.2.61.1.2. Substances of Class 6.1 are subdivided as follows:
>TABLE>
Definitions
2.2.61.1.3. For the purposes of this Directive:
LD50 for acute oral toxicity is that dose of the substance administered which is most likely to cause death within 14 days in one half of both male and female young adult albino rats. The number of animals tested shall be sufficient to give a statistically significant result and be in conformity with good pharmacological practice. The result is expressed in milligrams per kg body mass.
LD50 for acute dermal toxicity is that dose of the substance which, administered by continuous contact for 24 hours with the bare skin of albino rabbits, is most likely to cause death within 14 days in one half of the animals tested. The number of animals tested shall be sufficient to give a statistically significant result and be in conformity with good pharmacological practice. The result is expressed in milligrams per kg body mass.
LC50 for acute toxicity on inhalation is that concentration of vapour, mist or dust which, administered by continuous inhalation to both male and female young adult albino rats for one hour, is most likely to cause death within 14 days in one half of the animals tested. A solid substance shall be tested if at least 10 % (by mass) of its total mass is likely to be dust in a respirable range, e.g. the aerodynamic diameter of that particle-fraction is 10 μm or less. A liquid substance shall be tested if a mist is likely to be generated in a leakage of the transport containment. Both for solid and liquid substances more than 90 % (by mass) of a specimen prepared for inhalation toxicity shall be in the respirable range as defined above. The result is expressed in milligrams per litre of air for dusts and mists or in millilitres per cubic metre of air (parts per million) for vapours.
Classification and assignment of packing groups
2.2.61.1.4. Substances of Class 6.1 shall be classified in three packing groups according to the degree of danger they present for carriage, as follows:
Packing group I: highly toxic substances
Packing group II: toxic substances
Packing group III: slightly toxic substances.
2.2.61.1.5. Substances, mixtures, solutions and articles classified in Class 6.1 are listed in table A of Chapter 3.2. The assignment of substances, mixtures and solutions not mentioned by name in table A of Chapter 3.2 to the relevant entry of 2.2.61.3 and to the relevant packing group in accordance with the requirements of Chapter 2.1, shall be made according to the following criteria in 2.2.61.1.6 to 2.2.61.1.11.
2.2.61.1.6. To assess the degree of toxicity, account shall be taken of human experience of instances of accidental poisoning, as well as special properties possessed by any individual substances: liquid state, high volatility, any special likelihood of cutaneous absorption, and special biological effects.
2.2.61.1.7. In the absence of observations on humans, the degree of toxicity shall be assessed using the available data from animal experiments in accordance with the table below:
>TABLE>
2.2.61.1.7.1. Where a substance exhibits different degrees of toxicity for two or more kinds of exposure, it shall be classified under the highest such degree of toxicity.
2.2.61.1.7.2. Substances meeting the criteria of Class 8 and with an inhalation toxicity of dusts and mists (LC50) leading to packing group I shall only be accepted for an allocation to Class 6.1 if the toxicity through oral ingestion or dermal contact is at least in the range of packing groups I or II. Otherwise an assignment to Class 8 shall be made if appropriate(see footnote (6) in 2.2.8.1.4).
2.2.61.1.7.3. The criteria for inhalation toxicity of dusts and mists are based on LC50 data relating to 1-hour exposure, and where such information is available it shall be used. However, where only LC50 data relating to 4-hour exposure are available, such figures can be multiplied by four and the product substituted in the above criteria, i.e. LC50 value multiplied by four (4 hour) is considered the equivalent of LC50 (1 hour).
Inhalation toxicity of vapours
2.2.61.1.8. Liquids giving off toxic vapours shall be classified into the following groups where "V" is the saturated vapour concentration (volatility) (in ml/m3 of air) at 20 °C and standard atmospheric pressure:
>TABLE>
These criteria for inhalation toxicity of vapours are based on LC50 data relating to 1-hour exposure, and where such information is available, it shall be used.
However, where only LC50 data relating to 4-hour exposure to the vapours are available, such figures can be multiplied by two and the product substituted in the above criteria, i.e. LC50 (4 hour) × 2 is considered the equivalent of LC50 (1 hour).

In this figure, the criteria are expressed in graphical form, as an aid to easy classification. However, due to approximations inherent in the use of graphs, substances falling on or near group borderlines shall be checked using numerical criteria.
Mixtures of liquids
2.2.61.1.9. Mixtures of liquids which are toxic on inhalation shall be assigned to packing groups according to the following criteria:
2.2.61.1.9.1. If LC50 is known for each of the toxic substances constituting the mixture, the packing group may be determined as follows:
(a) calculation of the LC50 of the mixture:
>PIC FILE= "L_2004121EN.010401.TIF">
where
fi= molar fraction of constituent i of the mixture.
LC50i= average lethal concentration of constituent i in ml/m3.
(b) calculation of volatility of each mixture constituent:
>PIC FILE= "L_2004121EN.010402.TIF">
where
Pi= partial pressure of constituent i in kPa at 20 °C and at standard atmospheric pressure.
(c) calculation of the ratio of volatility to LC50:
>PIC FILE= "L_2004121EN.010403.TIF">
(d) the values calculated for LC50 (mixture) and R are then used to determine the packing group of the mixture:
Packing group I R >= 10 and LC50 (mixture) <= 1000 ml/m3;
Packing group II R >= 1 and LC50 (mixture) <= 3000 ml/m3, if the mixture does not meet the criteria for packing group I
Packing group III R >= 1/5 and LC50 (mixture) <= 5000 ml/m3, if the mixture does not meet the criteria of packing groups I or II.
2.2.61.1.9.2. In the absence of LC50 data on the toxic constituent substances, the mixture may be assigned to a group based on the following simplified threshold toxicity tests. When these threshold tests are used, the most restrictive group shall be determined and used for carrying the mixture.
2.2.61.1.9.3. A mixture is assigned to packing group I only if it meets both of the following criteria:
(a) A sample of the liquid mixture is vaporized and diluted with air to create a test atmosphere of 1000 ml/m3 vaporized mixture in air. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have an LC50 equal to or less than 1000 ml/m3;
(b) A sample of vapour in equilibrium with the liquid mixture is diluted with 9 equal volumes of air to form a test atmosphere. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have a volatility equal to or greater than 10 times the mixture LC50.
2.2.61.1.9.4. A mixture is assigned to packing group II only if it meets both of the following criteria, and does not meet the criteria for packing group I:
(a) A sample of the liquid mixture is vaporized and diluted with air to create a test atmosphere of 3000 ml/m3 vaporized mixture in air. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have an LC50 equal to or less than 3000 ml/m3;
(b) A sample of the vapour in equilibrium with the liquid mixture is used to form a test atmosphere. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have a volatility equal to or greater than the mixture LC50.
2.2.61.1.9.5. A mixture is assigned to packing group III only if it meets both of the following criteria, and does not meet the criteria for packing groups I or II:
(a) A sample of the liquid mixture is vaporized and diluted with air to create a test atmosphere of 5000 ml/m3 vaporized mixture in air. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have an LC50 equal to or less than 5000 ml/m3;
(b) The vapour concentration (volatility) of the liquid mixture is measured and if the vapour concentration is equal to or greater than 1000 ml/m3, the mixture is presumed to have a volatility equal to or greater than 1/5 the mixture LC50.
Methods for determining oral and dermal toxicity of mixtures
2.2.61.1.10. When classifying and assigning the appropriate packing group to mixtures in Class 6.1 in accordance with the oral and dermal toxicity criteria (see 2.2.61.1.3), it is necessary to determine the acute LD50 of the mixture.
2.2.61.1.10.1. If a mixture contains only one active substance, and the LD50 of that constituent is known, in the absence of reliable acute oral and dermal toxicity data on the actual mixture to be carried, the oral or dermal LD50 may be obtained by the following method:
>PIC FILE= "L_2004121EN.010501.TIF">
2.2.61.1.10.2. If a mixture contains more than one active constituent, there are three possible approaches that may be used to determine the oral or dermal LD50 of the mixture. The preferred method is to obtain reliable acute oral and dermal toxicity data on the actual mixture to be carried. If reliable, accurate data is not available, then either of the following methods may be performed:
(a) Classify the formulation according to the most hazardous constituent of the mixture as if that constituent were present in the same concentration as the total concentration of all active constituents; or
(b) Apply the formula:
>PIC FILE= "L_2004121EN.010502.TIF">
where:
C= the percentage concentration of constituent A, B, ... Z in the mixture
T= the oral LD50 values of constituent A, B, ... Z
TM= the oral LD50 value of the mixture.
NOTE:
This formula can also be used for dermal toxicities provided that this information is available for all constituents. The use of this formula does not take into account any potentiation or protective phenomena.
Classification of pesticides
2.2.61.1.11. All active pesticide substances and their preparations for which the LC50 and/or LD50 values are known and which are classified in Class 6.1 shall be classified under appropriate packing groups in accordance with the criteria given in 2.2.61.1.6 to 2.2.61.1.9. Substances and preparations which are characterized by subsidiary risks shall be classified according to the precedence of hazard table in 2.1.3.9 with the assignment of appropriate packing groups.
2.2.61.1.11.1. If the oral or dermal LD50 value for a pesticide preparation is not known, but the LD50 value of its active substance(s) is known, the LD50 value for the preparation may be obtained by applying the procedures in 2.2.61.1.10.
NOTE:
LD50 toxicity data for a number of common pesticides may be obtained from the most current edition of the document "The WHO Recommended Classification of Pesticides by Hazard and Guidelines to Classification" available from the International Programme on Chemical Safety, World Health Organisation (WHO), 1211 Geneva 27, Switzerland. While that document may be used as a source of LD50 data for pesticides, its classification system shall not be used for purposes of transport classification of, or assignment of packing groups to, pesticides, which shall be in accordance with the requirements of this Directive.
2.2.61.1.11.2. The proper shipping name used in the transport of the pesticide shall be selected on the basis of the active ingredient, of the physical state of the pesticide and any subsidiary risks it may exhibit (see 3.1.2).
2.2.61.1.12. If substances of Class 6.1, as a result of admixtures, come into categories of risk different from those to which the substances mentioned by name in table A of Chapter 3.2 belong, these mixtures or solutions shall be listed under the entries to which they belong on the basis of their actual degree of danger.
NOTE:
For the classification of solutions and mixtures (such as preparations and wastes), see also 2.1.3.
2.2.61.1.13. On the basis of the criteria of 2.2.61.1.4 to 2.2.61.1.10, it may also be determined whether the nature of a solution or mixture mentioned by name or containing a substance mentioned by name is such that the solution or mixture is not subject to the requirements for this Class.
2.2.61.1.14. Substances, solutions and mixtures, with the exception of substances and preparations used as pesticides, which do not meet the criteria of Directives 67/548/EEC(11) or 88/379/EEG(12) as amended and which are not therefore classified as highly toxic, toxic or harmful according to these directives, as amended, may be considered as substances not belonging to Class 6.1.
2.2.61.2. Substances not accepted for carriage
2.2.61.2.1. Chemically unstable substances of Class 6.1 shall not be accepted for carriage unless the necessary steps have been taken to prevent their dangerous decomposition or polymerization during carriage. To this end, it shall in particular be ensured that receptacles and tanks do not contain any substance(s) likely to cause such a reaction.
2.2.61.2.2. The following substances and mixtures shall not be accepted for carriage:
- Hydrogen cyanides (stabilized or in solutions), other than UN Nos 1051, 1613, 1614 and 3294;

2.2.62 Class 6.2 Infectious substances
2.2.62.1. Criteria
2.2.62.1.1. The heading of Class 6.2 covers infectious substances. Infectious substances are those substances known or reasonably expected to contain pathogens. Pathogens are defined as micro-organisms (including bacteria, viruses, rickettsia, parasites, fungi) or recombinant micro-organisms (hybrid or mutant), that are known or reasonably expected to cause infectious disease in animals or humans.
For the purposes of this Class, viruses, micro-organisms as well as articles contaminated with these shall be considered as substances of this Class.
NOTES:
1. However, they are not subject to the requirements applicable to this Class if they are unlikely to cause human or animal disease.
2. Infectious substances are subject to the requirements applicable to this Class only if they are capable of spreading disease to humans or animals when exposure to them occurs.
3. Genetically modified micro-organisms and organisms, biological products, diagnostic specimens and infected live animals shall be assigned to this Class if they meet the conditions for this Class.
4. Toxins from plant, animal or bacterial sources which do not contain any infectious substances or organisms or which are not contained in them are substances of Class 6.1, UN No 3172.
2.2.62.1.2. Substances of Class 6.2 are subdivided as follows:
>TABLE>
Definitions and classification
2.2.62.1.3. Infectious substances shall be classified in Class 6.2 and assigned to UN Nos 2814 or 2900, as appropriate, on the basis of their allocation to one of three risk groups based on criteria developed by the World Health Organization (WHO) and published in the WHO "Laboratory Biosafety Manual, second edition (1993)". A risk group is characterized by the pathogenicity of the organism, the mode and relative ease of transmission, the degree of risk to both an individual and a community, and the reversibility of the disease through the availability of known and effective preventive agents and treatment.
The criteria for each risk group according to the level of risk are as follows:
(a) Risk group 4: a pathogen that usually causes serious human or animal disease and that can be readily transmitted from one individual to another, directly or indirectly, and for which effective treatment and preventive measures are not usually available (i.e., high individual and community risk).
(b) Risk group 3: a pathogen that usually causes serious human or animal disease but does not ordinarily spread from one infected individual to another, and for which effective treatment and preventive measures are available (i.e. high individual risk and low community risk).
(c) Risk group 2: a pathogen that can cause human or animal disease but is unlikely to be a serious hazard, and, while capable of causing serious infection on exposure, for which effective treatment and preventive measures are available and the risk of spread of infection is limited (i.e. moderate individual risk and low community risk).
NOTE:
Risk group 1 includes micro-organisms that are unlikely to cause human or animal disease (i.e. no, or very low, individual or community risk). Substances containing only such micro-organisms are not considered infectious substances for the purposes of these requirements.
2.2.62.1.4. Infectious substances affecting animals only (group I2 in 2.2.62.1.2) and of risk group 2 are assigned to packing group II.
2.2.62.1.5. Biological products are those products derived from living organisms, that are manufactured and distributed in accordance with the requirements of national governmental authorities which may have special licensing requirements, and are used either for prevention, treatment, or diagnosis of disease in humans or animals, or for development, experimental or investigational purposes related thereto. They include, but are not limited to, finished or unfinished products such as vaccines and diagnostic products.
For the purposes of this Directive, biological products are divided into the following groups:
(a) Those which contain pathogens in risk group 1; those which contain pathogens under such conditions that their ability to produce disease is very low to none; and those known not to contain pathogens. Substances in this group are not considered infectious substances for the purposes of this Directive;
(b) Those manufactured and packaged in accordance with the requirements of national governmental health authorities and transported for the purposes of final packaging or distribution, and use for personal health care by medical professionals or individuals. Substances in this group are not subject to the requirements applicable to Class 6.2;
(c) Those known or reasonably expected to contain pathogens in risk groups 2, 3, or 4 and which do not meet the criteria of (b) above. Substances in this group shall be classified in Class 6.2 under UN Nos 2814 or 2900, as appropriate.
NOTE:
Some licensed biological products may present a biohazard in certain parts of the world only. In that case competent authorities may require these biological products to comply with the requirements for infectious substances or may impose other restrictions.
2.2.62.1.6. Diagnostic specimens are any human or animal material including, but not limited to, excreta, secreta, blood and its components, tissue and tissue fluids being transported for purposes of diagnosis or research, but excluding live infected animals.
For the purposes of RID, diagnostic specimens are divided into the following groups:
(a) Those known or reasonably expected to contain pathogens in risk groups 2, 3 or 4 and those where a relatively low probability exists that pathogens of risk group 4 are present. Such substances shall be classified in Class 6.2 under UN Nos 2814 or 2900, as appropriate. Specimens carried for the purposes of initial or confirmatory testing for the presence of pathogens fall within this group;
(b) Those where a relatively low probability exists that pathogens of risk groups 2 or 3 are present. Such substances shall be classified in 6.2 under UN No 2814 or 2900, as appropriate. Specimens carried for the purpose of initial diagnosis for other than the presence of pathogens or specimens arried for routine screening fall within this group;
(c) Those known not to contain pathogens. Such substances are not considered as substances of Class 6.2.
2.2.62.1.7. Genetically modified micro-organisms and organisms(13) are micro-organisms and organisms in which the genetic material has been deliberately altered by technical methods or by means that cannot occur naturally in nature.
For the purposes of RID, genetically modified micro-organisms and organisms are divided into the following groups:
(a) Genetically modified micro-organisms which meet the definition of an infectious substance given in 2.2.62.1.1 shall be classified in Class 6.2 and assigned to UN Nos 2814 or 2900;
(b) Genetically modified organisms, which are known or suspected to be dangerous to humans, animals or the environment, shall be carried in accordance with conditions specified by the competent authority of the country of origin;
(c) Animals which contain or are contaminated with genetically modified micro-organisms and organisms that meet the definition of an infectious substance shall be carried in accordance with conditions specified by the competent authority of the country of origin;
(d) Except when authorized for unconditional use by the Governments of the countries of origin, transit and destination, genetically modified micro-organisms which do not meet the definition of infectious substances but which are capable of altering animals, plants or microbiological substances in a way not normally the result of natural reproduction shall be classified in Class 9 and assigned to UN No 3245.
NOTE:
Genetically modified micro-organisms which are infectious within the meaning of this Class may not be assigned to UN No 3291.
2.2.62.1.8. Diagnostic specimens referred to in 2.2.62.1.6 (b) need not meet the requirements for infectious substances when the following conditions are met:
(a) - The primary receptacle(s) do not contain more than 100 ml;
- The outer packaging does not contain more than 500 ml;
- The primary receptacle(s) are leakproof; and
- The packaging includes:
(i) an inner packaging comprising:
- watertight primary receptacle(s);
- a watertight secondary packaging;
- absorbent material in sufficient quantity to absorb the entire contents placed between the primary receptacle(s) and the secondary packaging; if several primary receptacles are placed in a single secondary packaging, they shall be individually wrapped so as to prevent contact between them;
(ii) an outer packaging of adequate strength for its capacity, mass and intended use, and with minimum external dimensions of 100 mm, or
(b) the packagings comply with standard EN 829:1996.
2.2.62.1.9. Wastes are wastes derived from the medical treatment of animals or humans or from bioresearch where there is a relatively low probability that infectious substances are present. They shall be assigned to UN No 3291. Wastes containing infectious substances which can be specified shall be assigned to UN Nos 2814 or 2900 according to their degree of danger (see 2.2.62.1.3). Decontaminated wastes which previously contained infectious substances are considered non-dangerous unless the criteria of another class are met.
2.2.62.1.10. Clinical wastes assigned to UN No 3291 are assigned to packing group II.
2.2.62.1.11. For the carriage of substances of this Class, the maintenance of a specified temperature may be necessary.
2.2.62.2. Substances not accepted for carriage
Live vertebrate or invertebrate animals shall not be used to carry an infectious agent unless the agent cannot be carried by any other means. Such animals shall be packed, marked, indicated, and carried in accordance with the relevant regulations governing the carriage of animals(14).

2.2.7.6.1. Determination of transport index
2.2.7.6.1.1. The transport index (TI) for a package, overpack or container, or for unpackaged LSA-I or SCO-I, shall be the number derived in accordance with the following procedure:
(a) Determine the maximum radiation level in units of millisieverts per hour (mSv/h) at a distance of 1 m from the external surfaces of the package, overpack, container, or unpackaged LSA-I and SCO-I. The value determined shall be multiplied by 100 and the resulting number is the transport index. For uranium and thorium ores and their concentrates, the maximum radiation level at any point 1 m from the external surface of the load may be taken as:
0,4 mSv/h for ores and physical concentrates of uranium and thorium;
0,3 mSv/h for chemical concentrates of thorium;
0,02 mSv/h for chemical concentrates of uranium, other than uranium hexafluoride;
(b) For tanks, containers and unpackaged LSA-I and SCO-I, the value determined in step (a) above shall be multiplied by the appropriate factor from Table 2.2.7.6.1.1;
(c) The value obtained in steps (a) and (b) above shall be rounded up to the first decimal place (e.g. 1.13 becomes 1.2), except that a value of 0,05 or less may be considered as zero.
Table 2.2.7.6.1.1

For individual radionuclides which are not listed in Table 2.2.7.7.2.1 the determination of the basic radionuclide values referred to in 2.2.7.7.2.1 shall require competent authority approval or, for international transport, multilateral approval. Where the chemical form of each radionuclide is known, it is permissible to use the A2 value related to its solubility class as recommended by the International Commission on Radiological Protection, if the chemical forms under both normal and accident conditions of transport are taken into consideration. Alternatively, the radionuclide values in Table 2.2.7.7.2.2 may be used without obtaining competent authority approval.
Table 2.2.7.7.2.2
Basic radionuclide values for unknown radionuclides or mixtures
>TABLE>
2.2.7.7.2.3. In the calculations of A1 and A2 for a radionuclide not in Table 2.2.7.7.2.1, a single radioactive decay chain in which the radionuclides are present in their naturally occurring proportions, and in which no daughter nuclide has a half-life either longer than 10 days or longer than that of the parent nuclide, shall be considered as a single radionuclide; and the activity to be taken into account and the A1 or A2 value to be applied shall be those corresponding to the parent nuclide of that chain. In the case of radioactive decay chains in which any daughter nuclide has a half-life either longer than 10 days or greater than that of the parent nuclide, the parent and such daughter nuclides shall be considered as mixtures of different nuclides.
2.2.7.7.2.4. For mixtures of radionuclides, the determination of the basic radionuclide values referred to in 2.2.7.7.2.1 may be determined as follows:
>PIC FILE= "L_2004121EN.013601.TIF">
where,
f(i) is the fraction of activity or activity concentration of radionuclide i in the mixture;
X(i) is the appropriate value of A1 or A2, or the activity concentration for exempt material or the activity limit for an exempt consignment as appropriate for the radionuclide i; and
Xm is the derived value of A1 or A2, or the activity concentration for exempt material or the activity limit for an exempt consignment in the case of a mixture.
2.2.7.7.2.5. When the identity of each radionuclide is known but the individual activities of some of the radionuclides are not known, the radionuclides may be grouped and the lowest radionuclide value, as appropriate, for the radionuclides in each group may be used in applying the formulas in 2.2.7.7.2.4 and 2.2.7.7.1.4.2. Groups may be based on the total alpha activity and the total beta/gamma activity when these are known, using the lowest radionuclide values for the alpha emitters or beta/gamma emitters, respectively.
2.2.7.7.2.6. For individual radionuclides or for mixtures of radionuclides for which relevant data are not available, the values shown in Table 2.2.7.7.2.2 shall be used.

(a) For a package or overpack, both the transport index and the surface radiation level conditions shall be taken into account in determining which is the appropriate category. Where the transport index satisfies the condition for one category but the surface radiation level satisfies the condition for a different category, the package or overpack shall be assigned to the higher category. For this purpose, category I-WHITE shall be regarded as the lowest category;
(b) The transport index shall be determined following the procedures specified in 2.2.7.6.1.1 and 2.2.7.6.1.2;

2.2.8. Class 8 Corrosive substances
2.2.8.1. Criteria
2.2.8.1.1. The heading of Class 8 covers substances and articles containing substances of this Class which by chemical action attack epithelial tissue - of skin or mucous membranes - with which they are in contact, or which in the event of leakage are capable of damaging or destroying other goods, or means of transport, and may also cause other hazards. The heading of this Class also covers other substances which form a corrosive liquid only in the presence of water, or which produce corrosive vapour or mist in the presence of natural moisture of the air.
2.2.8.1.2. Substances and articles of Class 8 are subdivided as follows:
>TABLE>
Classification and assignment of packing groups
2.2.8.1.3. Substances of Class 8 shall be assigned to one of the following packing groups according to the degree of danger they present for carriage, as follows:
Packing group I: highly corrosive substances
Packing group II: corrosive substances
Packing group III: slightly corrosive substances.
2.2.8.1.4. Substances and articles classified in Class 8 are listed in table A of Chapter 3.2. Allocation of substances to packing groups I, II and III has been made on the basis of experience taking into account such additional factors as inhalation risk(15) and reactivity with water (including the formation of dangerous decomposition products).
2.2.8.1.5. Substances, including mixtures, not mentioned by name in table A of Chapter 3.2 can be assigned to the relevant entry of 2.2.8.3, and to the relevant packing group on the basis of the length of time of contact necessary to produce full thickness destruction of human skin in accordance with the criteria of (a) to (c) below.
Substances which are judged not to cause full thickness destruction of human skin shall still be considered for their potential to cause corrosion to certain metal surfaces.
In assigning the packing group, account shall be taken of human experience in instances of accidental exposure.
In the absence of human experience, the grouping shall be based on data obtained from experiments in accordance with OECD Guideline 404(16).
(a) Packing group I is assigned to substances that cause full thickness destruction of intact skin tissue within an observation period up to 60 minutes starting after the exposure time of 3 minutes or less.
(b) Packing group II is assigned to substances that cause full thickness destruction of intact skin tissue within an observation period up to 14 days starting after the exposure time of more than 3 minutes but not more than 60 minutes.
(c) Packing group III is assigned to substances that:
- cause full thickness destruction of intact skin tissue within an observation period up to 14 days starting after the exposure time of more than 60 minutes but not more than 4 hours; or
- are judged not to cause full thickness destruction of intact skin tissue, but which exhibit a corrosion rate on steel or aluminium surfaces exceeding 6,25 mm a year at a test temperature of 55 °C.
For the purposes of testing steel, type P235 [ISO 9328(II):1991] or a similar type, and for testing aluminium, non-clad types 7075-T6 or AZ5GU-T6 shall be used. An acceptable test is prescribed in ASTM G31-72 (Reapproved 1990).
2.2.8.1.6. If substances of Class 8, as a result of admixtures, come into categories of risk different from those to which the substances mentioned by name in table A of Chapter 3.2 belong, these mixtures or solutions shall be assigned to the entries to which they belong, on the basis of their actual degree of danger.
NOTE:
For the classification of solutions and mixtures (such as preparations and wastes), see also 2.1.3.

Test methods
2.3.0. General
Unless otherwise provided for in Chapter 2.2 or in this section, the test methods to be used for the classification of dangerous goods are those described in the Manual of Tests and Criteria.
2.3.1. Exudation test for blasting explosives of type A
2.3.1.1. Blasting explosives of type A (UN 0081) shall, if they contain more than 40 % liquid nitric ester, in addition to the testing specified in the Manual of Tests and Criteria, satisfy the following exudation test.
2.3.1.2. The apparatus for testing blasting explosive for exudation (figs. 1 to 3) consists of a hollow bronze cylinder. This cylinder, which is closed at one end by a plate of the same metal, has an internal diameter of 15,7 mm and a depth of 40 mm. It is pierced by 20 holes 0,5 mm in diameter (four sets of five holes) on the circumference. A bronze piston, cylindrically fashioned over a length of 48 mm and having a total length of 52 mm, slides into the vertically placed cylinder. The piston, whose diameter is 15,6 mm, is loaded with a mass of 2220 g so that a pressure of 120 kPa (1,2 bar) is exerted on the base of the cylinder.
2.3.1.3. A small plug of blasting explosive weighing 5 to 8 g, 30 mm long and 15 mm in diameter, is wrapped in very fine gauze and placed in the cylinder; the piston and its loading mass are then placed on it so that the blasting explosive is subjected to a pressure of 120 kPa (1,2 bar). The time taken for the appearance of the first signs of oily droplets (nitroglycerin) at the outer orifices of the cylinder holes is noted.
2.3.1.4. The blasting explosive is considered satisfactory if the time elapsing before the appearance of the liquid exudations is more than five minutes, the test having been carried out at a temperature of 15 °C to 25 °C.

2.3.2.4. If other test procedures are used to verify the conditions of stability referred to above, these procedures shall lead to the same findings as could be reached by the methods specified below.
2.3.2.5. In carrying out the stability tests by heating described below, the temperature of the oven containing the sample under test shall not deviate by more than 2 °C from the prescribed temperature; the prescribed duration of a 30-minute or 60-minute test shall be observed to within two minutes. The oven shall be such that the required temperature is restored not more than five minutes after insertion of the sample.
2.3.2.6. Before undergoing the tests in 2.3.2.9 and 2.3.2.10, the samples shall be dried for not less than 15 hours at the ambient temperature in a vacuum desiccator containing fused and granulated calcium chloride, the sample substance being spread in a thin layer; for this purpose, substances which are neither in powder form nor fibrous shall be ground, or grated, or cut into small pieces. The pressure in the desiccator shall be brought below 6,5 kPa (0,065 bar).
2.3.2.7. Before being dried as prescribed in 2.3.2.6 above, substances conforming to 2.3.2.2 shall undergo preliminary drying in a well-ventilated oven, with its temperature set at 70 °C, until the loss of mass per quarter-hour is less than 0,3 % of the original mass.
2.3.2.8. Weakly nitrated nitrocellulose conforming to 2.3.2.1 shall first undergo preliminary drying as prescribed in 2.3.2.7 above; drying shall then be completed by keeping the nitrocellulose for at least 15 hours over concentrated sulphuric acid in a desiccator.
2.3.2.9. Test of chemical stability under heat

is placed 1 g of substance dried over calcium chloride (if necessary the drying shall be carried out after reducing the substance to pieces weighing not more than 0,05g each). Both test tubes, completely covered with loose-fitting closures, are then so placed in an oven that at least four-fifths of their length is visible, and are kept at a constant temperature of 132 °C for 30 minutes. It is observed whether nitrous gases in the form of yellowish-brown fumes clearly visible against a white background are given off during this time.
(ii) In the absence of such fumes the substance is deemed to be stable.
(b) Test of plasticized nitrocellulose (see 2.3.2.2).
(i) 3 g of plasticized nitrocellulose are placed in glass test tubes, similar to those referred to in (a), which are then placed in an oven kept at a constant temperature of 132 °C.
(ii) The test tubes containing the plasticized nitrocellulose are kept in the oven for one hour. During this time no yellowish-brown nitrous fumes (nitrous gases) shall be visible. Observation and appraisal as in (a).
2.3.2.10. Ignition temperature (see 2.3.2.1 and 2.3.2.2)
(a) The ignition temperature is determined by heating 0,2 g of substance enclosed in a glass test tube immersed in a Wood's alloy bath. The test tube is placed in the bath when the latter has reached 100 °C. The temperature of the bath is then progressively increased by 5 °C per minute.
(b) The test tubes must have the following dimensions:
length ... 125 mm,

2.3.3.1.6. The test methods listed in 2.3.3.1.4 and 2.3.3.1.5 shall only be used for flash-point ranges which are specified in the individual methods. The possibility of chemical reactions between the substance and the sample holder shall be considered when selecting the method to be used. The apparatus shall, as far as is consistent with safety, be placed in a draught-free position. For safety, a method utilizing a small sample size, around 2 ml, shall be used for organic peroxides and self-reactive substances (also known as "energetic" substances), or for toxic substances.
2.3.3.1.7. When the flash-point, determined by a non-equilibrium method in accordance with 2.3.3.1.3 is found to be 23 ± 2 °C or 61 ± 2 °C, it shall be confirmed for each temperature range by an equilibrium method in accordance with 2.3.3.1.2
2.3.3.1.8. In the event of a dispute as to the classification of a flammable liquid, the classification proposed by the consignor shall be accepted if a check-test of the flash-point, yields a result not differing by more than 2 °C from the limits (23 °C and 61 °C respectively) stated in 2.2.3.1.

When it has been left to cool for 5 minutes, 25 cm3 of water are added. After this, it is left standing for half an hour, then the liberated iodine is titrated with a decinormal solution of sodium thiosulphate, no indicator being added; complete discoloration indicates the end of the reaction. If n is the number of cm3 of thiosulphate solution required, the percentage of peroxide (calculated as H2O2) present in the sample is obtained by the formula
>PIC FILE= "L_2004121EN.015001.TIF">
2.3.4. Test for determining fluidity
To determine the fluidity of liquid, viscous or pasty substances and mixtures, the following test method shall be used.
2.3.4.1. Test apparatus
Commercial penetrometer conforming to ISO Standard 2137-1985, with a guide rod of 47,5 g ± 0,05 g; sieve disc of duralumin with conical bores and a mass of 102,5 g ± 0,05 g (see Figure 1); penetration vessel with an inside diameter of 72 mm to 80 mm for reception of the sample.
2.3.4.2. Test procedure
The sample is poured into the penetration vessel not less than half an hour before the measurement. The vessel is then hermetically closed and left standing until the measurement. The sample in the hermetically closed penetration vessel is heated to 35 °C ± 0,5 °C and is placed on the penetrometer table immediately prior to measurement (not more than two minutes). The point S of the sieve disc is then brought into contact with the surface of the liquid and the rate of penetration is measured.
2.3.4.3. Evaluation of test results
A substance is pasty if, after the centre S has been brought into contact with the surface of the sample, the penetration indicated by the dial gauge:
(a) after a loading time of 5 s ± 0,1 s, is less than 15,0 mm ± 0,3 mm; or
(b) after a loading time of 5 s ± 0,1 s, is greater than 15,0 mm ± 0,3 mm, but the additional penetration after another 55 s ± 0,5 s is less than 5,0 mm ± 0,5 mm.
NOTE:
In the case of samples having a flow point, it is often impossible to produce a steady level surface in the penetration vessel and, hence, to establish satisfactory initial measuring conditions for the contact of the point S. Furthermore, with some samples, the impact of the sieve disc can cause an elastic deformation of the surface and, in the first few seconds, simulate a deeper penetration. In all these cases, it may be appropriate to make the evaluation in (b).

>PIC FILE= "L_2004121EN.015101.TIF">
2.3.5. Test for determining the ecotoxicity, persistence and bioaccumulation of substances in the aquatic environment for assignment to Class 9
NOTE:
The test methods used shall be those adopted by the Organization for Economic Cooperation and Development (OECD) and the European Commission (EC). If other methods are used, they shall be internationally recognized, be equivalent to the OECD/EC tests and be referenced in test reports.
2.3.5.1. Acute toxicity for fish
The object is to determine the concentration which causes 50 % mortality in the test species; this is the (LC50) value, namely, the concentration of the substance in water which will cause the death of 50 % of a test group of fish during a continuous period of testing of at least 96 hours. Appropriate types of fish include: striped brill (Brachydanio rerio), fathead minnow (Pimephales promelas) and rainbow trout (Oncorhynchus mykiss).
The fish are exposed to the test substance added to the water in varying concentrations (+1 control). Observations are recorded at least every 24 hours. At the end of the 96-hour activity and, if possible, at each observation, the concentration causing the death of 50 % of the fish is calculated. The no observed effect concentration (NOEC) at 96 hours is also determined.
2.3.5.2. Acute toxicity for daphnia
The object is to determine the effective concentration of the substance in water which renders 50 % of the daphnia unable to swim (EC50). The appropriate test organisms are daphnia magna and daphnia pulex. The daphnia are exposed for 48 hours to the test substance added to the water in varying concentrations. The no observed effect concentration (NOEC) at 48 hours is also determined.
2.3.5.3. Algal growth inhibition
The object is to determine the effect of a chemical on the growth of algae under standard conditions. The change in biomass and the rate of growth with algae under the same conditions, but without the presence of the test chemical, are compared over 72 hours. The results are expressed as the effective concentration which reduces the rate of algal growth by 50 %, IC50r, and also the formation of the biomass, IC50b.
2.3.5.4. Tests for ready biodegradability
The object is to determine the degree of biodegradation under standard aerobic conditions. The test substance is added in low concentrations to a nutrient solution containing aerobic bacteria. The progress of degradation is followed for 28 days by determining the parameter specified in the test method used. Several equivalent test methods are available.
The parameters include reduction of dissolved organic carbon (DOC),
carbon dioxide (CO2),
generation of oxygen (O2) depletion.
A substance is considered to be readily biodegradable if within not more than 28 days the following criteria are satisfied-within 10 days from when degradation first reaches 10 %:
Reduction of DOC: 70 %
Generation of CO2: 60 % of theoretical CO2 production
Depletion of O2: 60 % of theoretical O2 requirement.
The test may be continued beyond 28 days if the above criteria are not satisfied, but the result will represent the inherent biodegradability of the test substance. For assignment purposes, the "ready" result is normally required.
Where only COD and BOD5 data are available, a substance is considered to be readily biodegradable if:
>PIC FILE= "L_2004121EN.015301.TIF">
BOD (Biochemical Oxygen Demand) is defined as the mass of dissolved oxygen required by a specific volume of solution of the substance for the process of biochemical oxidation under prescribed conditions. The result is expressed as grams of BOD per gram of test substance. The normal test period is five days (BOD5) using a national standard test procedure.
COD (Chemical Oxygen Demand) is a measure of the oxidizability of a substance, expressed as the equivalent amount in oxygen of an oxidizing reagent consumed by the substance under fixed laboratory conditions. The results are expressed in grams of COD per gram of substance. A national standard procedure may be used.
2.3.5.5. Tests for bioaccumulation potential
2.3.5.5.1. The object is to determine the potential for bioaccumulation either by the ratio at equilibrium of the concentration (c) of a substance in a solvent to that in water or by the bioconcentration factor (BCF).
2.3.5.5.2. The ratio at equilibrium of the concentration (c) of a substance in a solvent to that in water is normally expressed as a log10. The solvent and water shall have negligible miscibility and the substance shall not ionize in water. The solvent normally used is n-octanol.
In the case of n-octanol and water, the result is:
>PIC FILE= "L_2004121EN.015302.TIF">
where Pow is the partition coefficient obtained by dividing the concentration of the substance in n-octanol (co) by the concentration of the substance in water (cw). If log Pow >= 3,0 then the substance has a potential to bioaccumulate.
2.3.5.5.3. The bioconcentration factor (BCF) is defined as the ratio of the concentration of the test substance in the test fish (cf) to the concentration in the test water (cw) at steady state:
>PIC FILE= "L_2004121EN.015303.TIF">
The principle of the test involves exposing fish to a solution or dispersion at known concentrations of the test substance in water. Continuous flow, static or semi-static procedures may be used according to the test procedure selected, based on the properties of the test substances. Fish are exposed to the test substances over a given period of time, followed by a period of no further exposure. During the second period, measurements are made of the rate of increase in the water of the test substance (i.e. the rate of excretion or depuration).
(Full details of the various test procedures and the calculation method for the BCF are given in the OECD Guidelines for Testing of Chemicals, methods 305A to 305E, 12 May 1981).
2.3.5.5.4. A substance may have a log Pow greater than 3 and a BCF less than 100 which would indicate little or no potential to bioaccumulate. In cases of doubt, the BCF value takes precedence over log Pow, as indicated in the flow chart of the Procedure in 2.3.5.7.
2.3.5.6. Criteria
A substance may be regarded as a pollutant to the aquatic environment if it satisfies one of the following criteria:
The lowest of the values of
the 96-hour LC50 for fish,
the 48-hour EC50 for daphnia or
the 72-hour IC50 for algae:
- is less than or equal to 1 mg/l;
- is greater than 1 mg/l but less than or equal to 10 mg/l, and the substance is not biodegradable;
- is greater than 1 mg/l but less than or equal to 10 mg/l, and the log Pow is greater than or equal to 3,0 (unless the experimentally determined BCF is less than or equal to 100).

Portions of an entry appearing in lower case need not be considered as part of the proper shipping name.
3.1.2.2. When conjunctions such as "and" or "or" are in lower case or when segments of the name are punctuated by commas, the entire name of the entry need not necessarily be shown in the consignment note or package markings. This is the case particularly when a combination of several distinct entries are listed under a single UN Number. Examples illustrating the selection of the proper shipping name for such entries are:
(a) UN 1057 LIGHTERS or LIGHTER REFILLS - The proper shipping name is the most appropriate of the following possible combinations:
- LIGHTERS
- LIGHTER REFILLS;
(b) UN 3207 ORGANOMETALLIC COMPOUND or COMPOUND SOLUTION or COMPOUND DISPERSION, WATER-REACTIVE, FLAMMABLE, N.O.S. The proper shipping name is the most appropriate of the following possible combinations:
- ORGANOMETALLIC COMPOUND, WATER-REACTIVE, FLAMMABLE, N.O.S.
- ORGANOMETALLIC COMPOUND SOLUTION, WATER-REACTIVE, FLAMMABLE, N.O.S.
- ORGANOMETALLIC COMPOUND DISPERSION, WATER-REACTIVE, FLAMMABLE, N.O.S.
each supplemented with the technical name of the goods (see 3.1.2.6.1).
3.1.2.3. Proper shipping names may be used in the singular or plural as appropriate. In addition, when qualifying words are used as part of the proper shipping name, their sequence on the consignment note or package markings is optional. For instance, "Dimethylamine aqueous solution" may alternatively be shown as "aqueous solution of dimethylamine". Commercial or military names for goods of Class 1 which contain the proper shipping name supplemented by additional descriptive text may be used.
3.1.2.4. Unless it is already included in capital letters in the name indicated in table A in Chapter 3.2, the qualifying word "LIQUID" or "SOLID", as appropriate, shall be added as part of the proper shipping name when a substance specifically listed by name may, due to the differing physical states of the various isomers of the substance, be either a liquid or a solid (e.g. DINITROTOLUENES, LIQUID; DINITROTOLUENES, SOLID).
3.1.2.5. Unless it is already included in capital letters in the name indicated in table A in Chapter 3.2, the qualifying word "MOLTEN" shall be added as part of the proper shipping name when a substance, which is a solid in accordance with the definition in 1.2.1, is carried or handed over for carriage in the molten state (e.g. ALKYLPHENOL, SOLID, N.O.S., MOLTEN).
3.1.2.6. Names of generic or "not otherwise specified" (N.O.S.) entries
3.1.2.6.1. For the purposes of documentation and marking of packages, when an "N.O.S." or "generic" proper shipping name is used, the proper shipping name shall be supplemented with the technical name of the goods, unless a national law or international convention prohibits its disclosure if it is a controlled substance. The particular "N.O.S." or "generic" entries for which this supplementary information is considered necessary have been allocated Special Provision 274 in column (6) of table A in Chapter 3.2.
3.1.2.6.1.1. The technical name (see definition in 1.2.1) shall be shown immediately following the proper shipping name. Trade names shall not be used for this purpose. In the case of pesticides, only ISO common name(s), other name(s) in the WHO Recommended Classification of Pesticides by Hazard and Guidelines to Classification, or the name(s) of the active substance(s) may be used. It shall be a recognized chemical name or another name currently used in scientific and technical handbooks, journals and texts.
3.1.2.6.1.2. When a mixture of dangerous goods is described by one of the "N.O.S." or "generic" entries to which Special Provision 274 has been allocated in column (6) of table A in Chapter 3.2, not more than the two constituents which most predominantly contribute to the hazard or hazards of a mixture need to be shown, excluding controlled substances when their disclosure is prohibited by national law or international convention. If a package containing a mixture is labelled with any subsidiary risk label, one of the two technical names shown in parentheses shall be the name of the constituent which compels the use of the subsidiary risk label.
NOTE:
see 5.4.1.2.2
3.1.2.6.1.3. Examples illustrating the selection of the proper shipping name supplemented with the technical name of goods for such N.O.S. entries are:
UN 2003 METAL ALKYL, N.O.S. (trimethylgallium)
UN 2902 PESTICIDE, LIQUID, TOXIC, N.O.S. (drazoxolon).
3.1.2.7. Mixtures and solutions containing one dangerous substance
When mixtures and solutions have to be regarded as the dangerous substance listed by name in accordance with the classification requirements of 2.1.3.3, the qualifying word "SOLUTION" or "MIXTURE", as appropriate, shall be added as part of the proper shipping name, e.g. "ACETONE SOLUTION". In addition, the concentration of the solution or mixture may also be indicated, e.g. "ACETONE 75 % SOLUTION".
CHAPTER 3.2
List of dangerous goods in UN number order
3.2.1. Explanations concerning table A: List of dangerous goods in UN number order
As a rule, each row of table A in this Chapter deals with the substance(s) or article(s) covered by a specific UN number. However, when substances or articles belonging to the same UN number have different chemical properties, physical properties and/or transport conditions, several consecutive rows may be used for that UN number.
Each column of table A is dedicated to a specific subject as indicated in the explanatory notes below. The intersection of columns and rows contains information concerning the subject treated in that column, for the substance(s) or article(s) of that row:
- the first four cells identify the substance(s) or article(s) belonging to that row (additional information in that respect may be given by the special requirements referred to in column (6));
- the following cells give the applicable special requirements, either in the form of complete information or in coded form. The codes cross-refer to detailed information that is to be found in the Part, Chapter, Section and/or Sub-section indicated in the explanatory notes below. An empty cell means either that there is no special requirement and that only the general requirements apply, or that the transport restriction indicated in the explanatory notes is in force.
The applicable general requirements are not referred to in the corresponding columns. The explanatory notes below indicate for every column the Part(s), Chapter(s), Section(s) and/or Sub-section(s) where these are to be found.

PACKING AND TANK PROVISIONS
CHAPTER 4.1
Use of packagings, including intermediate bulk containers (IBCs) and large packagings
Introductory notes
NOTE 1. Packing groups
Dangerous substances of all classes other than those of classes 1, 2, 5.2, 6.2 and 7 and than the self-reactive substances of Class 4.1 have for packing purposes been assigned to one or more of three Packing Groups in accordance with the degree of danger they present, i.e.:
Packing Group I: substances presenting high danger;
Packing Group II substances presenting medium danger; and
Packing Group III substances presenting low danger.
The Packing Group to which a substance is assigned is indicated in Table A of Chapter 3.2.
NOTE 2. Explosives, self-reactive substances and organic peroxides
Unless otherwise required in this Directive, the packagings, including IBCs and large packagings, used for goods of Class l, self-reactive substances of Class 4.1 and organic peroxides of Class 5.2 shall comply with the requirements for the medium danger group (Packing Group II).
4.1.1. General Requirements for the packing of dangerous goods, other than goods of classes 2, 6.2 or 7, in packagings, including IBCs and large packagings
NOTE.
Some of these general requirements may apply to the packing of goods of Class 2, 6.2 and 7. Refer to 4.1.6 (Class 2), 4.1.8 (Class 6.2), 4.1.9 (Class 7) and to the applicable packing instruction in 4.1.4.
4.1.1.1. Dangerous goods shall be packed in good quality packagings, including IBCs and large packagings, which shall be strong enough to withstand the shocks and loadings normally encountered during carriage, including trans-shipment between means of transport and/or warehouses as well as any removal from a pallet or overpack for subsequent manual or mechanical handling. Packagings, including IBCs and large packagings, shall be constructed and closed so as to prevent any loss of contents when prepared for transport which might be caused under normal conditions of transport, by vibration, or by changes in temperature, humidity or pressure (resulting from altitude, for example). No dangerous residue shall adhere to the outside of packagings, IBCs and large packagings during carriage. These requirements apply, as appropriate, to new, reused, reconditioned or remanufactured packagings and to new and reused IBCs and large packagings.
4.1.1.2. Parts of packagings, including IBCs and large packagings, which are in direct contact with dangerous goods:
(a) shall not be affected or significantly weakened by those dangerous goods; and
(b) shall not cause a dangerous effect e.g. catalysing a reaction or reacting with the dangerous goods.
Where necessary, they shall be provided with a suitable inner coating or treatment.
4.1.1.3. Unless otherwise required in this Directive, each packaging, including IBCs and large packagings, except inner packagings, shall conform to a design type successfully tested in accordance with the requirements of 6.1.5, 6.5.4 or 6.6.5, respectively. The packagings for which the test is not required are listed in 6.1.1.3.
4.1.1.4. When filling packagings, including IBCs and large packagings, with liquids, sufficient ullage (outage) shall be left to ensure that neither leakage nor permanent distortion of the packaging occurs as a result of an expansion of the liquid caused by temperatures likely to occur during transport. Unless specific requirements are prescribed, liquids shall not completely fill a packaging at a temperature of 55 °C. However, sufficient ullage shall be left in an IBC to ensure that at the mean bulk temperature of 50 °C it is not filled to more than 98 % of its water capacity. For a filling temperature of 15 °C, the degree of filling shall be determined as follows, unless otherwise provided, either:
(a)
>TABLE>
or
(b) degree of filling
>PIC FILE= "L_2004121EN.053601.TIF">
of the capacity of the packaging.
In this formula α represents the mean coefficient of cubic expansion of the liquid substance between 15 °C and 50 °C; that is to say, for a maximum rise in temperature of 35 °C,
α is calculated according to the formula:
>PIC FILE= "L_2004121EN.053602.TIF">
d15 and d50 being the relative densities(21) of the liquid at 15 °C and 50 °C and tF the mean temperature of the liquid at the time of filling.
4.1.1.5. Inner packagings shall be packed in an outer packaging in such a way that, under normal conditions of carriage, they cannot break, be punctured or leak their contents into the outer packaging. Inner packagings that are liable to break or be punctured easily, such as those made of glass, porcelain or stoneware or of certain plastics materials, etc., shall be secured in outer packagings with suitable cushioning material. Any leakage of the contents shall not substantially impair the protective properties of the cushioning material or of the outer packaging.
4.1.1.6. Dangerous goods shall not be packed together in the same outer packaging or in large packagings, with dangerous or other goods if they react dangerously with each other (see definition of "dangerous reaction" in 1.2.1).
NOTE.
For mixed packing special requirements, see 4.1.10.
4.1.1.7. The closures of packagings containing wetted or diluted substances shall be such that the percentage of liquid (water, solvent or phlegmatizer) does not fall below the prescribed limits during transport.
4.1.1.7.1. Where two or more closure systems are fitted in series on an IBC, that nearest to the substance being carried shall be closed first.
4.1.1.8. Liquids may only be filled into inner packagings which have an appropriate resistance to internal pressure that may be developed under normal conditions of carriage. Where overpressure may develop in a package by the emission of gas from the contents (as a result of temperature increase or other cause), the packaging may be fitted with a vent, provided that the gas emitted will not cause danger on account of its toxicity, its flammability or the quantity released. A venting device shall be fitted if dangerous overpressure may develop due to normal decomposition of substances. The vent shall be so designed that, when the packaging is in the attitude in which it is intended to be carried, leakages of liquid and the penetration of foreign matter are prevented under normal conditions of carriage.
4.1.1.9. New, remanufactured or reused packagings, including IBCs and large packagings, or reconditioned packagings and repaired IBCs shall be capable of passing the tests prescribed in 6.1.5, 6.5.4 or 6.6.5 respectively. Before being filled and handed over for carriage, every packaging, including IBCs and large packagings, shall be inspected to ensure that it is free from corrosion, contamination or other damage and every IBC shall be inspected with regard to the proper functioning of any service equipment. Any packaging which shows signs of reduced strength as compared with the approved design type shall no longer be used or shall be so reconditioned, that it is able to withstand the design type tests. Any IBC which shows signs of reduced strength as compared with the tested design type shall no longer be used or shall be so repaired that it is able to withstand the design type tests.
4.1.1.10. Liquids shall be filled only into packagings, including IBCs, which have an appropriate resistance to the internal pressure that may develop under normal conditions of carriage. Packagings and IBCs marked with the hydraulic test pressure prescribed in 6.1.3.1(d) and 6.5.2.2.1 respectively shall be filled only with a liquid having a vapour pressure:
(a) such that the total gauge pressure in the packaging or IBC (i.e. the vapour pressure of the filling substance plus the partial pressure of air or other inert gases, less 100 kPa) at 55 °C, determined on the basis of a maximum degree of filling in accordance with 4.1.1.4 and a filling temperature of 15 °C, will not exceed two-thirds of the marked test pressure; or
(b) at 50 °C less than four-sevenths of the sum of the marked test pressure plus 100 kPa; or
(c) at 55 °C less than two-thirds of the sum of the marked test pressure plus 100 kPa.
Metal IBCs intended for the carriage of liquids shall not be used to carry liquids having a vapour pressure of more than 110kPa (1,1 bar) at 50 °C or 130kPa (1,3 bar) at 55 °C.
Examples of required marked test pressures for packagings, including IBCs, calculated as in 4.1.1.10 (c)
>TABLE>
NOTE 1.
For pure liquids the vapour pressure at 55 °C (Vp55) can often be obtained from scientific tables.
NOTE 2.
The table refers to the use of 4.1.1.10(c) only, which means that the marked test pressure shall exceed 1.5 times the vapour pressure at 55 °C less 100 kPa. When, for example, the test pressure for n-decane is determined according to 6.1.5.5.4 (a), the minimum marked test pressure may be lower.
NOTE 3.
For diethyl ether the required minimum test pressure under 6.1.5.5.5 is 250 kPa.
4.1.1.11. Empty packagings, including empty IBCs and empty large packagings, that have contained a dangerous substance are subject to the same requirements as those for a filled packaging, unless adequate measures have been taken to nullify any hazard.
4.1.1.12. Every packaging, including an IBC, intended to contain liquids shall successfully undergo a suitable leakproofness test, and be capable of meeting the appropriate test level indicated in 6.1.5.4.3 or 6.5.4.7 for the various types of IBCs:
(a) before it is first used for carriage;
(b) after remanufacturing or reconditioning of any packaging, before it is re-used for carriage;
(c) after the repair of any IBC, before it is re-used for carriage.
For this test the packaging, or IBC, need not have its closures fitted. The inner receptacle of a composite packaging or IBC may be tested witwood the outer packaging, provided the test results are not affected. This test is not necessary for
- inner packagings of combination packagings or large packagings,
- inner receptacles of composite packagings (glass, porcelain or stoneware), bearing the symbol "RID/ADR" in accordance with 6.1.3.1(a)(ii),
- light gauge metal packagings bearing the symbol "RID/ADR" in accordance with 6.1.3.1(a)(ii)
4.1.1.13. Packagings, including IBCs, used for solids which may become liquid at temperatures likely to be encountered during carriage shall also be capable of containing the substance in the liquid state.
4.1.1.14. Packagings, including IBCs, used for powdery or granular substances shall be sift-proof or shall be provided with a liner.
4.1.1.15. For plastics drums and jerricans, rigid plastics IBCs and composite IBCs with plastics inner receptacles, unless otherwise approved by the competent authority, the period of use permitted for the carriage of dangerous substances shall be five years from the date of manufacture, except where a shorter period of use is prescribed because of the nature of the substance to be carried.
4.1.1.16. Packages marked in accordance with 6.1.3 but which were approved in a State which is not a Member State may nevertheless be used for carriage under this Directive.
4.1.1.17. Use of salvage packagings
4.1.1.17.1 Damaged, defective or leaking packages containing dangerous goods, or dangerous goods that have spilled or leaked may be carried in salvage packagings in accordance with 6.1.5.1.11. This does not prevent the use of bigger size packagings of appropriate type and performance level under the conditions of 4.1.1.17.2.
4.1.1.17.2 Appropriate measures shall be taken to prevent excessive movement of the damaged or leaking packages within a salvage packaging. When the salvage packaging contains liquids, sufficient inert absorbent material shall be added to eliminate the presence of free liquid.
4.1.2. Additional general requirements for the use of IBC's
4.1.2.1. When IBCs are used for the carriage of liquids with a flash-point of 61 °C (closed cup) or lower, or of powders liable to dust explosion, measures shall be taken to prevent a dangerous electrostatic discharge.
4.1.2.2. The periodic testing and inspection requirements for IBCs are covered in Chapter 6.5. An IBC shall not be filled or handed over for carriage after the date of expiry of the periodic test required by 6.5.4.14.3, or the date of expiry of the periodic inspection required by 6.5.1.6.4. However, an IBC filled prior to the date of expiry of the periodic test or inspection may be carried for a period not to exceed three months beyond the date of expiry of the periodic test or inspection. In addition, an IBC may be carried after the date of expiry of the periodic test or inspection:
(a) after emptying but before cleaning, for purposes of performing the next required test or inspection prior to refilling; and
(b) unless otherwise specified by the competent authority, for a period not to exceed six months beyond the date of expiry of the last periodic test or inspection in order to allow the return of dangerous goods or residues for proper disposal or recycling.
NOTE.
For the information in the consignment note, see 5.4.1.1.11.
4.1.2.3. IBCs of type 31HZ2 shall be filled to at least 80 % of the volume of the outer casing and always be carried in covered wagons or closed containers.
4.1.3. General requirements concerning packing instructions
4.1.3.1. Packing Instructions applicable to dangerous goods of Classes 1 to 9 are listed in 4.1.4. They are subdivided into three sub-sections depending on the type of packagings to which they apply:
4.1.4.1 for packagings other than IBCs and large packagings; these Packing Instructions are designated by an alphanumeric code starting with the letter "R" for packagings specific to this Directive and Directive 94/55/EC;
4.1.4.2 for IBCs; these are designated by an alphanumeric code starting with the letters "IBC";
4.1.4.3 for large packagings; these are designated by an alphanumeric code starting with the letters "LP".
Generally, Packing Instructions specify that the general requirements of 4.1.1, 4.1.2 and/or 4.1.3, as appropriate, are applicable. They may also require compliance with the special requirements of 4.1.5, 4.1.6, 4.1.7, 4.1.8 or 4.1.9 when appropriate. Special packing requirements may also be specified in the packing instruction for individual substances or articles. They are also designated by an alphanumeric code comprising the letters:
"PP" for packagings other than IBCs and large packagings, or "RR" for special requirements specific to this Directive and Directive 94/55/EC;
"B" for IBCs;
"L" for large packagings.
Unless otherwise specified, each packaging shall conform to the applicable requirements of Part 6. Generally Packing Instructions do not provide guidance on compatibility and the user shall not select a packaging witwood checking that the substance is compatible with the packaging material selected (e.g. glass receptacles are unsuitable for most fluorides). Where glass receptacles are permitted in the packing instructions porcelain and stoneware packagings are also allowed.
4.1.3.2. Column (8) of Table A of Chapter 3.2 shows for each article or substance the Packing Instruction(s) that shall be used. Columns (9a) and (9b) indicate the special packing requirements and the mixed packing requirements (see 4.1.10) applicable to specific substances or articles.
4.1.3.3. Each packing instruction shows, where applicable, the acceptable single and combination packagings. For combination packagings, the acceptable outer packagings, inner packagings and when applicable the maximum quantity permitted in each inner or outer packaging, are shown. Maximum net mass and maximum capacity are as defined in 1.2.1.
4.1.3.4. The following packagings shall not be used when the substances being carried are liable to become liquid during carriage:
Packagings
Drums: 1D and 1G
Boxes: 4A, 4B, 4C1, 4C2, 4D, 4F, 4G, 4H1 and 4H2

Composite: 11HZ2, 21HZ2 and 31HZ2
For the purposes of this paragraph, substances and mixtures of substances having a melting point equal to or less than 45 °C shall be treated as solids liable to become liquid during carriage.
4.1.3.5. Where the packing instructions in this Chapter authorize the use of a particular type of outer packaging in a combination packaging (e.g. 4G), packagings bearing the same packaging identification code followed by the letters "V", "U" or "W" marked in accordance with the requirements of Part 6 (e.g. 4GV, 4GU or 4GW) may also be used under the same conditions and limitations applicable to the use of that type of outer packaging according to the relevant packing instructions. For example, a combination packaging marked with the packaging code "4GV" may be used whenever a combination packaging marked "4G" is authorized, provided the requirements in the relevant packing instruction regarding types of inner packagings and quantity limitations are respected.
4.1.3.6. Gas cylinders and gas receptacles approved by the competent authority are authorized for the carriage of any liquid or solid substance assigned to Packing Instruction P001 or P002 unless otherwise indicated in the Packing Instruction or by a special requirement in column (9a) of Table A of Chapter 3.2. The capacity of gas cylinders shall not exceed 450 litres. The capacity for gas receptacles shall not exceed 1000 litres.
4.1.3.7. Packagings or IBCs not specifically authorized in the applicable packing instruction shall not be used for the carriage of a substance or article unless specifically allowed under a temporary derogation agreed between Member States in accordance with 1.5.1.

4.1.5.1. The general provisions of section 4.1.1 shall be met.
4.1.5.2. All packagings for Class 1 goods shall be so designed and constructed that:
(a) They will protect the explosives, prevent them escaping and cause no increase in the risk of unintended ignition or initiation when subjected to normal conditions of carriage including foreseeable changes in temperature, humidity and pressure;
(b) The complete package can be handled safely in normal conditions of carriage; and
(c) The packages will withstand any loading imposed on them by foreseeable stacking to which they will be subject during carriage so that they do not add to the risk presented by the explosives, the containment function of the packagings is not harmed, and they are not distorted in a way or to an extent which will reduce their strength or cause instability of a stack.
4.1.5.3. All explosive substances and articles, as prepared for carriage, shall have been classified in accordance with the procedures detailed in 2.2.1.
4.1.5.4. Class 1 goods shall be packed in accordance with the appropriate Packing Instruction shown in Column 8 of Table A of Chapter 3.2, as detailed in 4.1.4.
4.1.5.5. Packagings, including IBCs and large packagings shall conform to the requirements of Chapter 6.1, 6.5 or 6.6, respectively, and shall meet the test requirements of 6.1.5, 6.5.4 or 6.6.5, respectively, for Packing Group II, subject to 4.1.1.13, 6.1.2.4 and 6.5.1.4.4. Packagings other than metal packagings meeting the test criteria of Packing Group I may be used. To avoid unnecessary confinement, metal packagings of Packing Group I shall not be used.
4.1.5.6. The closure device of packagings containing liquid explosives shall ensure a double protection against leakage.

4.1.5.11. Inner packagings, fittings and cushioning materials and the placing of explosive substances or articles in packages shall be accomplished in a manner which prevents the explosive substances or articles from becoming loose in the outer packaging under normal conditions of carriage. Metallic components of articles shall be prevented from making contact with metal packagings. Articles containing explosive substances not enclosed in an outer casing shall be separated from each other in order to prevent friction and impact. Padding, trays, partitioning in the inner or outer packaging, mouldings or receptacles may be used for this purpose.
4.1.5.12. Packagings shall be made of materials compatible with, and impermeable to, the explosives contained in the package, so that neither interaction between the explosives and the packaging materials, nor leakage, causes the explosive to become unsafe for carriage, or the hazard division or compatibility group to change.
4.1.5.13. The ingress of explosive substances into the recesses of seamed metal packagings shall be prevented.
4.1.5.14. Plastics packagings shall not be liable to generate or accumulate sufficient static electricity so that a discharge could cause the packaged explosive substances or articles to initiate, ignite or function.
4.1.5.15. Large and robust explosives articles, normally intended for military use, without their means of initiation or with their means of initiation containing at least two effective protective features, may be carried unpackaged. When such articles have propelling charges or are self-propelled, their ignition systems shall be protected against stimuli encountered during normal conditions of carriage. A negative result in Test Series 4 on an unpackaged article indicates that the article can be considered for carriage unpackaged. Such unpackaged articles may be fixed to cradles or contained in crates or other suitable handling, storage or launching devices in such a way that they will not become loose during normal conditions of carriage.
Where such large explosive articles are as part of their operational safety and suitability tests subjected to test regimes that meet the intentions of this Directive and such tests have been successfully undertaken, the competent authority may approve such articles to be carried under this Directive.
4.1.5.16. Explosive substances shall not be packed in inner or outer packagings where the differences in internal and external pressures, due to thermal or other effects, could cause an explosion or rupture of the package.
4.1.5.17. Whenever loose explosive substances or the explosive substance of an uncased or partly cased article may come into contact with the inner surface of metal packagings (1A2, 1B2, 4A, 4B and metal receptacles), the metal packaging shall be provided with an inner liner or coating (see 4.1.1.2).
4.1.5.18. Packing instruction P101 may be used for any explosive provided the packaging has been approved by a competent authority regardless of whether the packaging complies with the packing instruction assignment in column 8 of Table A of Chapter 3.2.

If the shell and service equipment are so constructed as to withstand impact or overturning it need not be protected in this way. Examples of such protection are given in 6.7.2.17.5.
4.2.1.3. Certain substances are chemically unstable. They are accepted for carriage only when the necessary steps have been taken to prevent their dangerous decomposition, transformation or polymerization during carriage. To this end, care shall in particular be taken to ensure that shells do not contain any substances liable to promote these reactions.
4.2.1.4. The temperature of the outer surface of the shell excluding openings and their closures or of the thermal insulation shall not exceed 70 °C during carriage. When dangerous goods are carried at elevated temperatures in either liquid or solid state, the shell shall be thermally insulated to meet this condition.
4.2.1.5. Empty portable tanks not cleaned and not gas-free shall comply with the same requirements as portable tanks filled with the previous substance.
4.2.1.6. Substances shall not be carried in the same or adjoining compartments of shells when they may react dangerously (see definition of dangerous reaction in 1.2.1) with each other.
4.2.1.7. The design approval certificate, the test report and the certificate showing the results of the initial inspection and test for each portable tank issued by the competent authority or its authorized body shall be retained by the authority or body and the owner. Owners shall be able to provide this documentation upon the request of any competent authority.
4.2.1.8. Unless the name of the substance(s) being carried appears on the metal plate described in 6.7.2.20.2, a copy of the certificate specified in 6.7.2.18.1 shall be made available upon the request of a competent authority or its authorized body and readily provided by the consignor, consignee or agent, as appropriate.
4.2.1.9. Degree of filling
4.2.1.9.1. Prior to filling, the filler shall ensure that the appropriate portable tank is used and that the portable tank is not loaded with substances which in contact with the materials of the shell, gaskets, service equipment and any protective linings, are likely to react dangerously with them to form dangerous products or appreciably weaken the material. The filler may need to consult the manufacturer of the substance in conjunction with the competent authority for guidance on the compatibility of the substance with the portable tank materials.
4.2.1.9.1.1 Portable tanks shall not be filled above the extent provided in 4.2.1.9.2 to 4.2.1.9.6.

>REFERENCE TO A GRAPHIC>
4.2.1.9.4. In these formulae, α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (tf) and the maximum mean bulk temperature during carriage (tr) (both in °C). For liquids carried under ambient conditions α could be calculated by the formula:
>REFERENCE TO A GRAPHIC>
in which d15 and d50 are the densities of the liquid at 15 °C and 50 °C, respectively.
4.2.1.9.4.1 The maximum mean bulk temperature (tr) shall be taken as 50 °C except that, for journeys under temperate or extreme climatic conditions, the competent authorities concerned may agree to a lower or require a higher temperature, as appropriate.
4.2.1.9.5. The requirements of 4.2.1.9.2 to 4.2.1.9.4.1 do not apply to portable tanks which contain substances maintained at a temperature above 50 °C during carriage (e.g. by means of a heating device). For portable tanks equipped with a heating device, a temperature regulator shall be used to ensure the maximum degree of filling is not more than 95 % at any time during carriage.
4.2.1.9.5.1 The maximum degree of filling (in %) for liquids carried under elevated temperature conditions is determined by the formula:

6.1.2.7. The following table indicates the codes to be used for designating types of packagings depending on the kind of packagings, the material used for their construction and their category; it also refers to the sub-sections to be consulted for the appropriate requirements:
>TABLE>
6.1.3. Marking
NOTES:
1. The marking indicates that the packaging which bears it corresponds to a successfully tested design type and that it complies with the requirements of this Chapter which are related to the manufacture, but not to the use, of the packaging. In itself, therefore, the mark does not necessarily confirm that the packaging may be used for any substance: generally the type of packaging (e.g. steel drum), its maximum capacity and/or mass, and any special requirements are specified for each substance in Table A of Chapter 3.2.
2. The marking is intended to be of assistance to packaging manufacturers, reconditioners, packaging users, carriers and regulatory authorities. In relation to the use of a new packaging, the original marking is a means for its manufacturer(s) to identify the type and to indicate those performance test regulations that have been met.
3. The marking does not always provide full details of the test levels, etc., and these may need to be taken further into account, e.g. by reference to a test certificate, to test reports or to a register of successfully tested packagings. For example, a packaging having an X or Y marking may be used for substances to which a packing group having a lesser degree of danger has been assigned with the relevant maximum permissible value of the relative density(33) determined by taking into account the factor 1.5 or 2.25 indicated in the packaging test requirements in 6.1.5 as appropriate, i.e. Group I packaging tested for products of relative density 1.2 could be used as a Group II packaging for products of relative density 1.8 or a Group III packaging for products of relative density 2.7, provided of course that all the performance criteria can still be met with the higher relative density product.
6.1.3.1. Each packaging intended for use according to this Directive shall bear markings which are durable, legible and placed in a location and of such a size relative to the packaging as to be readily visible. For packages with a gross mass of more than 30 kg, the markings or a duplicate thereof shall appear on the top or on a side of the packaging. Letters, numerals and symbols shall be at least 12 mm high, except for packagings of 30 litres or 30 kg capacity or less, when they shall be at least 6 mm in height and for packagings of 5 litres or 5 kg or less when they shall be of an appropriate size.
The marking shall show:
(a) (i) The United Nations packaging symbol
>PIC FILE= "L_2004121EN.069801.TIF">
This shall not be used for any purpose other than certifying that a packaging complies with the relevant requirements in this Chapter. For embossed metal packagings the capital letters "UN" may be applied instead of the symbol; or
(ii) The symbol "RID/ADR" for packagings approved for rail transport as well as road transport.
For composite packagings (glass, porcelain or stoneware) and light gauge metal packagings, conforming to simplified conditions (see 6.1.1.3, 6.1.5.3.1 (e), 6.1.5.3.4 (c), 6.1.5.4, 6.1.5.5.1 and 6.1.5.6);
(b) The code designating the type of packaging according to 6.1.2;
(c) A code in two parts:
(i) a letter designating the packing group(s) for which the design type has been successfully tested:
X for packing groups I, II and III;
Y for packing groups II and III;
Z for packing group III only;
(ii) the relative density, rounded off to the first decimal, for which the design type has been tested for packagings without inner packagings intended to contain liquids; this may be omitted when the relative density does not exceed 1.2. For packagings intended to contain solids or inner packagings, the maximum gross mass in kilograms.
For light-gauge metal packagings, marked with the symbol "RID/ADR" according to 6.1.3.1 (a)(ii) intended to contain substances having a viscosity at 23 °C exceeding 200 mm2/s, the maximum gross mass in kg;
(d) Either the letter "S" denoting that the packaging is intended for the carriage of solids or inner packagings or, for packagings (other than combination packagings) intended to contain liquids, the hydraulic test pressure which the packaging was shown to withstand in kPa rounded down to the nearest 10 kPa.
For light-gauge metal packagings, marked with the symbol "RID/ADR, according to" 6.1.3.1(a)(ii) intended to contain liquids having a viscosity at 23 °C exceeding 200 mm2/s, the letter "S";
NOTE:
The requirements of subparagraph (d) do not apply to packagings intended for the carriage of substances classified under UN Nos. 2814 or 2900 of Class 6.2.
(e) The last two digits of the year during which the packaging was manufactured. Packagings of types lH and 3H shall also be appropriately marked with the month of manufacture; this may be marked on the packaging in a different place from the remainder of the marking. An appropriate method is:
>PIC FILE= "L_2004121EN.069802.TIF">
(f) Requirements for the construction of packagings and the tests to which they will be submitted sign for motor vehicles in international traffic(34);
(g) The name of the manufacturer or other identification of the packaging specified by the competent authority.
6.1.3.2. Every reusable packaging liable to undergo a reconditioning process which might obliterate the packaging markings shall bear the marks indicated in 6.1.3.1 (a) to (e) in a permanent form. Marks are permanent if they are able to withstand the reconditioning process (e.g. embossed). For packagings other than metal drums of a capacity greater than 100 litres, these permanent marks may replace the corresponding durable markings prescribed in 6.1.3.1.
6.1.3.2.1. In addition to the durable markings prescribed in 6.1.3.1, every new metal drum of a capacity greater than 100 litres shall bear the marks described in 6.1.3.1 (a) to (e) on the bottom, with an indication of the nominal thickness of at least the metal used in the body (in mm, to 0,1 mm), in permanent form. When the nominal thickness of either head of a metal drum is thinner than that of the body, the nominal thickness of the top head, body, and bottom head shall be marked on the bottom in permanent form (e.g. embossed), for example "1.0-1.2-1.0" or "0.9-1.0-1.0". Nominal thickness of metal shall be determined according to the appropriate ISO standard, for example ISO 3574:1986 for steel. The marks indicated in 6.1.3.1 (f) and (g) shall not be applied in a permanent form except as provided in 6.1.3.2.3.
6.1.3.2.2. For remanufactured metal drums, if there is no change to the packaging type and no replacement or removal of integral structural components, the required markings need not be permanent. Every other remanufactured metal drum shall bear the markings in 6.1.3.1 to (e) in a permanent form on the top head or side.
6.1.3.2.3. Metal drums made from materials (e.g. stainless steel) designed to be reused repeatedly may bear the markings indicated in 6.1.3.1 (f) and (g) in a permanent form (e.g. embossed).
6.1.3.2.4. The marking in accordance with 6.1.3.1 is valid for only one design type or series of design types. Different surface treatments may fall within the same design type.
A "series of design types" means packagings of the same structural design, wall thickness, material and cross-section, which differ only in their lesser design heights from the design type approved.
The closures of receptacles shall be identifiable as those referred to in the test report.
6.1.3.3. Marking shall be applied in the sequence of the subparagraphs in 6.1.3.l (for examples, see 6.1.3.7). Any additional markings authorized by a competent authority shall still enable the parts of the mark to be correctly identified with reference to 6.1.3.l.
6.1.3.4. After reconditioning a packaging, the reconditioner shall apply to it a durable marking showing, in the following sequence:
(h) The State in which the reconditioning was carried out, indicated by the distinguishing sign for motor vehicles in international traffic (1);
(i) The name or authorized symbol of the reconditioner;
(j) The year of reconditioning; the letter "R"; and, for every packaging successfully passing the leakproofness test in 6.1.1.3, the additional letter "L".
6.1.3.5. When, after reconditioning, the markings required by 6.1.3.1 (a) to (d) no longer appear on the top head or the side of a metal drum, the reconditioner also shall apply them in a durable form followed by 6.1.3.4 (h), (i) and (j). These markings shall not identify a greater performance capability than that for which the original design type had been tested and marked.
6.1.3.6. Packagings manufactured with recycled plastics material as defined in 1.2.1 shall be marked "REC". This mark shall be placed near the mark prescribed in 6.1.3.1.

6.1.5.1.1. The design type of each packaging shall be tested as provided in 6.1.5 in accordance with procedures established by the competent authority.
6.1.5.1.2. Tests shall be successfully performed on each packaging design type before such packaging is used. A packaging design type is defined by the design, size, material and thickness, manner of construction and packing, but may include various surface treatments. It also includes packagings which differ from the design type only in their lesser design height.
6.1.5.1.3. Tests shall be repeated on production samples at intervals established by the competent authority. For such tests on paper or fibreboard packagings, preparation at ambient conditions is considered equivalent to the requirements of 6.1.5.2.3.
6.1.5.1.4. Tests shall also be repeated after each modification which alters the design, material or manner of construction of a packaging.
6.1.5.1.5. The competent authority may permit the selective testing of packagings that differ only in minor respects from a tested type, e.g. smaller sizes of inner packagings or inner packagings of lower net mass; and packagings such as drums, bags and boxes which are produced with small reductions in external dimension(s).
6.1.5.1.6. Where an outer packaging of a combination packaging has been successfully tested with different types of inner packagings, a variety of such different inner packagings may also be assembled in this outer packaging. In addition, provided an equivalent level of performance is maintained, the following variations in inner packagings are allowed without further testing of the package:
(a) Inner packagings of equivalent or smaller size may be used provided:
(i) the inner packagings are of similar design to the tested inner packagings (e.g. shape - round, rectangular, etc.);
(ii) the material of construction of the inner packagings (glass, plastics, metal, etc.) offers resistance to impact and stacking forces equal to or greater than that of the originally tested inner packaging;
(iii) the inner packagings have the same or smaller openings and the closure is of similar design (e.g. screw cap, friction lid, etc.);
(iv) sufficient additional cushioning material is used to take up void spaces and to prevent significant movement of the inner packagings;
(v) inner packagings are oriented within the outer packaging in the same manner as in the tested package.
(b) A lesser number of the tested inner packagings, or of the alternative types of inner packagings identified in (a) above, may be used provided sufficient cushioning is added to fill the void space(s) and to prevent significant movement of the inner packagings.
6.1.5.1.7. Articles or inner packagings of any type for solids or liquids may be assembled and carried without testing in an outer packaging under the following conditions:
(a) The outer packaging shall have been successfully tested in accordance with 6.1.5.3 with fragile (e.g. glass) inner packagings containing liquids using the packing group I drop height;
(b) The total combined gross mass of inner packagings shall not exceed one half the gross mass of inner packagings used for the drop test in (a) above;
(c) The thickness of cushioning material between inner packagings and between inner packagings and the outside of the packaging shall not be reduced below the corresponding thicknesses in the originally tested packaging; and if a single inner packaging was used in the original test, the thicknesses of cushioning between inner packagings shall not be less than the thickness of cushioning between the outside of the packaging and the inner packaging in the original test. If either fewer or smaller inner packagings are used (as compared to the inner packagings used in the drop test), sufficient additional cushioning material shall be used to take up void spaces;
(d) The outer packaging shall have passed successfully the stacking test in 6.1.5.6 while empty. The total mass of identical packages shall be based on the combined mass of inner packagings used for the drop test in (a) above;
(e) Inner packagings containing liquids shall be completely surrounded with a sufficient quantity of absorbent material to absorb the entire liquid contents of the inner packagings;
(f) If the outer packaging is intended to contain inner packagings for liquids and is not leakproof, or is intended to contain inner packagings for solids and is not siftproof, a means of containing any liquid or solid contents in the event of leakage shall be provided in the form of a leakproof liner, plastics bag or other equally efficient means of containment. For packagings containing liquids, the absorbent material required in above shall be placed inside the means of containing the liquid contents;
(g) Packagings shall be marked in accordance with 6.1.3 as having been tested to packing group I performance for combination packagings. The marked gross mass in kilograms shall be the sum of the mass of the outer packaging plus one half of the mass of the inner packaging(s) as used for the drop test referred to in (a) above. Such a packaging mark shall also contain a letter "V" as described in 6.1.2.4.
6.1.5.1.8. The competent authority may at any time require proof, by tests in accordance with this section, that serially-produced packagings meet the requirements of the design type tests. For verification purposes records of such tests shall be maintained.
6.1.5.1.9. If an inner treatment or coating is required for safety reasons, it shall retain its protective properties even after the tests.
6.1.5.1.10. Provided the validity of the test results is not affected and with the approval of the competent authority, several tests may be made on one sample.
6.1.5.1.11. Salvage packagings
Salvage packagings (see 1.2.1) shall be tested and marked in accordance with the requirements applicable to packing group II packagings intended for the carriage of solids or inner packagings, except as follows:
(a) The test substance used in performing the tests shall be water, and the packagings shall be filled to not less than 98 % of their maximum capacity. It is permissible to use additives, such as bags of lead shot, to achieve the requisite total package mass so long as they are placed so that the test results are not affected. Alternatively, in performing the drop test, the drop height may be varied in accordance with 6.1.5.3.4(b);
(b) Packagings shall, in addition, have been successfully subjected to the leakproofness test at 30 kPa, with the results of this test reflected in the test report required by 6.1.5.9;
(c) Packagings shall be marked with the letter "T" as described in 6.1.2.4.
6.1.5.2. Preparation of packagings for testing
6.1.5.2.1. Tests shall be carried out on packagings prepared as for carriage including, with respect to combination packagings, the inner packagings used. Inner or single receptacles or packagings shall be filled to not less than 98 % of their maximum capacity for liquids or 95 % for solids. For combination packagings where the inner packaging is designed to carry liquids and solids, separate testing is required for both liquid and solid contents. The substances or articles to be carried in the packagings may be replaced by other substances or articles except where this would invalidate the results of the tests. For solids, when another substance is used it shall have the same physical characteristics (mass, grain size, etc.) as the substance to be carried. It is permissible to use additives, such as bags of lead shot, to achieve the requisite total package mass, so long as they are placed so that the test results are not affected.
6.1.5.2.2. In the drop tests for liquids, when another substance is used, it shall be of similar relative density and viscosity to those of the substance being carried. Water may also be used for the liquid drop test under the conditions in 6.1.5.3.4.
6.1.5.2.3. Paper or fibreboard packagings shall be conditioned for at least 24 hours in an atmosphere having a controlled temperature and relative humidity (r.h.). There are three options, one of which shall be chosen. The preferred atmosphere is 23 ± 2 °C and 50 % ± 2 % r.h. The two other options are 20 ± 2 °C and 65 % ± 2 % r.h. or 27 ± 2 °C and 65 % ± 2 % r.h.
NOTE:
Average values shall fall within these limits. Short-term fluctuations and measurement limitations may cause individual measurements to vary by up to ±5 % relative humidity without significant impairment of test reproducibility.
6.1.5.2.4. Bung-type barrels made of natural wood shall be left filled with water for at least 24 hours before the tests.
6.1.5.2.5. To check that their chemical compatibility with the liquids is sufficient, plastics drums and jerricans in accordance with 6.1.4.8 and if necessary composite packagings (plastics material) in accordance with 6.1.4.19 shall be subjected to storage at ambient temperature for six months, during which time the test samples shall be kept filled with the goods they are intended to carry.
For the first and last 24 hours of storage, the test samples shall be placed with the closure downwards. However, packagings fitted with a vent shall be so placed on each occasion for five minutes only. After this storage the test samples shall undergo the tests prescribedin 6.1.5.3 to 6.1.5.6.
When it is known that the strength properties of the plastics material of the inner receptacles of composite packagings (plastics material) are not significantly altered by the action of the filling substance, it shall not be necessary to check that the chemical compatibility is sufficient.
A significant alteration in strength properties means:
(a) distinct embrittlement; or
(b) a considerable decrease in elasticity, unless related to a not less than proportionate increase in the elongation under load.
Where the behaviour of the plastics material has been established by other means, the above compatibility test may be dispensed with. Such procedures shall be at least equivalent to the above compatibility test and be recognized by the competent authority.
NOTE:
For plastics drums and jerricans and composite packagings (plastics material) made of high or average molecular mass polyethylene, see also 6.1.5.2.6 below.
6.1.5.2.6. For high molecular mass polyethylene drums and jerricans in accordance with 6.1.4.8 and if necessary composite packagings of high molecular mass polyethylene in accordance with 6.1.4.19, conforming to the following specifications:
- relative density at 23 °C after thermal conditioning for one hour at 100 °C >= 0,940, in accordance with ISO Standard 1183,
- melt flow rate at 190 °C/21,6 kg load <= 12 g/10 min, in accordance with ISO Standard 1133,
for jerricans in accordance with 6.1.4.8 of packing groups II and III and, if necessary, for composite packagings in accordance with 6.1.4.19 in average molecular mass polyethylene meeting the following specifications:
- relative density at 23 °C after thermal conditioning for one hour at 100 °C >= 0,940, in accordance with ISO Standard 1183,
- melt flow rate at 190 °C/2,160 kg load <= 0,5 g/10 min and >= 0,1g/10 min, in accordance with ISO Standard 1133,
- melt flow rate at 190 °C/5 kg load <= 3 g/10 min and >= 0,5 g/10 min, in accordance with ISO Standard 1133,
chemical compatibility with the liquids listed in 6.1.6.2 may be verified as follows with standard liquids (see 6.1.6.1).
The sufficient chemical compatibility of these packagings may be verified by storage for three weeks at 40 °C with the appropriate standard liquid; where this standard liquid is water, proof of chemical compatibility is not required.
For the first and last 24 hours of storage, the test samples shall be placed with the closure downwards. However, packagings fitted with a vent shall be so placed on each occasion for five minutes only. After this storage, the test samples shall undergo the tests prescribed in 6.1.5.3 to 6.1.5.6.
When a packaging design-type has satisfied the approval tests with a standard liquid, the comparable filling substances listed in 6.1.6.2 may be accepted for carriage without further testing, subject to the following conditions:
- the relative densities of the filling substances shall not exceed that used to determine the height for the drop test and the mass for the stacking test;
- the vapour pressures of the filling substances at 50 °C or 55 °C shall not exceed that used to determine the pressure for the internal pressure test.
The compatibility test for tert-Butyl hydroperoxide with more than 40 % peroxide content and peroxyacetic acids of Class 5.2, shall not be carried out using standard liquids. For these substances, proof of sufficient chemical compatibility of the test samples shall be provided during a storage period of six months at ambient temperature with the substances they are intended to carry.
The procedure in accordance with this paragraph also applies to high density, high or average molecular mass polyethylene packagings, the internal surface of which is fluorinated.
6.1.5.2.7. For drums and jerricans conforming to 6.1.4.8, and where necessary composite packagings conforming to 6.1.4.19, made of high or average molecular mass polyethylene, which have passed the test in 6.1.5.2.6, filling substances other than those listed in 6.1.6.2 may also be approved. Such approval shall be based on laboratory tests proving that the effect of such filling substances on the test specimens is less than that of the standard liquids. The processes of deterioration to be taken into account shall be the following: softening through swelling, cracking under stress and molecular degradation. The same conditions as those set out in 6.1.5.2.6 above shall apply with respect to relative density and vapour pressure.
6.1.5.2.8. Provided that the strength properties of the plastics inner packagings of a combination packaging are not significantly altered by the action of the filling substance, proof of chemical compatibility is not necessary. A significant alteration in strength properties means:
(a) distinct embrittlement;
(b) a considerable decrease in elasticity, unless related to a not less than proportionate increase in elastic elongation.
6.1.5.3. Drop test(35)
6.1.5.3.1. Number of test samples (per design type and manufacturer) and drop orientation.
For other than flat drops the centre of gravity shall be vertically over the point of impact.

6.3.1.2. Example of marking
>TABLE>
6.3.2. Test requirements for packagings
6.3.2.1. Other than for packagings for live animals and organisms, samples of each packaging shall be prepared for testing as described in 6.3.2.2 and then subjected to the tests in 6.3.2.4 to 6.3.2.6. If the nature of the packaging makes it necessary, equivalent preparation and tests are permitted, provided that these may be demonstrated to be at least as effective.
6.3.2.2. Samples of each packaging shall be prepared as for carriage, except that a liquid or solid infectious substance shall be replaced by water or, where conditioning at - 18 °C is specified, by water/antifreeze. Each primary receptacle shall be filled to 98 % capacity.
6.3.2.3. Tests required
>TABLE>
6.3.2.4. Packagings prepared as for carriage shall be subjected to the tests in 6.3.2.3, which - for test purposes - categorizes packagings according to their material characteristics. For outer packagings, the headings in the table relate to fibreboard or similar materials whose performance may be rapidly affected by moisture; plastics which may embrittle at low temperature; and other materials such as metal whose performance is not affected by moisture or temperature. If a primary receptacle and a secondary packaging, which together form an inner packaging, are made of different materials, the material of the primary receptacle determines the appropriate test. In instances where a primary receptacle is made of two materials, the material most liable to damage shall determine the appropriate tests.
6.3.2.5. (a) Samples shall be subjected to free-fall drops on to a rigid, non-resilient, flat, horizontal surface from a height of 9 m. Where the samples are in the shape of a box, five shall be dropped in sequence:
(i) one flat on to the base,
(ii) one flat on to the top,
(iii) one flat on to the long side,
(iv) one flat on to the short side,
(v) one on to a corner.
Where the samples are in the shape of a drum, three shall be dropped in sequence:
(vi) one diagonally on to the top chime, with the centre of gravity directly above the point of impact,
(vii) one diagonally on to the base chime,
(viii) one flat on to the side.
Following the appropriate drop sequence, there shall be no leakage from the primary receptacle(s) which shall remain protected by absorbent material in the secondary packaging.
NOTE:
While the sample shall be released in the required orientation, it is accepted that for aerodynamic reasons the impact may not take place in that orientation.
(b) The samples shall be subjected to a water spray that simulates exposure to rainfall of approximately 5 cm per hour for at least one hour. They shall then be subjected to the test described in (a).
(c) The samples shall be conditioned in an atmosphere of - 18 °C or less for a period of at least 24 hours and within 15 minutes of removal from that atmosphere be subjected to the test described in (a). Where the samples contain dry ice, the conditioning period may be reduced to 4 hours.
(d) Where the packaging is intended to contain dry ice, a test additional to that specified in (a) or (b) or (c) shall be carried out. One sample shall be stored so that all the dry ice dissipates and then be subjected to the test described in (a).

(a) Samples shall be placed on a level hard surface. A cylindrical steel rod with a mass of at least 7 kg, a diameter not exceeding 38 mm and whose impact end edges have a radius not exceeding 6 mm, shall be dropped in a vertical free fall from a height of 1 m, measured from the impact end to the impact surface of the sample. One sample shall be placed on its base. A second sample shall be placed in an orientation perpendicular to that used for the first. In each instance the steel rod shall be aimed to impact the primary receptacle(s). Following each impact, penetration of the secondary packaging is acceptable, provided that there is no leakage from the primary receptacle(s).

It shall have a diameter of 38 mm and the edges of the upper end a radius not exceeding 6 mm. The rod shall protrude from the surface a distance at least equal to that between the primary receptacle(s) and the outer surface of the outer packaging with a minimum of 200 mm. One sample shall be dropped in a vertical free fall from a height of 1 m, measured from the top of the steel rod. A second sample shall be dropped from the same height in an orientation perpendicular to that used for the first. In each instance, the packaging shall be so orientated that the steel rod could penetrate the primary receptacle(s). Following each impact, there shall be no leakage from the primary receptacle(s).
6.3.2.7. The competent authority may permit the selective testing of packagings that differ only in minor respects from a tested type, e.g. smaller sizes of inner packagings or inner packagings of lower net mass; and packagings such as drums, bags and boxes which are produced with small reductions in external dimension(s).
6.3.2.8. Provided an equivalent level of performance is maintained, the following variations in the primary receptacles placed within a secondary packaging are allowed without the need for further testing of the completed packaging:
(a) Primary receptacles of equivalent or smaller size as compared to the tested primary receptacles may be used provided:
(i) the primary receptacles are of similar design to the primary receptacle tested (e.g. shape: round, rectangular, etc.);
(ii) the material of construction of the primary receptacle (e.g. glass, plastics, metal etc.) offers resistance to impact and stacking forces equivalent to or better than that of the primary receptacle originally tested;
(iii) the primary receptacles have the same or smaller openings and the closure is of equivalent design (e.g. screw cap, friction lid, etc.);
(iv) sufficient additional cushioning material is used to take up empty spaces and to prevent significant movement of the primary receptacles; and
(v) primary receptacles are oriented within the secondary packagings in the same manner as in the tested package.
(b) A lesser number of the tested primary receptacles, or of the alternative types of primary receptacles identified in (a) above, may be used provided sufficient cushioning is added to fill the void space(s) and to prevent significant movement of the primary receptacles.
6.3.2.9. Inner receptacles of any type may be assembled within an intermediate (secondary) packaging and carried without testing in the outer packaging under the following conditions:
(a) The intermediate/outer packaging combination shall have been successfully tested in accordance with 6.3.2.5(a) with fragile (e.g. glass) inner receptacles;
(b) The total combined gross mass of inner receptacles shall not exceed one half the gross mass of inner receptacles used for the drop test in (a) above;
(c) The thickness of cushioning between inner receptacles and between inner receptacles and the outside of the intermediate packaging shall not be reduced below the corresponding thicknesses in the originally tested packaging; and if a single inner receptacle was used in the original test, the thickness of cushioning between inner receptacles shall not be less than the thickness of cushioning between the outside of the intermediate packaging and the inner receptacle in the original test. When either fewer or smaller inner receptacles are used (as compared to the inner receptacles used in the drop test), sufficient additional cushioning material shall be used to take up the void;
(d) The outer packaging shall have successfully passed the stacking test in 6.1.5.6 while empty. The total mass of identical packages shall be based on the combined mass of inner receptacles used in the drop test in (a) above;
(e) For inner receptacles containing liquids, an adequate quantity of absorbent material to absorb the entire liquid content of the inner receptacles shall be present;
(f) If the outer packaging is intended to contain inner receptacles for liquids and is not leakproof, or is intended to contain inner receptacles for solids and is not siftproof, a means of containing any liquid or solid contents in the event of leakage shall be provided in the form of a leakproof liner, plastics bag or other equally effective means of containment.

This certificate shall attest that the portable tank has been surveyed by that authority, is suitable for its intended purpose and meets the requirements of this Chapter and where appropriate the provisions for gases provided in portable tank instruction T50 in 4.2.4.2.6. When a series of portable tanks are manufactured without change in the design, the certificate shall be valid for the entire series. The certificate shall refer to the prototype test report, the gases allowed to be carried, the materials of construction of the shell and an approval number. The approval number shall consist of the distinguishing sign or mark of the State in whose territory the approval was granted, i.e. the distinguishing sign for use in international traffic, as prescribed by the Convention on Road Traffic, Vienna 1968, and a registration number. Any alternative arrangements according to 6.7.1.2 shall be indicated on the certificate.

Reference to this exemption shall be mentioned in the consignment note.
6.7.3.15.7. The exceptional test is necessary when the portable tank shows evidence of damaged or corroded areas, or leakage, or other conditions that indicate a deficiency that could affect the integrity of the portable tank. The extent of the exceptional test shall depend on the amount of damage or deterioration of the portable tank. It shall include at least the 2,5 year test according to 6.7.3.15.5.
6.7.3.15.8. The internal and external examinations shall ensure that:
(a) The shell is inspected for pitting, corrosion, or abrasions, dents, distortions, defects in welds or any other conditions, including leakage, that might render the portable tank unsafe for transport;

When the pressure test is a part of the test, the test pressure shall be the one indicated on the data plate of the portable tank. While under pressure, the portable tank shall be inspected for any leaks in the shell, piping or equipment.
6.7.3.15.10. In all cases when cutting, burning or welding operations on the shell have been effected, that work shall be to the approval of the competent authority or its authorized body taking into account the pressure vessel code used for the construction of the shell. A pressure test to the original test pressure shall be performed after the work is completed.
6.7.3.15.11. When evidence of any unsafe condition is discovered, the portable tank shall not be returned to service until it has been corrected and the pressure test is repeated and passed.
6.7.3.16. Marking
6.7.3.16.1. Every portable tank shall be fitted with a corrosion resistant metal plate permanently attached to the portable tank in a conspicuous place readily accessible for inspection.

>TABLE>
6.8.2.1.4. Shells shall be designed and constructed in accordance with the requirements of a technical code recognized by the competent authority, in which the material is chosen and the wall thickness determined taking into account maximum and minimum filling and working temperatures, but the following minimum requirements of 6.8.2.1.6 to 6.8.2.1.26 shall be met.
6.8.2.1.5. Tanks intended to contain certain dangerous substances shall be provided with additional protection. This may take the form of additional thickness of the shell (increased calculation pressure) determined in the light of the dangers inherent in the substances concerned or of a protective device (see the special provisions of 6.8.4).
6.8.2.1.6. Welds shall be skilfully made and shall afford the fullest safety. The execution and checking of welds shall comply with the requirements of 6.8.2.1.23.
6.8.2.1.7. Measures shall be taken to protect shells against the risk of deformation as a result of a negative internal pressure.

6.8.2.1.9. The materials of shells or of their protective linings which are in contact with the contents shall not contain substances liable to react dangerously (see "Dangerous reaction" in 1.2.1) with the contents, to form dangerous compounds, or substantially to weaken the material.
If contact between the substance carried and the material used for the construction of the shell entails a progressive decrease in the thickness of the walls, this thickness shall be increased at manufacture by an appropriate amount. This additional thickness to allow for corrosion shall not be taken into consideration in calculating the thickness of the shell walls.
6.8.2.1.10. For welded shells only materials of faultless weldability whose adequate impact strength at an ambient temperature of - 20 °C can be guaranteed, particularly in the weld seams and the zones adjacent thereto, shall be used.

If fine-grained steel is used, the guaranteed value of the yield stress Re shall not exceed 460 N/mm2 and the guaranteed value of the upper limit of tensile strength Rm shall not exceed 725 N/mm2, in accordance with the specifications of the material.
6.8.2.1.11. Ratios of Re/Rm exceeding 0,85 are not allowed for steels used in the construction of welded tanks.
Re= apparent yield stress for steels having a clearly-defined yield point or
guaranteed 0,2 % proof stress for steels with no clearly-defined yield point (1 % for austenitic steels)
Rm= tensile strength.
The values specified in the inspection certificate for the material shall be taken as a basis in determining this ratio in each case.
6.8.2.1.12. For steel, the elongation at fracture, in % shall be not less than
>PIC FILE= "L_2004121EN.082001.TIF">

A reservation shall be included in the certificate if it was not possible to investigate this compatibility exhaustively when the type approval was issued.
6.8.2.3.2. If the tanks, battery-wagons or MEGCs are manufactured in series without modification or according to the prototype, this approval shall be valid for the tanks, battery-wagons or MEGCs manufactured in series or according to the prototype.
A type approval may however serve for the approval of tanks with limited variations of the design that either reduce the loads and stresses on the tanks (e.g. reduced pressure, reduced mass, reduced volume) or increase the safety of the structure (e.g. increased wall thickness, more baffles, decreased diameter of openings). The limited variations shall be clearly described in the type approval certificate.

- internal liner,
- structural layer,
- external layer.
6.9.2.2.1. Requirements for fibre-reinforced plastics (FRP) tank-containers 6.9.2.2.1 The internal liner is the inner shell wall zone designed as the primary barrier to provide for the long-term chemical resistance in relation to the substances to be carried, to prevent any dangerous reaction with the contents or the formation of dangerous compounds and any substantial weakening of the structural layer owing to the diffusion of products through the internal liner.
The internal liner may either be a FRP liner or a thermoplastic liner.
6.9.2.2.2. FRP liners shall consist of:
(a) surface layer ("gel-coat"): adequate resin rich surface layer, reinforced with a veil, compatible with the resin and contents. This layer shall have a fibre mass content of not more than 30 % and have a thickness between 0,25 and 0,60 mm;
(b) strengthening layer(s): layer or several layers with a minimum thickness of 2 mm, containing a minimum of 900 g/m2 of glass mat or chopped fibres with a mass content in glass of not less than 30 % unless equivalent safety is demonstrated for a lower glass content.
6.9.2.2.3. Thermoplastic liners shall consist of thermoplastic sheet material as referred to in 6.9.2.3.4, welded together in the required shape, to which the structural layers are bonded. Durable bonding between liners and the structural layer shall be achieved by the use of an appropriate adhesive.
NOTE:
For the carriage of flammable liquids the internal layer may require additional measures in accordance with 6.9.2.14, in order to prevent the accumulation of electrical charges.
6.9.2.2.4. The structural layer of the shell is the zone specially designed according to 6.9.2.4 to 6.9.2.6 to withstand the mechanical stresses. This part normally consists of several fibre reinforced layers in determined orientations.
6.9.2.2.5. The external layer is the part of the shell which is directly exposed to the atmosphere. It shall consist of a resin rich layer with a thickness of at least 0,2 mm. For a thickness larger than 0,5 mm, a mat shall be used. This layer shall have a mass content in glass of less than 30 % and shall be capable of withstanding exterior conditions, in particular the occasional contact with the substance to be carried. The resin shall contain fillers or additives to provide protection against deterioration of the structural layer of the shell by ultra-violet radiation.
6.9.2.3. Raw materials
6.9.2.3.1. All materials used for the manufacture of FRP tank-containers shall be of known origin and specifications.
6.9.2.3.2. Resins
The processing of the resin mixture shall be carried out in strict compliance with the recommendations of the supplier. This concerns mainly the use of hardeners, initiators and accelerators. These resins can be:

For the internal surface liner, glass fibres of type C according to ISO 2078:1993 may be used. Thermoplastic veils may only be used for the internal liner when their compatibility with the intended contents has been demonstrated.
6.9.2.3.4. Thermoplastic liner material
Thermoplastic liners, such as unplastified polyvinyl chloride (PVC-U), polypropylene (PP), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), etc. may be used as lining materials.
6.9.2.3.5. Additives
Additives necessary for the treatment of the resin, such as catalysts, accelerators, hardeners and thixotropic substances as well as materials used to improve the tank, such as fillers, colours, pigments etc. shall not cause weakening of the material, taking into account lifetime and temperature expectancy of the design.
6.9.2.4. Shells, their attachments and their service and structural equipment shall be designed to withstand without loss of contents (other than quantities of gas escaping through any degassing vents) during the design lifetime:
- the static and dynamic loads in normal conditions of carriage;
- the prescribed minimum loads as defined in 6.9.2.5 to 6.9.2.10.
6.9.2.5.
