REGULATION (EU) No 540/2014 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 16 April 2014

on the sound level of motor vehicles and of replacement silencing systems, and amending Directive 2007/46/EC and repealing Directive 70/157/EEC

(Text with EEA relevance)

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty on the Functioning of the European Union, and in particular Article 114 thereof,

Having regard to the proposal from the European Commission,

After transmission of the draft legislative act to the national parliaments,

Having regard to the opinion of the European Economic and Social Committee (1),

Acting in accordance with the ordinary legislative procedure (2),

Whereas:

(1)

In accordance with Article 26(2) of the Treaty on the Functioning of the European Union (TFEU), the internal market comprises an area without internal frontiers in which the free movement of goods, persons, services and capital is to be ensured. To that end, a comprehensive EU type-approval system for motor vehicles is in place. The technical requirements for the EU type-approval of motor vehicles and their silencing systems with regard to permissible sound levels should be harmonised to avoid the adoption of requirements that differ from one Member State to another, and to ensure the proper functioning of the internal market while, at the same time, providing for a high level of environmental protection and public safety, a better quality of life and health, and taking account of road vehicles as a significant source of noise in the transport sector.

(2)

EU type-approval requirements already apply in the context of Union law regulating various aspects of the performance of motor vehicles, such as CO2 emissions from cars and light commercial vehicles, pollutant emissions and safety standards. The technical requirements applicable pursuant to this Regulation should be developed in a way that ensures a consistent approach throughout that Union law, taking into account all relevant noise factors.

(3)

Traffic noise harms health in numerous ways. Protracted noise-related stress can exhaust human physical reserves, disrupt the regulatory capacity of organ functions and hence limit their effectiveness. Traffic noise is a potential risk factor for the development of medical conditions and incidents such as high blood pressure and heart attacks. The effects of traffic noise should be further researched in the same manner as provided for in Directive 2002/49/EC of the European Parliament and of the Council (3).

(4)

Council Directive 70/157/EEC (4) harmonised the different technical requirements of Member States relating to the permissible sound level of motor vehicles and of their exhaust systems for the purpose of the establishment and operation of the internal market. For the purposes of the proper functioning of the internal market and in order to ensure a uniform and consistent application throughout the Union, it is appropriate to replace that Directive by this Regulation.

(5)	This Regulation constitutes a separate Regulation in the context of the type-approval procedure under Directive 2007/46/EC of the European Parliament and of the Council (5). Accordingly, Annexes IV, VI and XI to that Directive should be amended.

(6)

Directive 70/157/EEC refers to Regulation No 51 of the United Nations Economic Commission for Europe (UNECE) on noise emissions (6), which specifies the test method for noise emissions, and to UNECE Regulation No 59 on uniform provisions concerning the approval of replacement silencing systems (7). As a Contracting Party to the Agreement of UNECE of 20 March 1958 concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (8), the Union has decided to apply those Regulations.

(7)

Since its adoption, Directive 70/157/EEC has been substantially amended several times. The most recent reduction of sound level limits for motor vehicles, introduced in 1995, did not have the effects expected. Studies showed that the test method used under that Directive no longer reflected real life driving behaviour in urban traffic. In particular, as pointed out in the Green Paper on the Future Noise Policy of 4 November 1996, the contribution of tyre-rolling noise to total noise emissions was underestimated in the test method.

(8)

This Regulation should therefore introduce a different test method from that laid down in Directive 70/157/EEC. The new method should be based on the test method published by the UNECE Working Party on Noise (GRB) in 2007 which incorporated a 2007 version of the standard ISO 362. The results of monitoring of both the old and the new test methods were submitted to the Commission.

(9)

The new test method is considered to be representative for sound levels during normal traffic conditions, but it is less representative for sound levels under worst case conditions. Therefore, it is necessary to lay down in this Regulation additional sound emission provisions. Those provisions should establish preventive requirements intended to cover driving conditions of the vehicle in real traffic outside the type-approval driving cycle and to prevent cycle beating. Those driving conditions are environmentally relevant and it is important to ensure that the sound emission of a vehicle under street-driving conditions does not differ significantly from what can be expected from the type-approval test result for the specific vehicle.

(10)

This Regulation should also further reduce sound level limits. It should take account of the new stricter noise requirements for motor vehicle tyres laid down in Regulation (EC) No 661/2009 of the European Parliament and of the Council (9). Studies highlighting the annoyance and adverse health effects resulting from road traffic noise and the associated costs and benefits should also be taken into account.

(11)	The overall limit values should be reduced with regard to all noise sources of motor vehicles including the air intake over the power train and the exhaust, taking into account the tyre contribution to noise reduction referred to in Regulation (EC) No 661/2009.

(12)	Chapter III of Regulation (EC) No 765/2008 of the European Parliament and of the Council (10), in accordance with which Member States are required to carry out market surveillance and control products entering the Union market, applies to the products covered by this Regulation.

(13)

Noise is a multifaceted issue with multiple sources and factors that influence the sound perceived by people and the impact of that sound upon them. Vehicle sound levels are partially dependent on the environment in which the vehicles are used, in particular the quality of the road infrastructure, and therefore a more integrated approach is required. Directive 2002/49/EC requires strategic noise maps to be drawn up periodically as regards, inter alia, major roads. The information presented in those maps could form the basis of future research work regarding environmental noise in general, and road surface noise in particular, as well as best practice guides on technological road quality development and a classification of road surface types, if appropriate.

(14)

The Sixth Community Environment Action Programme (11) set out the framework for environmental policy-making in the Union for the period 2002-2012. That programme called for actions in the field of noise pollution to substantially reduce the number of people regularly affected by long-term average levels of noise, particularly from traffic.

(15)

Technical measures to reduce the sound level of motor vehicles have to comply with a set of competing requirements, such as those of reducing noise and pollutant emissions and improving safety whilst keeping the vehicle in question as cheap and efficient as possible. In attempting to comply with all those requirements equally and strike a balance between them, the vehicle industry all too often runs up against the limits of what is currently technically feasible. Vehicle designers have repeatedly managed to push those limits back by using new, innovative materials and methods. Union law should set a clear framework for innovation that can be achieved in a realistic timeframe. This Regulation establishes such a framework and thus provides an immediate incentive for innovation in keeping with the needs of society, whilst in no way restricting the economic freedom that is vital to the industry.

(16)

Noise pollution is primarily a local problem, but one which calls for a Union-wide solution. The first step in any sustainable noise emissions policy should be to devise measures to reduce sound levels at source. Since the target of this Regulation is the noise source that motor vehicles represent, and given that that noise source is by definition a mobile one, national measures alone are not sufficient.

(17)

The provision of information on sound emissions to consumers and public authorities has the potential to influence purchasing decisions and accelerate the transition to a quieter vehicle fleet. Accordingly, manufacturers should provide information on sound levels of vehicles at the point of sale and in technical promotional material. A label, comparable to the labels used for information on CO2 emissions, fuel-consumption and tyre-noise, should inform consumers about the sound emissions of a vehicle. The Commission should undertake an impact assessment on the labelling conditions applicable to air and noise pollution levels and on consumer information. That impact assessment should take into account the different types of vehicles covered by this Regulation (including pure electric vehicles) as well as the effect that such labelling could have on the vehicle industry.

(18)	In order to reduce road traffic noise, public authorities should be able to put in place measures and incentives to encourage the use of quieter vehicles.

(19)

Environmental benefits from hybrid electric and pure electric vehicles have resulted in a substantial reduction of the noise emitted by such vehicles. That reduction has removed an important source of an audible signal that is relied upon by blind and visually impaired pedestrians and cyclists, amongst other road users, to become aware of the approach, presence or departure of those vehicles. As a consequence, industry is developing Acoustic Vehicle Alerting Systems (AVAS) to compensate for this lack of audible signal in hybrid electric and pure electric vehicles. The performance of such AVAS fitted to vehicles should be harmonised. In developing of those AVAS consideration should be given to the overall impact on noise in communities.

(20)

The Commission should examine the potential of active safety systems in more silent vehicles such as hybrid electric and pure electric vehicles in order to better serve the objective of improving the safety of vulnerable road users in urban areas, such as blind, visually impaired and aurally challenged pedestrians, cyclists and children.

(21)

Vehicle sound levels have a direct impact on the quality of life of Union citizens, in particular in urban areas in which there is little or no electric or underground public transport provision or cycling or walking infrastructure. The target of doubling the number of public transport users that the European Parliament set in its resolution of 15 December 2011 on the Roadmap to a Single European Transport Area - Towards a competitive and resource efficient transport system (12) should also be taken into account. The Commission and the Member States should, in accordance with the subsidiarity principle, promote public transport, walking and cycling, with a view to reducing noise pollution in urban areas.

(22)

A vehicle's sound level is partially dependent on how it is used and how well it is maintained following its purchase. Therefore, steps should be taken to raise public awareness in the Union of the importance of adopting a smooth driving style and keeping within the speed limits in force in each Member State.

(23)	In order to simplify the type-approval legislation of the Union, in line with the 2007 recommendations of the CARS 21 Report, it is appropriate to base this Regulation on UNECE Regulations No 51, with regard to the test method, and No 59 with regard to replacement silencing systems.

(24)

To enable the Commission to adapt certain requirements of Annexes I, IV, VIII and X to this Regulation to technical progress, the power to adopt acts in accordance with Article 290 TFEU should be delegated to the Commission in respect of the amendment of the provisions in those Annexes related to the test methods and sound levels. It is of particular importance that the Commission carry out appropriate consultations during its preparatory work, including at expert level. The Commission, when preparing and drawing up delegated acts, should ensure a simultaneous, timely and appropriate transmission of relevant documents to the European Parliament and to the Council.

(25)

Since the objective of this Regulation, namely to lay down administrative and technical requirements for the EU type-approval of all new vehicles with regard to their sound level and of replacement silencing systems and components thereof type-approved as separate technical units and intended for those vehicles, cannot be sufficiently achieved by the Member States but can rather, by reason of its scale and effects, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. In accordance with the principle of proportionality as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve that objective.

(26)	As a consequence of the application of the new regulatory framework laid down pursuant to this Regulation, Directive 70/157/EEC should be repealed,

HAVE ADOPTED THIS REGULATION:

ANNEX II

METHODS AND INSTRUMENTS FOR MEASURING THE NOISE MADE BY MOTOR VEHICLES

1.

METHODS OF MEASUREMENT

1.1. The noise made by the vehicle type submitted for EU type-approval shall be measured by the two methods described in this Annex for the vehicle in motion and for the vehicle when stationary. In the case of a hybrid electric vehicle where an internal combustion engine cannot operate when the vehicle is stationary, the emitted noise shall only be measured in motion.

Vehicles having a technically permissible maximum laden mass exceeding 2800 kg shall be subjected to an additional measurement of the compressed air noise with the vehicle stationary in accordance with the specifications of Annex V, if the corresponding brake equipment is part of the vehicle.

1.2. The values measured in accordance with the tests set out in point 1.1 of this Annex shall be entered in the test report and on a form conforming to the model contained in Appendix 2 to Annex I.

2.

MEASURING INSTRUMENTS

2.1. Acoustic measurements

The apparatus used for measuring the sound level shall be a precision sound-level meter or equivalent measurement system meeting the requirements of class 1 instruments (inclusive of the recommended windscreen, if used). Those requirements are described in ‘IEC 61672-1:2002: Precision sound level meters’, second edition, of the International Electrotechnical Commission (IEC).

Measurements shall be carried out using the ‘fast’ response of the acoustic measurement instrument and the ‘A’ weighting curve also described in ‘IEC 61672-1:2002’. When using a system that includes a periodic monitoring of the A-weighted sound pressure level, a reading shall be made at a time interval not greater than 30 ms (milliseconds).

The instruments shall be maintained and calibrated in accordance with the instructions of the instrument manufacturer.

2.2. Compliance with requirements

Compliance of the acoustic measurement instrumentation shall be verified by the existence of a valid certificate of compliance. A certificate of compliance shall be deemed to be valid if certification of compliance with the standards was conducted within the previous 12-month period for the sound calibration device and within the previous 24-month period for the instrumentation system. All compliance testing shall be conducted by a laboratory, which is authorised to perform calibrations traceable to the appropriate standards.

2.3. Calibration of the entire Acoustic Measurement System for measurement session

At the beginning and at the end of every measurement session, the entire acoustic measurement system shall be checked by means of a sound calibrator that complies with the requirements for sound calibrators of precision class 1 as set out in IEC 60942: 2003. Without any further adjustment the difference between the readings shall be less than or equal to 0,5 dB. If that value is exceeded, the results of the measurements obtained after the previous satisfactory check shall be discarded.

2.4. Instrumentation for speed measurements

The engine speed shall be measured with instrumentation having an accuracy of ± 2 % or better at the engine speeds required for the measurements being performed.

The road speed of the vehicle shall be measured with instrumentation having an accuracy of at least ± 0,5 km/h, when using continuous measurement devices.

If testing uses independent measurements of speed, this instrumentation shall meet specification limits of at least ± 0,2 km/h.

2.5. Meteorological instrumentation

The meteorological instrumentation used to monitor the environmental conditions during the test shall include the following devices, which meet at least the accuracies listed below:

—	temperature measuring device, ± 1 °C;

—	wind speed-measuring device, ± 1,0 m/s;

—	barometric pressure measuring device, ± 5 hPa;

—	a relative humidity measuring device, ± 5 %.

3.

CONDITIONS OF MEASUREMENT

3.1. Test Site and ambient conditions

3.1.1. The surface of the test track and the dimensions of the test site shall be in accordance with ISO 10844:2011. The surface of the site shall be free of powdery snow, tall grass, loose soil or cinders. There shall be no obstacle which could affect the sound field within the vicinity of the microphone and the sound source. The observer carrying out the measurements shall so position himself as not to affect the readings of the measuring instrument.

3.1.2. Measurements shall not be made under adverse weather conditions. It shall be ensured that the results are not affected by gusts of wind.

The meteorological instrumentation shall be positioned adjacent to the test area at a height of 1,2 m ± 0,02 m. The measurements shall be made when the ambient air temperature is between + 5 °C and + 40 °C.

The tests shall not be carried out if the wind speed, including gusts, at microphone height exceeds 5 m/s, during the noise measurement interval.

A value representative of temperature, wind speed and direction, relative humidity, and barometric pressure shall be recorded during the noise measurement interval.

Any noise peak which appears to be unrelated to the characteristics of the general sound level of the vehicle shall be ignored in taking the readings.

The background noise shall be measured for a duration of 10 seconds immediately before and after a series of vehicle tests. The measurements shall be made with the same microphones and microphone locations used during the test. The A-weighted maximum noise pressure level shall be reported.

The background noise (including any wind noise) shall be at least 10 dB below the A-weighted noise pressure level produced by the vehicle under test. If the difference between the ambient noise and the measured noise is between 10 and 15 dB(A), the appropriate correction shall be subtracted from the readings on the noise-level meter in order to calculate the test results, as in the following table:

Difference between ambient noise and noise to be measured dB(A)	10	11	12	13	14	15
Correction dB(A)	0,5	0,4	0,3	0,2	0,1	0,0

3.2. Vehicle

3.2.1. The vehicle tested shall be representative of vehicles to be put on the market and selected by the manufacturer in agreement with the technical service, to comply with the requirements of this Regulation. Measurements shall be made without any trailer, except in the case of non-separable vehicles. At the request of the manufacturer, measurements may be made on vehicles with lift axle(s) in a raised position.

Measurements shall be made on vehicles at the test mass mt specified in accordance with the following table:

Vehicle Category	Vehicle test mass (mt)
M1	mt = mro
N1	mt = mro
N2, N3	mt = 50 kg per kW rated engine power Extra loading to reach the test mass of the vehicle shall be placed above the driven rear axle(s). The extra loading is limited to 75 % of the technically permissible maximum laden mass allowed for the rear axle. The test mass shall be achieved with a tolerance of ± 5 %. If the centre of gravity of the extra loading cannot be aligned with the centre of the rear axle, the test mass of the vehicle shall not exceed the sum of the front axle and the rear axle load in unladen condition plus the extra loading. The test mass for vehicles with more than two axles shall be the same as for a two-axle vehicle.
M2, M3	mt = mro — mass of the crew member (if applicable) or, if the tests are carried out on an incomplete vehicle not having bodywork, mt = 50 kg per kW rated engine power respectively in compliance with conditions above (see category N2, N3).

3.2.2. At the applicant's request, the vehicle of a category M2, M3, N2 or N3 shall be deemed representative of its completed type if the tests are carried out on an incomplete vehicle not having bodywork. In the test of an incomplete vehicle, all relevant soundproofing materials, panels and noise reduction components and systems shall be fitted on the vehicle as designed by the manufacturer except a part of bodywork which is built at a later stage.

No new test shall be required due to the fitting of a supplement fuel tank or re-location of the original fuel tank on the condition that other parts or structures of the vehicle apparently affecting sound emissions have not been altered.

3.2.3. Tyre rolling sound emissions are laid down in Regulation (EC) No 661/2009. The tyres to be used for the test shall be representative for the vehicle and shall be selected by the vehicle manufacturer and recorded in Addendum to Appendix 2 to Annex I to this Regulation. They shall correspond to one of the tyre sizes designated for the vehicle as original equipment. The tyre is or will be commercially available on the market at the same time as the vehicle (1). The tyres shall be inflated to the pressure recommended by the vehicle manufacturer for the test mass of the vehicle. The tyres shall have at least 1,6 mm tread depth.

3.2.4. Before the measurements are started, the engine shall be brought to its normal operating conditions.

3.2.5. If the vehicle is fitted with more than two-wheel drive, it shall be tested in the drive which is intended for normal road use.

3.2.6. If the vehicle is fitted with one or more fans having an automatic actuating mechanism, this system shall not be interfered with during the measurements.

3.2.7. If the vehicle is equipped with a silencing system containing fibrous materials, the exhaust system is to be conditioned before the test in accordance with Annex IV.

4.

METHODS OF TESTING

4.1. Measurement of noise of vehicles in motion

4.1.1. General test conditions

Two lines, AA' and BB', parallel to line PP' and situated respectively 10 m forward and 10 m rearward of line PP' shall be marked out on the test runway.

At least four measurements shall be made on each side of the vehicle and for each gear. Preliminary measurements may be made for adjustment purposes, but shall be disregarded.

The microphone shall be located at a distance of 7,5 m ± 0,05 m from the reference line CC' of the track and 1,2 m ± 0,02 m above the ground.

The reference axis for free field conditions (see IEC 61672-1:2002) shall be horizontal and directed perpendicularly towards the path of the vehicle line CC'.

4.1.2. Specific test conditions for vehicles

4.1.2.1. Vehicles of category M1, M2 ≤ 3 500 kg, N1

The path of the centreline of the vehicle shall follow line CC' as closely as possible throughout the entire test, from the approach to line AA' until the rear of the vehicle passes line BB'. If the vehicle is fitted with more than two-wheel drive, it shall be tested in the drive selection which is intended for normal road use.

If the vehicle is fitted with an auxiliary manual transmission or a multi-gear axle, the position used for normal urban driving shall be used. In all cases, the gear ratios for slow movements, parking or braking shall be excluded.

The test mass of the vehicle shall be that set out in the Table in point 3.2.1.

The test speed vtest is 50 km/h ± 1 km/h. The test speed shall be reached when the reference point is at line PP'.

4.1.2.1.1. Power to mass ratio index (PMR)

PMR is calculated using the following formula:

PMR = (Pn/mt) × 1 000 where Pn is measured in kW and mt is measured in kg in accordance with point 3.2.1 of this Annex.

PMR, with no dimension, is used for the calculation of acceleration.

4.1.2.1.2. Calculation of acceleration

Acceleration calculations are applicable to M1, N1 and M2 ≤ 3 500 kg categories only.

All accelerations are calculated using different speeds of the vehicle on the test track. The formulae given are used for the calculation of awot i, awot i+1 and awot test. The speed either at AA' or PP' is defined as the vehicle speed when the reference point passes AA' (vAA') or PP' (vPP'). The speed at BB' is defined when the rear of the vehicle passes BB' (vBB'). The method used for calculating the acceleration shall be indicated in the test report.

Due to the definition of the reference point for the vehicle, the length of the vehicle (lveh) is considered differently in the formula below. If the reference point is in the front of the vehicle, then l = lveh, mid: l = 1/2 lveh and rear: l = 0.

4.1.2.1.2.1 The calculation procedure for vehicles with manual transmission, automatic transmission, adaptive transmissions and continuous variable transmissions (CVTs) tested with locked gear ratios is as follows:

awot test = ((vBB'/3,6)2 – (vAA'/3,6)2)/(2*(20+l))

awot test used in the determination of gear selection shall be the average of the four awot test, i during each valid measurement run.

Pre-acceleration may be used. The point of depressing the accelerator before line AA' shall be reported in the test report.

4.1.2.1.2.2. The calculation procedure for vehicles with automatic transmissions, adaptive transmissions and CVTs tested with non-locked gear ratios is as follows:

awot test used in the determination of gear selection shall be the average of the four awot test, i during each valid measurement run.

Where devices or measures described in point 4.1.2.1.4.2 can be used to control transmission operation for the purpose of achieving test requirements, awot test shall be calculated using the following formula:

awot test = ((vBB'/3,6)2 – (vAA'/3,6)2)/(2*(20+l))

Pre-acceleration may be used:

Where devices or measures described in point 4.1.2.1.4.2 are not used, awot test shall be calculated using the following formula:

awot_testPP-BB = ((vBB'/3,6)2 – (vPP'/3,6)2)/(2*(10+l))

awot_test PP-BB : acceleration between point PP and BB

Pre-acceleration shall not be used.

The location of depressing the accelerator shall be where the reference point of the vehicle passes line AA'.

4.1.2.1.2.3 Target acceleration

The target acceleration a urban defines the typical acceleration in urban traffic and is derived from statistical investigations. It is a function depending on the PMR of a vehicle.

The target acceleration a urban shall be calculated using the following formula:

a urban = 0,63 * log10 (PMR) – 0,09

4.1.2.1.2.4. Reference acceleration

The reference acceleration awot ref defines the required acceleration during the acceleration test on the test track. It is a function depending on the PMR of a vehicle. That function is different for specific vehicle categories.

The reference acceleration awot ref shall be calculated using the following formula:

a wot ref = 1,59 * log10 (PMR) –1,41 for PMR ≥ 25

a wot ref = a urban = 0,63 * log10 (PMR) – 0,09 for PMR < 25

4.1.2.1.3. Partial power factor kP

The partial power factor kP (see point 4.1.3.1) is used for the weighted combination of the test results of the acceleration test and the constant speed test for vehicles of category M1 and N1.

In cases other than a single gear test, a wot ref shall be used instead of a wot test (see point 4.1.3.1).

4.1.2.1.4. Gear ratio selection

The selection of gear ratios for the test depends on their specific acceleration potential awot under full throttle condition, in accordance with the reference acceleration awot ref required for the full throttle acceleration test.

Some vehicles may have different software programs or modes for the transmission (e.g. sporty, winter, adaptive). Where the vehicle has different modes leading to valid accelerations, the vehicle manufacturer shall prove to the satisfaction of the technical service, that the vehicle is tested in the mode which achieves an acceleration closest to a wot ref.

4.1.2.1.4.1. Vehicles with manual transmissions, automatic transmissions, adaptive transmissions or CVTs tested with locked gear ratios

The following conditions for selection of gear ratios are possible:

(a)	if one specific gear ratio gives an acceleration in a tolerance band of ± 5 % of the reference acceleration awot ref, not exceeding 2,0 m/s2, test with that gear ratio.

(b)

if none of the gear ratios give the required acceleration, then choose a gear ratio i, with an acceleration higher and a gear ratio i + 1, with an acceleration lower than the reference acceleration. If the acceleration value in gear ratio i does not exceed 2,0 m/s2, use both gear ratios for the test. The weighting ratio in relation to the reference acceleration awot ref is calculated by:

k = (a wot ref – a wot (i+1))/(a wot (i) – a wot (i+1))

(c)

if the acceleration value of gear ratio i exceeds 2,0 m/s2, the first gear ratio that gives an acceleration below 2,0 m/s2 shall be used unless gear ratio i + 1 provides an acceleration less than aurban. In this case, two gears, i and i + 1 shall be used, including the gear i with the acceleration exceeding 2,0 m/s2. In other cases, no other gear shall be used. The achieved acceleration awot test during the test shall be used for the calculation of the partial power factor kP instead of awot ref.

(d)	if the vehicle has a transmission in which there is only one selection for the gear ratio, the acceleration test shall be carried out in this vehicle gear selection. The achieved acceleration is then used for the calculation of the partial power factor kP instead of awot ref.

(e)	if rated engine speed is exceeded in a gear ratio before the vehicle passes BB' the next higher gear shall be used.

4.1.2.1.4.2. Vehicles with automatic transmission, adaptive transmissions and CVTs tested with non-locked gear ratios

The gear selector position for full automatic operation shall be used.

The acceleration value awot test shall be calculated as defined in point 4.1.2.1.2.2.

The test may then include a gear change to a lower range and a higher acceleration. A gear change to a higher range and a lower acceleration is not allowed. A gear shifting to a gear ratio which is not used in urban traffic shall be avoided.

Therefore, it shall be permitted to establish and use electronic or mechanical devices, including alternate gear selector positions, to prevent a downshift to a gear ratio which is typically not used at the specified test condition in urban traffic.

The achieved acceleration awot test shall be greater or equal to aurban.

If possible, the manufacturer shall take measures to avoid an acceleration value awot test greater than 2,0 m/s2.

The achieved acceleration a wot test shall then be used for the calculation of the partial power factor kp (see point 4.1.2.1.3) instead awot ref.

4.1.2.1.5. Acceleration test

The manufacturer shall define the position of the reference point in front of line AA' of fully depressing the accelerator. The accelerator shall be fully depressed (as rapidly as is practicable) when the reference point of the vehicle reaches the defined point. The accelerator shall be kept in this depressed condition until the rear of the vehicle reaches line BB'. The accelerator shall then be released as rapidly as possible. The point of fully depressing the accelerator shall be reported in the test report. The technical service shall have the possibility of pre-testing.

In the case of articulated vehicles consisting of two non-separable units regarded as a single vehicle, the semi-trailer shall be disregarded in determining when line BB' is crossed.

4.1.2.1.6. Constant speed test

The constant speed test shall be carried out with the same gear(s) specified for the acceleration test and a constant speed of 50 km/h with a tolerance of ± 1 km/h between AA' and BB'. During the constant speed test, the acceleration control shall be positioned to maintain a constant speed between AA' and BB' as specified. If the gear is locked for the acceleration test, the same gear shall be locked for the constant speed test.

The constant speed test is not required for vehicles with a PMR < 25.

4.1.2.2. Vehicles of categories M2 > 3 500 kg, M3, N2, N3

The path of the centreline of the vehicle shall follow line CC' as closely as possible throughout the entire test, from the approach to line AA' until the rear of the vehicle passes line BB'. The test shall be conducted without a trailer or semi-trailer. If a trailer is not readily separable from the towing vehicle, the trailer shall not be taken into consideration when assessing the crossing of line BB'. If the vehicle incorporates equipment such as a concrete mixer, a compressor, etc., this equipment shall not be in operation during the test. The test mass of the vehicle shall be set out in the table set out in point 3.2.1.

Target conditions of category M2 > 3 500 kg, N2

When the reference point passes line BB', the engine speed nBB' shall be between 70 % and 74 % of speed S, at which the engine develops its rated maximum power, and the vehicle speed shall be 35 km/h ± 5 km/h. Between line AA' and line BB' a stable acceleration condition shall be ensured.

Target conditions of category M3, N3:

When the reference point passes line BB', the engine speed nBB' shall be between 85 % and 89 % of speed S, at which the engine develops its rated maximum power, and the vehicle speed shall be 35 km/h ± 5 km/h. Between line AA' and line BB' a stable acceleration condition shall be ensured.

4.1.2.2.1. Gear ratio selection

4.1.2.2.1.1. Vehicles with manual transmissions

Stable acceleration conditions shall be ensured. The gear choice shall be determined by the target conditions. If the difference in speed exceeds the given tolerance, then two gears shall be tested, one above and one below the target speed.

If more than one gear fulfils the target conditions, the gear which is closest to 35 km/h shall be used. If no gear fulfils the target condition for vtest, two gears shall be tested, one above and one below vtest. The target engine speed shall be reached under all conditions.

A stable acceleration condition shall be ensured. If a stable acceleration cannot be ensured in a gear, that gear shall be disregarded.

4.1.2.2.1.2. Vehicles with automatic transmissions, adaptive transmissions and CVTs

The gear selector position for full automatic operation shall be used. The test may then include a gear change to a lower range and a higher acceleration. A gear change to a higher range and a lower acceleration shall not be permitted. A gear shifting to a gear ratio which is not used in urban traffic, at the specified test condition, shall be avoided. Therefore, it shall be permitted to establish and use electronic or mechanical devices to prevent a downshift to a gear ratio which is typically not used at the specified test condition in urban traffic.

If the vehicle includes a transmission design, which provides only a single gear selection (drive), which limits engine speed during the test, the vehicle shall be tested using only a target vehicle speed. If the vehicle uses an engine and transmission combination that does not comply with the requirements set out in point 4.1.2.2.1.1, the vehicle shall be tested using only the target vehicle speed. The target vehicle speed (vBB') for the test is = 35 km/h ± 5km/h. A gear change to a higher range and a lower acceleration is allowed after the reference point of the vehicle passes line PP'. Two tests shall be performed, one with the end speed of vtest = vBB' + 5 km/h, and one with the end speed of vtest = vBB' – 5 km/h. The reported sound level shall be the result of the test with the highest engine speed obtained during the test from AA' to BB'.

4.1.2.2.2. Acceleration test

When the reference point of the vehicle reaches the line AA' the accelerator control shall be fully depressed (without operating the automatic downshift to a lower range than normally used in urban driving) and held fully depressed until the rear of the vehicle passes BB', but the reference point shall be at least 5 m behind BB'. The accelerator control shall then be released.

In the case of articulated vehicles consisting of two non-separable units regarded as a single vehicle, the semi-trailer shall be disregarded in determining when line BB' is crossed.

4.1.3. Interpretation of results

The maximum A-weighted sound pressure level indicated during each passage of the vehicle between the two lines AA' and BB' shall be noted. If a noise peak obviously out of character with the general sound pressure level is observed, the measurement shall be discarded. At least four measurements for each test condition shall be made on each side of the vehicle and for each gear ratio. Left and right side may be measured simultaneously or sequentially. The first four valid consecutive measurement results, within 2 dB(A), allowing for the deletion of non valid results (see point 3.1), shall be used for the calculation of the final result for the given side of the vehicle. The results of each side shall be averaged separately. The intermediate result is the higher value of the two averages mathematically rounded to the first decimal place.

The speed measurements at AA', BB', and PP' shall be noted and used in calculations to the first significant digit after the decimal place.

The calculated acceleration awot test shall be noted to the second digit after the decimal place.

4.1.3.1. Vehicles of categories M1, N1 and M2 ≤ 3 500 kg

The calculated values for the acceleration test and the constant speed test are given by:

Lwot rep = Lwot (i+1) + k * (Lwot(i) – Lwot (i+1))

Lcrs rep = Lcrs(i+1) + k * (Lcrs (i) – Lcrs (i+1))

Where k = (awot ref – awot (i+1))/(awot (i) – awot (i+1))

In the case of a single gear ratio test, the values are the test result of each test.

The final result is calculated by combining Lwot rep and Lcrs rep. The equation is:

Lurban = Lwot rep – kP * (Lwot rep – Lcrs rep)

The weighting factor kP, gives the partial power factor for urban driving. In cases other than a single gear test kP is calculated by:

kP = 1 – (aurban/awot ref)

If only one gear was specified for the test kP is given by:

kP = 1 – (aurban/awot test)

In cases where awot test is less than aurban:

kP = 0

4.1.3.2. Vehicles of categories M2 > 3 500 kg, M3, N2, N3

When one gear is tested, the final result shall be equal to the intermediate result. When two gears are tested the arithmetic mean of the intermediate results shall be calculated.

4.2. Measurement of noise emitted by stationary vehicles

4.2.1. Sound level in the vicinity of vehicles

The measurement results shall be entered into the test report referred to in the Addendum to Appendix 2 to Annex I.

4.2.2. Acoustic measurements

4.2.3. Test site — local conditions as referred to in Figures 2 and 3a to 3d of the Appendix.

4.2.3.1. In the vicinity of the microphone, there shall be no obstacle that could influence the acoustical field and no person shall remain between the microphone and the noise source. The meter observer shall be positioned so as not to influence the meter reading.

4.2.4. Disturbance sound and wind interference

Readings on the measuring instruments produced by ambient noise and wind shall be at least 10 dB(A) below the sound level to be measured. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the sensitivity of the microphone (see point 2.1).

The maximum sound level expressed in A-weighted decibels (dB(A)) shall be measured during the operating period referred to in point 4.2.5.3.2.1.

At least three measurements shall be taken at each measuring point.

4.2.5.2. Positioning and preparation of the vehicle

The vehicle shall be located in the centre part of the test area with the gear selector in the neutral position and the clutch engaged. If the design of the vehicle does not allow this, the vehicle shall be tested in conformity with the manufacturer's prescriptions for stationary engine testing. Before each series of measurements, the engine shall be brought to its normal operating condition, as specified by the manufacturer.

If the vehicle is fitted with a fan or fans having an automatic actuating mechanism, this system shall not be interfered with during the sound level measurements.

The engine hood or compartment cover, if so fitted, shall be closed.

4.2.5.3. Measuring of noise in proximity to the exhaust as referred to in Figure 2 and Figures 3a to 3d of the Appendix.

4.2.5.3.1. Positions of the microphone

4.2.5.3.1.1. The microphone shall be located at a distance of 0,5 m ± 0,01 m from the reference point of the exhaust pipe defined in Figure 2 and Figures 3a to 3d of the Appendix, and at an angle of 45°(± 5°) to the flow axis of the pipe termination. The microphone shall be at the height of the reference point, but not less than 0,2 m from the ground surface. The reference axis of the microphone shall lie in a plane parallel to the ground surface and shall be directed toward the reference point on the exhaust outlet. If two microphone positions are possible, the location farthest laterally from the vehicle longitudinal centreline shall be used. If the flow axis of the exhaust outlet pipe is at 90° to the vehicle longitudinal centreline, the microphone shall be located at the point, which is farthest from the engine.

4.2.5.3.1.2. For vehicles having an exhaust provided with outlets spaced more than 0,3 m apart, measurements shall be made for each outlet. The highest level shall be recorded.

4.2.5.3.1.3. In the case of an exhaust provided with two or more outlets spaced less than 0,3 m apart and which are connected to the same silencer, only one measurement shall be made; the microphone position is related to the outlet nearest to one extreme edge of the vehicle or, when such outlet does not exist, to the outlet which is the highest above the ground.

4.2.5.3.1.4. For vehicles with a vertical exhaust (e.g. commercial vehicles) the microphone shall be placed at the height of the exhaust outlet. Its axis shall be vertical and oriented upwards. It shall be placed at a distance of 0,5 m ± 0,01 m from the exhaust pipe reference point, but never less than 0,2 m from the side of the vehicle nearest to the exhaust.

4.2.5.3.1.5. For exhaust outlets located under the vehicle body, the microphone shall be located a minimum of 0,2 m from the nearest part of the vehicle, at a point closest to, but never less than 0,5 m from the exhaust pipe reference point, and at a height of 0,2 m above the ground, and not in line with the exhaust flow. If it is not physically possible, the angularity requirement in point 4.2.5.3.1.1 need not be met.

4.2.5.3.1.6. Examples of the position of the microphone, depending on the location of the exhaust pipe, are given in Figures 3a-3d of the Appendix.

4.2.5.3.2. Operating conditions of the engine

4.2.5.3.2.1. Target engine speed

—	3 750 min-1 for vehicles with a rated engine speed above 5 000 min-1 and below 7 500 min-1

—	50 % of the engine speed S for vehicles with a rated engine speed ≥ 7 500 min-1.

If the vehicle cannot reach such engine speed, the target engine speed shall be 5 % below the maximum possible engine speed for that stationary test.

4.2.5.3.2.2. Test procedure

The engine speed shall be gradually increased from idle to the target engine speed, not exceeding a tolerance band of ± 3 % of the target engine speed, and held constant. Then the throttle control shall be rapidly released and the engine speed shall return to idle. The sound level shall be measured during a period of operation consisting of maintaining constant engine speed of 1 second and throughout the entire deceleration period. The maximum sound level meter reading during this period of operation, mathematically rounded to the first decimal place, shall be taken as the test value.

4.2.5.3.2.3. Test validation

The measurement shall be regarded as valid if the test engine speed does not deviate from the target engine speed by more than ± 3 % for at least 1 second.

4.2.6. Results

At least three measurements for each test position shall be made. The maximum A-weighted sound pressure level indicated during each of the three measurements shall be recorded. The first three valid consecutive measurement results, within 2 dB(A), allowing for the deletion of non valid results (taking into account the specifications of the test site as referred to in point 3.1), shall be used for the determination of the final result for the given measurement position. The maximum sound level, for all measurement positions, and of the three measurement results, shall constitute the final result.

ANNEX V

COMPRESSED AIR NOISE

1.

METHOD OF MEASUREMENT

The measurement is performed at microphone positions 2 and 6 as shown in Figure 1 of the Appendix, with the vehicle stationary. The highest A-weighted sound level shall be registered during venting the pressure regulator and during ventilating after the use of both the service and parking brakes.

The noise during venting the pressure regulator is measured with the engine at idling speed. The ventilating noise is registered while operating the service and parking brakes; before each measurement, the air-compressor unit has to be brought up to the highest permissible operating pressure, and then the engine switched off.

2.

EVALUATION OF THE RESULTS

For all microphone positions two measurements are taken. In order to compensate for inaccuracies of the measuring equipment, the metre reading is reduced by 1 dB(A), and the reduced value is taken as the result of measurement. The results are taken as valid if the difference between the measurements at one microphone position does not exceed 2 dB(A). The highest value measured is taken as the result. If this value exceeds the sound level limit by 1 dB(A), two additional measurements are to be taken at the corresponding microphone position. In this case, three out of the four results of measurement obtained at this position have to comply with the sound level limit.

3.

LIMITING VALUE

The sound level shall not exceed the limit of 72 dB(A).

Appendix

Figure 1: Microphone positions for measurement of compressed air noise

The measurement is performed at the stationary vehicle in accordance with Figure 1, using two microphone positions at a distance of 7 m from the contour of the vehicles and at 1,2 m above ground.

If the sound level of the vehicle tested does not exceed by more than 1 dB(A) the limit value set out in Annex III, and, where appropriate, point 3 of Annex V, the vehicle type shall be considered to conform to the requirements of this Regulation.

If one of the test results does not comply with the COP requirements of Annex X to Directive 2007/46/EC, two more vehicles of the same type shall be tested pursuant to point 2 of this Annex.

If the test results for the second and the third vehicle comply with the COP requirements of Annex X to Directive 2007/46/EC, the vehicle is considered in compliance with the COP.

If one of the test results of the second or third vehicle does not comply with the COP requirements of Annex X to Directive 2007/46/EC, the vehicle type shall be considered not to conform to the requirements of this Regulation and the manufacturer shall take the necessary measures to re-establish the conformity.

ANNEX VII

MEASURING METHOD TO EVALUATE COMPLIANCE WITH THE ADDITIONAL SOUND EMISSION PROVISIONS

1.

GENERAL

This Annex describes a measuring method to evaluate compliance of the vehicle with the additional sound emission provisions (ASEP) set out in Article 7.

It is not mandatory to perform actual tests when applying for EU type-approval. The manufacturer shall sign the declaration of compliance set out in the Appendix. The approval authority may ask for additional information about the declaration of compliance and carry out the tests described below.

The procedure set out in this Annex requires the performance of a test in accordance with Annex II. The test specified in Annex II shall be carried out on the same test track under conditions similar to those required in the tests prescribed in this Annex.

2.

MEASURING METHOD

2.1 Measuring instruments and condition of measurements

Unless otherwise specified, the measuring instruments, the conditions of the measurements and the condition of the vehicle are equivalent to those specified in points 2 and 3 of Annex II.

If the vehicle has different modes that affect sound emission, all modes shall comply with the requirements of this Annex. In the case where the manufacturer has performed tests to prove to the approval authority compliance with those requirements, the modes used during those tests shall be reported in a test report.

2.2. Method of testing

Unless otherwise specified, the conditions and procedures of points 4.1 to 4.1.2.1.2.2 of Annex II shall be used. For the purpose of this Annex, single test runs shall be measured and evaluated.

2.3. Control range

Operation conditions are as follows:

Vehicle speed VAA ASEP:	vAA ≥ 20 km/h
Vehicle acceleration awot ASEP	awot ≤ 5,0 m/s2
Engine speed nBB ASEP	nBB ≤ 2,0 * PMR–0,222 * s or

nBB ≤ 0,9 * s, whichever is the lowest

Vehicle speed VBB ASEP:

if nBB ASEP is reached in one gear	vBB ≤ 70 km/h
in all other cases	vBB ≤ 80 km/h
gears	K ≤ gear ratio i as determined in Annex II

If the vehicle, in the lowest valid gear, does not achieve the maximum engine speed below 70 km/h, the vehicle speed limit is 80 km/h.

2.4. Gear ratios

The ASEP requirements apply to every gear ratio K that leads to test results within the control range as defined in point 2.3 of this Annex.

In case of vehicles with automatic transmissions, adaptive transmissions and CVTs tested with non-locked gear ratios, the test may include a gear ratio change to a lower range and a higher acceleration. A gear change to a higher range and a lower acceleration is not allowed. A gear shift which leads to a condition that is not in compliance with the boundary conditions shall be avoided. In such a case, it is permitted to establish and use electronic or mechanical devices, including alternate gear selector positions. In order for the ASEP test to be representative and repeatable (to the approval authority), the vehicles shall be tested using production gearbox calibration.

2.5. Target conditions

The sound emission shall be measured in each valid gear ratio at the four test points as specified below.

The first test point P1 is defined by using an entry speed vAA of 20 km/h. If a stable acceleration condition cannot be achieved, the speed shall be increased in steps of 5 km/h until a stable acceleration is reached.

The fourth test point P4 is defined by the maximum vehicle speed at BB' in that gear ratio within the boundary conditions in accordance with point 2.3.

The other two test points are calculated using the following formula:

Test Point Pj: vBB_j = vBB_1 + ((j – 1)/3) * (vBB_4 – vBB_1) for j = 2 and 3

Where:

vBB_1	=	vehicle speed at BB' of test point P1
vBB_4	=	vehicle speed at BB' of test point P4

Tolerance for vBB_j: ±3 km/h

For all test points the boundary conditions as specified in point 2.3 shall be met.

2.6. Test of the vehicle

The path of the centreline of the vehicle shall follow line CC' as closely as possible throughout the entire test, starting from the approach to line AA' until the rear of the vehicle passes line BB'.

At line AA' the accelerator shall be fully depressed. To achieve a more stable acceleration or to avoid a down shift between line AA' and BB' pre-acceleration before line AA' may be used. The accelerator shall be kept in depressed condition until the rear of the vehicle reaches line BB'.

For every separate test run, the following parameters shall be determined and noted:

The maximum A-weighted sound pressure level of both sides of the vehicle, indicated during each passage of the vehicle between the two lines AA' and BB', shall be mathematically rounded to the first decimal place (Lwot,kj). If a sound peak obviously out of character with the general sound pressure level is observed, the measurement shall be discarded. Left and right side may be measured simultaneously or separately.

The vehicle speed readings at AA' and BB' shall be reported with the first significant digit after the decimal place (vAA,kj; vBB,kj).

If applicable, the engine speed readings at AA' and BB' shall be reported as a full integer value (nAA,kj; nBB,kj).

The calculated acceleration shall be determined in accordance to the formula in point 4.1.2.1.2 of Annex II and reported to the second digit after the decimal place (awot,test,kj).

3.

ANALYSIS OF RESULTS

3.1. Determination of the anchor point for each gear ratio

For measurements in gear i and lower, the anchor point consists of the maximum sound level Lwoti, the reported engine speed nwoti and vehicle speed vwoti at BB' of gear ratio i of the acceleration test in Annex II.

Lanchor,i	=	Lwoti,Annex II
nanchor,i	=	nBB,woti,Annex II
vanchor,i	=	vBB,woti,Annex II

For measurements in gear i+1 the anchor point consists of the maximum sound level Lwoti+1, the reported engine speed nwoti+1 and vehicle speed vwoti+1 at BB' of gear ratio i+1 of the acceleration test in Annex II.

Lanchor,i+1	=	Lwoti+1,Annex II
nanchor,i+1	=	nBB,woti+1,Annex II
vanchor,i+1	=	vBB,woti+1,Annex II

3.2. Slope of the regression line for each gear

The sound measurements shall be evaluated as a function of engine speed in accordance with point 3.2.1.

3.2.1. Calculation of the slope of the regression line for each gear

The linear regression line is calculated using the anchor point and the four correlated additional measurements.

Formula (in dB/1 000 min-1)

With Formula and Formula

where nj = engine speed measured at line BB'

3.2.2. Slope of the regression line for each gear

The Slopek of a particular gear for the further calculation is the derived result of the calculation in point 3.2.1 rounded to the first decimal place, but not higher than 5 dB/1 000 min–1.

3.3. Calculation of the linear sound level increase expected for each measurement

The sound level LASEP,kj for measurement point j and gear k shall be calculated using the engine speeds measured for each measurement point, using the slope specified in point 3.2 to the specific anchor point for each gear ratio.

For nBB_k,j ≤ nanchor,k:

LASEP_k,j = Lanchor_k + (Slopek – Y) * (nBB_k,j – nanchor,k)/1 000

For nBB_k,j > nanchor,k:

LASEP_k,j = Lanchor_k + (Slopek + Y) * (nBB_k,j – nanchor,k)/1 000

Where Y = 1

3.4. Samples

On request of the approval authority two additional runs within the boundary conditions in accordance with point 2.3 shall be carried out.

4.

INTERPRETATION OF RESULTS

Every individual noise measurement shall be evaluated.

The sound level of every specified measurement point shall not exceed the limits given below:

Lkj ≤ LASEP_k.j + x

With:

x	=	3 dB(A) for vehicle with a non-lockable automatic transmission or non-lockable CVT
x	=	2 dB(A) + limit value – Lurban of Annex II for all other vehicles

If the measured sound level at a point exceeds the limit, two additional measurements at the same point shall be carried out to verify the measurement uncertainty. The vehicle is still in compliance with ASEP, if the average of the three valid measurements at this specific point fulfils the specification.

5.

REFERENCE SOUND ASSESSMENT

The reference sound is assessed at a single point in one discrete gear, simulating an acceleration condition starting with an entry speed at vaa equal to 50 km/h and assuming an exit speed at vbb equal to 61 km/h. The sound compliance at this point can either be calculated using the results of point 3.2.2 and the specification below or be evaluated by direct measurement using the gear as specified below.

5.1 The determination of gear K is as follows:

K	=	3 for all manual transmission and for automatic transmission with up to 5 gears;
K	=	4 for automatic transmission with 6 or more gears

If no discrete gears are available, e.g. for non-lockable automatic transmissions or non-lockable CVTs, the gear ratio for further calculation shall be determined from the acceleration test result in Annex II using the reported engine speed and vehicle speed at line BB'.

5.2. Determination of reference engine speed nref_K

The reference engine speed, nref_K, shall be calculated using the gear ratio of gear K at the reference speed of vref = 61 km/h.

5.3. Calculation of Lref

Lref = Lanchor_K + SlopeK * (nref_K – nanchor_K)/1 000

Lref shall be less than or equal to 76 dB(A).

For vehicles fitted with a manual gear box having more than four forward gears and equipped with an engine developing a rated maximum net power greater than 140 kW and having a rated maximum net power/maximum-mass ratio greater than 75 kW/t, Lref shall be less than or equal to 79 dB(A).

For vehicles fitted with an automatic gear box having more than four forward gears and equipped with an engine developing a rated maximum net power greater than 140 kW and having a rated maximum net power/maximum-mass ratio greater than 75 kW/t, Lref shall be less than or equal to 78 dB(A).

6.

EVALUATION OF ASEP USING THE PRINCIPLE OF L urban

6.1 General

This evaluation procedure is an alternative selected by the manufacturer to the procedure described in point 3 of this Annex and is applicable to all vehicle technologies. The manufacturer shall be responsible for determining the correct manner of testing. Unless otherwise specified, all testing and calculation shall be as specified in Annex II.

6.2. Calculation of Lurban ASEP

From any Lwot ASEP as measured in accordance with this Annex, Lurban ASEP shall be calculated as follows:

(a)	calculate awot test ASEP as specified in point 4.1.2.1.2.1 or point 4.1.2.1.2.2 of Annex II, as applicable;

(b)	determine the vehicle speed (VBB ASEP) at BB' during the Lwot ASEP test;

(c)	calculate kP ASEP as follows: kP ASEP = 1 – (aurban/awot test ASEP) Test results where awot test ASEP are less than aurban shall be disregarded.

(d)	calculate Lurban measured ASEP as follows: Lurban measured ASEP = Lwot ASEP – kP ASEP * (Lwot ASEP – Lcrs) For further calculation, use the Lurban from Annex II without rounding, including the digit after the decimal (xx.x).

(e)	calculate Lurban normalized as follows: Lurban normalized = Lurban measured ASEP – Lurban

(f)	calculate Lurban ASEP as follows: Lurban ASEP = Lurban normalized – (0,15 * (VBB ASEP – 50))

(g)	compliance with sound level limits: Lurban ASEP shall be less than or equal to 3,0 dB.

SPECIFICATIONS

5.1. General specifications

5.1.1. The replacement silencing system, or components thereof, shall be designed, constructed and capable of being mounted so as to ensure that the vehicle complies with this Regulation under normal conditions of use, notwithstanding any vibrations to which it may be subject.

5.1.2. The silencing system, or components thereof, shall be designed, constructed and capable of being mounted so that reasonable resistance to the corrosion phenomenon to which it is exposed is obtained having regard to the conditions of use of the vehicle.

5.1.3. Additional prescriptions related to tamperability and manually adjustable multi-mode exhaust or silencing systems

5.1.3.1. All exhaust or silencing systems shall be constructed in a way that does not easily permit removal of baffles, exit-cones and other parts whose primary function is as part of the silencing/expansion chambers. Where incorporation of such a part is unavoidable, its method of attachment shall be such that removal is not facilitated easily (e.g. with conventional threaded fixings) and shall also be attached such that removal causes permanent/irrecoverable damage to the assembly.

5.1.3.2. Exhaust or silencing systems with multiple, manually adjustable operating modes shall meet all requirements in all operating modes. The reported sound levels shall be those resulting from the mode with the highest sound levels.

5.2. Specifications regarding sound levels

5.2.1. Conditions of measurement

5.2.1.1. The noise test of the silencing system and the replacement silencing system has to be executed with the same normal tyres, as defined in paragraph 2 of UNECE Regulation No 117. At the request of the manufacturer, the tests shall not be done with traction tyres, special use tyres or snow tyres, as defined in paragraph 2 of UNECE Regulation No 117. Such tyres could increase the sound level of the vehicle or would have a masking effect on the noise reduction performance comparison. The tyres may be of used condition but shall satisfy legal requirements for in-traffic use.

5.2.2. The noise reduction performance of the replacement silencing system, or components thereof, shall be verified by means of the methods described in point 1 of Annex II. In particular, for the application of this point, reference shall be made to the amendment level of this Regulation which was in force at the time of type-approval of the new vehicle.

(a)

Measurement with running vehicle

When the replacement silencing system, or components thereof, is mounted on the vehicle described in point 1.3.3, the sound levels obtained shall satisfy one of the following conditions:

(i)	the value measured (rounded to the nearest integer) shall not exceed by more than 1 dB(A) the type-approval value obtained under this Regulation with the type of vehicle concerned;

(ii)

the value measured (before any rounding to the nearest integer) shall not exceed by more than 1 dB(A) the noise value measured (before any rounding to the nearest integer) on the vehicle described in point 1.3.3., when this is fitted with a silencing system corresponding to the type fitted to the vehicle when submitted for type-approval under this Regulation.

Where back-to-back comparison of the replacement silencing system with the original system is chosen, for the application of point 4.1.2.1.4.2 and/or point 4.1.2.2.1.2 of Annex II, it is allowed to have a gear change to higher accelerations and the use of electronic or mechanical devices to prevent this downshift is not mandatory. If under these conditions the sound level of the test vehicle becomes higher than the COP values, the technical service will decide on the representativeness of the test vehicle.

(b)

Measurement with stationary vehicle

When the replacement silencing system, or components thereof, is mounted on the vehicle described in point 1.3.3, the sound levels obtained shall satisfy one of the following conditions:

(i)	the value measured (rounded to the nearest integer) shall not exceed by more than 2 dB(A) the type-approval value obtained under this Regulation with the type of vehicle concerned;

(ii)

the value measured (before any rounding to the nearest integer) shall not exceed by more than 2 dB(A) the noise value measured (before any rounding to the nearest integer) on the vehicle described in point 1.3.3, when this is fitted with a silencing system corresponding to the type fitted to the vehicle when submitted for type-approval under this Regulation.

5.2.3. Further to the requirements of Annex II, any replacement silencing system, or components thereof, has to fulfil the applicable specifications of Annex VII. For replacement silencing systems intended for vehicles type approved in accordance with Directive 70/157/EEC the requirements of Annex VII as well as the specifications of points 5.2.3.1 to 5.2.3.3 of this Annex do not apply.

5.2.3.1. Where the replacement silencing system, or components thereof, is a system or components with variable geometry, in the application for type-approval the manufacturer shall provide a statement in conformity with the Appendix to Annex VII that the silencing system type to be approved complies with the requirements of point 5.2.3 of this Annex. The approval authority may require any relevant test to verify the compliance of the silencing system type to the additional sound emission provisions.

5.2.3.2. Where the replacement silencing system, or components thereof, is not a system with variable geometry, it is sufficient in the application for type-approval that the manufacturer provides a statement in conformity with the Appendix to Annex VII that the silencing system type to be approved complies with the requirements of point 5.2.3 of this Annex.

5.2.3.3. The compliance statement shall read as follows: ‘(Name of the manufacturer) attests that the silencing system of this type complies with the requirements of point 5.2.3 of Annex IX to Regulation (EU) No 540/2014. (Name of the manufacturer) makes this statement in good faith, after having performed an appropriate engineering evaluation of the sound emission performance over the applicable range of operating conditions.’

5.3. Measurement of the vehicle performances

5.3.1. The replacement silencing system, or components thereof, shall be such as to ensure that vehicle performance is comparable with that achieved with the original equipment silencing system or components thereof.

5.3.2. The replacement silencing system or, depending on the manufacturer's choice, the components of that system shall be compared with an original silencing system, or components thereof, which are also in new condition, successively mounted on the vehicle mentioned in point 1.3.3.
