2.9.1.   
  ‘Illuminating surface of a lighting device’ (paragraphs 2.7.9, 2.7.10, 2.7.19, 2.7.21 and 2.7.26) means the orthogonal projection of the full aperture of the reflector, or in the case of headlamps with an ellipsoidal reflector of the ‘projection lens’, on a transverse plane. If the lighting device has no reflector, the definition of paragraph 2.9.2 shall be applied. If the light emitting surface of the lamp extends over part only of the full aperture of the reflector, then the projection of that part only is taken into account.

In the case of a dipped-beam headlamp, the illuminating surface is limited by the apparent trace of the cut-off on to the lens. If the reflector and lens are adjustable relative to one another, the mean adjustment should be used;

2.9.2.   
  ‘Illuminating surface of a light-signalling device other than a retro-reflector’ (paragraphs 2.7.11 to 2.7.15, 2.7.18, 2.7.20 and 2.7.22 to 2.7.25) means the orthogonal projection of the lamp in a plane perpendicular to its axis of reference and in contact with the exterior light-emitting surface of the lamp, this projection being bounded by the edges of screens situated in this plane, each allowing only 98 % of the total luminous intensity of the light to persist in the direction of the axis of reference.

To determine the lower, upper and lateral limits of the illuminating surface only screens with horizontal or vertical edges shall be used to verify the distance to the extreme edges of the vehicle and the height above the ground.

For other applications of the illuminating surface, e.g. distance between two lamps or functions, the shape of the periphery of this illuminating surface shall be used. The screens shall remain parallel, but other orientations are allowed to be used.

In the case of a light-signalling device whose illuminating surface encloses either totally or partially the illuminating surface of another function or encloses a non-lighted surface, the illuminating surface may be considered to be the light emitting surface itself.

2.9.3.   
  ‘Illuminating surface of a retro-reflector’ (paragraph 2.7.16) means, as declared by the applicant during the component approval procedure for the retro-reflectors, the orthogonal projection of a retro-reflector in a plane perpendicular to its axis of reference and delimited by planes contiguous to the declared outermost parts of the retro-reflectors’ optical system and parallel to that axis. For the purposes of determining the lower, upper and lateral edges of the device, only horizontal and vertical planes shall be considered.

2.10.   The ‘apparent surface’ for a defined direction of observation means, at the request of the manufacturer or his duly accredited representative, the orthogonal projection of:

| | either the boundary of the illuminating surface projected on the exterior surface of the lens (a-b); |
| --- | --- |

either the boundary of the illuminating surface projected on the exterior surface of the lens (a-b);

| | or the light-emitting surface (c-d); |
| --- | --- |

| --- | --- |

in a plane perpendicular to the direction of observation and tangential to the most exterior point of the lens (see Annex 3 to this Regulation).

2.11.   
  ‘Axis of reference’ (or ‘reference axis’) means the characteristic axis of the lamp determined by the manufacturer (of the lamp) for use as the direction of reference (H = 0°, V = 0°) for angles of field for photometric measurements and for installing the lamp on the vehicle;

2.12.   
  ‘Centre of reference’ means the intersection of the axis of reference with the exterior light-emitting surface; it is specified by the manufacturer of the lamp;

2.13.   
  ‘Angles of geometric visibility’ means the angles which determine the field of the minimum solid angle in which the apparent surface of the lamp must be visible. That field of the solid angle is determined by the segments of the sphere of which the centre coincides with the centre of reference of the lamp and the equator is parallel with the ground. These segments are determined in relation to the axis of reference. The horizontal angles ß correspond to the longitude and the vertical angles α to the latitude. There must be no obstacle on the inside of the angles of geometric visibility to the propagation of light from any part of the apparent surface of the lamp observed from infinity.

If measurements are taken closer to the lamp, the direction of observation must be shifted parallel to achieve the same accuracy.

On the inside of the angles of geometric visibility no account is taken of obstacles, if they were already presented when the lamp was type-approved.

If, when the lamp is installed, any part of the apparent surface of the lamp is hidden by any further parts of the vehicle, proof shall be furnished that the part of the lamp not hidden by obstacles still conforms to the photometric values prescribed for the approval of the device as an optical unit (see Annex 3 of this Regulation). Nevertheless, when the vertical angle of geometric visibility below the horizontal may be reduced to 5° (lamp at less than 750 mm above the ground) the photometric field of measurements of the installed optical unit may be reduced to 5° below the horizontal.

2.14.   
  ‘Extreme outer edge’ on either side of the vehicle, means the plane parallel to the median longitudinal plane of the vehicle and touching its lateral outer edge, disregarding the projection:

5.   GENERAL SPECIFICATIONS

5.1.   The lighting and light-signalling devices shall be so fitted that under normal conditions of use as defined in paragraphs 2.24, 2.24.1 and 2.24.2 and notwithstanding any vibrations to which they may be subjected, they retain the characteristics prescribed by this Regulation and enable the vehicle to comply with the requirements of this Regulation. In particular, it shall not be possible for the lamps to be inadvertently maladjusted.

5.2.   The illuminating lamps described in paragraphs 2.7.9, 2.7.10 and 2.7.19 shall be so installed that correct adjustment of their orientation can easily be carried out.

5.3.   For all light-signalling devices, including those mounted on the side panels, the reference axis of the lamp when fitted to the vehicle must be parallel to the bearing plane of the vehicle on the road; in addition it must be perpendicular to the median longitudinal plane of the vehicle in the case of side retro-reflectors and of side-marker lamps and parallel to that plane in the case of all other signalling devices. In each direction a tolerance of ± 3° shall be allowed. In addition, any specific instructions as regards fitting laid down by the manufacturer must be complied with.

5.4.   In the absence of specific instructions, the height and orientation of the lamps shall be verified with the vehicle unladen and placed on a flat, horizontal surface in the condition defined in paragraphs 2.24, 2.24.1 and 2.24.2.

5.5.   In the absence of specific instructions lamps constituting a pair shall:

| 5.5.1. | be fitted to the vehicle symmetrically in relation to the median longitudinal plane (this estimate to be based on the exterior geometrical form of the lamp and not on the edge of its illuminating surface referred to in paragraph 2.9); |
| --- | --- |

5.5.1.

be fitted to the vehicle symmetrically in relation to the median longitudinal plane (this estimate to be based on the exterior geometrical form of the lamp and not on the edge of its illuminating surface referred to in paragraph 2.9);

| 5.5.2. | be symmetrical to one another in relation to the median longitudinal plane, this requirement is not valid with regard to the interior structure of the lamp; |
| --- | --- |

5.5.2.

be symmetrical to one another in relation to the median longitudinal plane, this requirement is not valid with regard to the interior structure of the lamp;

| 5.5.3. | satisfy the same colorimetric requirements; and |
| --- | --- |

5.5.3.

satisfy the same colorimetric requirements; and

| 5.5.4. | have substantially identical photometric characteristics. |
| --- | --- |

5.5.4.

have substantially identical photometric characteristics.

5.6.   On vehicles whose external shape is asymmetrical the above requirements shall be satisfied so far as is possible.

5.7.   Grouped, combined or reciprocally incorporated lamps

Grouped, combined or reciprocally incorporated lamps

5.7.1.   Lamps may be grouped, combined or reciprocally incorporated with one another provided that all requirements regarding colour, position, orientation, geometric visibility, electrical connections and other requirements, if any, are fulfilled.

5.7.1.1.   However, where stop lamps and direction indicator lamps are grouped, any horizontal or vertical straight line passing through the projections of the apparent surfaces of these functions on a plane perpendicular to the reference axis, shall not intersect more than two borderlines separating adjacent areas of different colour.

5.7.2.   Where the apparent surface of a single lamp is composed of two or more distinct parts, it shall satisfy the following requirements:

5.7.2.1.   Either the total area of the projection of the distinct parts on a plane tangent to the exterior surface of the transparent material and perpendicular to the reference axis shall occupy not less than 60 % of the smallest quadrilateral circumscribing the said projection, or the distance between two adjacent/tangential distinct parts shall not exceed 15 mm when measured perpendicularly to the reference axis.

5.8.   The maximum height above the ground shall be measured from the highest point and the minimum height from the lowest point of the apparent surface in the direction of the reference axis.

In the case of dipped-beam headlamp, the minimum height in relation to the ground is measured from the lowest point of the effective outlet of the optical system (e.g. reflector, lens, projection lens) independent of its utilisation.

Where the (maximum and minimum) height above the ground clearly meets the requirements of the Regulation, the exact edges of any surface need not be determined.

5.8.1.   The position, as regards width, will be determined from that edge of the apparent surface in the direction of the reference axis which is the furthest from the median longitudinal plane of the vehicle when referred to the overall width, and from the inner edges of the apparent surface in the direction of the reference axis when referred to the distance between lamps.

Where the position, as regards width, clearly meets the requirements of the Regulation, the exact edges of any surface need not be determined.

5.9.   In the absence of specific instructions, no lamps other than direction-indicator lamps, the vehicle-hazard warning signal and amber side-marker lamps complying with paragraph 6.18.7 below, shall be flashing lamps.

5.10.   No red light which could give rise to confusion shall be emitted from a lamp as defined in paragraph 2.7 in a forward direction and no white light which could give rise to confusion, other than from the reversing lamp, shall be emitted from a lamp as defined in paragraph 2.7 in a rearward direction. No account shall be taken of lighting devices fitted for the interior lighting of the vehicle. In case of doubt, this requirement shall be verified as follows:

| 5.10.1. | For the visibility of red light towards the front of a vehicle, with the exception of a red rearmost side-marker lamp, there must be no direct visibility of the apparent surface of a red lamp if viewed by an observer moving within Zone 1 as specified in Annex 4. |
| --- | --- |

5.10.1.

For the visibility of red light towards the front of a vehicle, with the exception of a red rearmost side-marker lamp, there must be no direct visibility of the apparent surface of a red lamp if viewed by an observer moving within Zone 1 as specified in Annex 4.

| 5.10.2. | For the visibility of white light towards the rear, there must be no direct visibility of the apparent surface of a white lamp if viewed by an observer moving within Zone 2 in a transverse plane situated 25 m behind the vehicle (see Annex 4); |
| --- | --- |

5.10.2.

For the visibility of white light towards the rear, there must be no direct visibility of the apparent surface of a white lamp if viewed by an observer moving within Zone 2 in a transverse plane situated 25 m behind the vehicle (see Annex 4);

| 5.10.3. | In their respective planes, the zones 1 and 2 explored by the eye of the observer are bounded:






  5.10.3.1. | in height, by two horizontal planes 1 m and 2,2 m respectively above the ground; |
| --- | --- | --- |

5.10.3.

In their respective planes, the zones 1 and 2 explored by the eye of the observer are bounded:

5.10.3.1.

in height, by two horizontal planes 1 m and 2,2 m respectively above the ground;

| 5.10.3.2. | in width, by two vertical planes which, forming to the front and to the rear respectively an angle of 15° outwards from the vehicle's median longitudinal plane, pass through the point or points of contact of vertical planes parallel to the vehicle's median longitudinal plane delimiting the vehicle's overall width; if there are several points of contact, the foremost shall correspond to the forward plane and the rearmost to the rearward plane. |
| --- | --- |

5.10.3.2.

in width, by two vertical planes which, forming to the front and to the rear respectively an angle of 15° outwards from the vehicle's median longitudinal plane, pass through the point or points of contact of vertical planes parallel to the vehicle's median longitudinal plane delimiting the vehicle's overall width; if there are several points of contact, the foremost shall correspond to the forward plane and the rearmost to the rearward plane.

5.11.   The electrical connections must be such that the front and rear position lamps, the end-outline marker lamps, if they exist, the side-marker lamps, if they exist, and the rear registration plate lamp can only be switched on and off simultaneously. This condition does not apply when using front and rear position lamps, as well as side-marker lamps when combined or reciprocally incorporated with said lamps, as parking lamps and when side-marker lamps are permitted to flash.

5.12.   The electrical connections must be such that the main-beam and dipped-beam headlamps and the front fog lamps cannot be switched on unless the lamps referred to in paragraph 5.11 are also switched on. This requirement shall not apply, however, to main-beam or dipped-beam headlamps when their luminous warnings consist of the intermittent lighting up at short intervals of the main-beam headlamp or the intermittent lighting up at short intervals of the dipped-beam headlamp or the alternate lighting up at short intervals of the main-beam and dipped beam headlamps.

5.13.   Tell-tale

Where a closed-circuit tell-tale is prescribed by this Regulation it may be replaced by an ‘operating’ tell-tale.

5.14.   Concealable lamps

5.14.1.   The concealment of lamps shall be prohibited, with the exception of the main-beam headlamps, the dipped-beam headlamps and the front fog lamps, which may be concealed when they are not in use.

5.14.2.   In the event of any failure affecting the operation of the concealment device(s) the lamps shall remain in the position of use, if already in use, or shall be capable of being moved into the position of use without the aid of tools.

5.14.3.   It must be possible to move the lamps into the position of use and to switch them on by means of a single control, without excluding the possibility of moving them into the position of use without switching them on. However, in the case of grouped main-beam and dipped-beam headlamps, the control referred to above is required only to activate the dipped-beam headlamps.

5.14.4.   It must not be possible deliberately, from the driver's seat, to stop the movement of switched-on lamps before they reach the position of use. If there is a danger of dazzling other road users by the movement of the lamps, they may light up only when they have reached their position of use.

5.14.5.   When the concealment device has a temperature of – 30 °C to + 50 °C the headlamps must be capable of reaching the position of use within three seconds of initial operation of the control.

5.16.   Number of lamps

5.16.1.   The number of lamps mounted on the vehicle should be equal to the number(s) specified in each of paragraphs 6.1 to 6.20.

5.17.   Any lamp may be installed on movable components provided that the conditions specified in paragraphs 5.18, 5.19 and 5.20 are fulfilled.

5.18.   Rear position lamps, rear direction-indicators and rear retro-reflectors, triangular as well as non triangular, may be installed on movable components only:

| 5.18.1. | if at all fixed positions of the movable components the lamps on the movable components meet all the position, geometric visibility and photometric requirements for those lamps. Should the above functions be obtained by an assembly of two lamps marked ‘D’ (see paragraph 2.16.1) only one of these lamps needs to meet the above-mentioned requirements;
  or |
| --- | --- |

5.18.1.

if at all fixed positions of the movable components the lamps on the movable components meet all the position, geometric visibility and photometric requirements for those lamps. Should the above functions be obtained by an assembly of two lamps marked ‘D’ (see paragraph 2.16.1) only one of these lamps needs to meet the above-mentioned requirements;

or

| 5.18.2. | where additional lamps for the above functions are fitted and are activated, when the movable component is in any fixed open position, provided that these additional lamps satisfy all the position, geometric visibility and photometric requirements applicable to the lamps installed on the movable component. |
| --- | --- |

5.18.2.

where additional lamps for the above functions are fitted and are activated, when the movable component is in any fixed open position, provided that these additional lamps satisfy all the position, geometric visibility and photometric requirements applicable to the lamps installed on the movable component.

5.19.   When the movable components are in a position other than a ‘normal position of use’, the devices installed on them shall not cause undue discomfort to road users.

5.20.   When a lamp is installed on a movable component and the movable component is in the ‘normal position(s) of use’, the lamp must always return to the position(s) specified by the manufacturer in accordance with this Regulation. In the case of dipped-beam headlamps and front fog lamps, this requirement shall be considered satisfied if, when the movable components are moved and returned to the normal position 10 times, no value of the angular inclination of these lamps, relative to its support, measured after each operation of the movable component, differs by more than 0,15 % from the average of the 10 measured values. If this value is exceeded each limit specified in paragraph 6.2.6.1.1 shall then be modified by this excess to decrease the allowed range of inclinations when checking the vehicle according to Annex 6.

5.21.   The apparent surface in the direction of the reference axis of front and rear position lamps, front and rear direction-indicator lamps and retro-reflectors shall not be hidden more than 50 % by any movable component, with or without a light-signalling device installed on it, in any fixed position different from the ‘normal position of use’.

If the above requirement is not practicable:

| 5.21.1. | additional lamps satisfying all the position, geometric visibility and photometric requirements for the above indicated lamps shall be activated when the apparent surface in the direction of the reference axis of these lamps is more than 50 % hidden by the movable component;
  or |
| --- | --- |

5.21.1.

additional lamps satisfying all the position, geometric visibility and photometric requirements for the above indicated lamps shall be activated when the apparent surface in the direction of the reference axis of these lamps is more than 50 % hidden by the movable component;

or

| 5.21.2. | a remark in the communication form (item 10.1 of Annex 1) shall inform other Administrations that more than 50 % of the apparent surface in the direction of the reference axis can be hidden by the movable components;
  and
  a notice in the vehicle shall inform the user that in certain position(s) of the movable components other road users shall be warned of the presence of the vehicle on the road; for example by means of a warning triangle or other devices according to national requirements for use on the road. |
| --- | --- |

5.21.2.

a remark in the communication form (item 10.1 of Annex 1) shall inform other Administrations that more than 50 % of the apparent surface in the direction of the reference axis can be hidden by the movable components;

and

a notice in the vehicle shall inform the user that in certain position(s) of the movable components other road users shall be warned of the presence of the vehicle on the road; for example by means of a warning triangle or other devices according to national requirements for use on the road.

| --- | --- |

5.21.3.

Paragraph 5.21.2 does not apply to retro-reflectors.

5.22.   With the exception of retro-reflectors, a lamp even bearing an approval mark is deemed not to be present when it cannot be made to operate by the sole installation of a light source.

5.23.   Lamps shall be fitted in a vehicle in such a way that the light source can be correctly replaced according to the instructions of the vehicle manufacturer without the use of special tools, other than those provided with the vehicle by the manufacturer. This requirement is not applicable to:

| (a) | devices approved with a non-replaceable light source; |
| --- | --- |

(a)

devices approved with a non-replaceable light source;

| (b) | devices approved with light sources according to Regulation No 99. |
| --- | --- |

(b)

devices approved with light sources according to Regulation No 99.

5.24.   Any temporary fail-safe replacement of the light-signalling function of a rear position lamp is allowed, provided that the substituting function in case of a failure is similar in colour, main intensity and position to the function that has ceased to operate and provided that the substituting device remains operational in its original safety function. During substitution, a tell-tale on the dashboard (see paragraph 2.18 of this Regulation) shall indicate occurrence of a temporary replacement and need for repair.

6.   INDIVIDUAL SPECIFICATIONS

6.1.   Main-beam headlamp

6.1.1.   Presence

Mandatory on motor vehicles. Prohibited on trailers.

6.1.2.   Number

Two or four.

For vehicles of the category N3:

3

Two extra main-beam headlamps may be installed.

Where a vehicle is fitted with four concealable headlamps the installation of two additional headlamps shall only be authorised for the purpose of light-signalling, consisting of intermittent illumination, at short intervals (see paragraph 5.12) in daylight.

6.1.3.   Arrangement

No individual specifications.

6.1.4.   Position

6.1.4.1.   In width: no individual specifications.

6.1.4.2.   In height: no individual specifications.

6.1.4.3.   In length: at the front of the vehicle and fitted in such a way that the light emitted does not cause discomfort to the driver either directly or indirectly through the rear-view mirrors and/or other reflecting surfaces of the vehicle.

6.1.5.   Geometric visibility

The visibility of the illuminating surface, including its visibility in areas which do not appear to be illuminated in the direction of observation considered, must be ensured within a divergent space defined by generating lines based on the perimeter of the illuminating surface and forming an angle of not less than 5° with the axis of reference of the headlamp. The origin of the angles of geometric visibility is the perimeter of the projection of the illuminating surface on a transverse plane tangent to the foremost part of the lens of the headlamp.

6.1.6.   Orientation

Towards the front.

Not more than one main-beam headlamp on each side of the vehicle may swivel to produce bend lighting.

6.1.7.   Electrical connections

6.1.7.1.   The main-beam headlamps may be switched on either simultaneously or in pairs. In case the extra two main-beam headlamps are installed, as permitted under paragraph 6.1.2 for vehicles of the category N3 only, no more than two pairs may be simultaneously lit. For changing over from the dipped to the main beam at least one pair of main-beam headlamps shall be switched on. For changing over from the main-beam to the dipped-beam all main-beam headlamps shall be switched off simultaneously.

3

6.1.7.2.   The dipped-beams may remain switched on at the same time as the main beams.

6.1.7.3.   Where four concealable headlamps are fitted their raised position must prevent the simultaneous operation of any additional headlamps fitted, if these are intended to provide light signals consisting of intermittent illumination at short intervals (see paragraph 5.12) in daylight.

6.1.8.   Tell-tale

Circuit-closed tell-tale mandatory.

6.1.9.   Other requirements

6.1.9.1.   The aggregate maximum intensity of the main-beam headlamps which can be switched on simultaneously shall not exceed 225 000 cd, which corresponds to a reference value of 75.

6.1.9.2.   This maximum intensity shall be obtained by adding together the individual reference marks which are indicated on the several headlamps. The reference mark ‘10’ shall be given to each of the headlamps marked ‘R’ or ‘CR’.

6.2.   Dipped-beam headlamp

6.2.1.   Presence

Mandatory on motor vehicles. Prohibited on trailers.

6.2.2.   Number

Two.

6.2.3.   Arrangement

No special requirement.

6.2.4.   Position

6.2.4.1.   In width: that edge of the apparent surface in the direction of the reference axis which is farthest from the vehicle's median longitudinal plane shall be not more than 400 mm from the extreme outer edge of the vehicle.

The inner edges of the apparent surfaces in the direction of the reference axes shall be not less than 600 mm apart. This does not apply, however, for M1 and N1 category vehicles; for all other categories of motor vehicles this distance may be reduced to 400 mm where the overall width of the vehicle is less than 1 300 mm.

1

1

6.2.4.2.   In height: not less than 500 mm and not more than 1 200 mm above the ground. For category N3G (off-road) vehicles (7) the maximum height may be increased to 1 500 mm.

3

7

6.2.4.3.   In length: at the front of the vehicle. This requirement shall be deemed to be satisfied if the light emitted does not cause discomfort to the driver either directly, or indirectly through the rear-view mirrors and/or other reflecting surfaces of the vehicle.

6.2.5.   Geometric visibility

Defined by angles α and ß as specified in paragraph 2.13:

| α | = | 15° upwards and 10° downwards, |
| --- | --- | --- |
| ß | = | 45° outwards and 10° inwards. |

α

=

15° upwards and 10° downwards,

ß

=

45° outwards and 10° inwards.

Since the photometric values required for dipped-beam headlamps do not cover the full geometric field of vision, a minimum value of 1 cd in the space remaining is required for type-approval purposes. The presence of partitions or other items of equipment near the headlamp shall not give rise to secondary effects causing discomfort to other road users.

6.2.6.   Orientation

Towards the front.

6.2.6.1.   Vertical orientation

6.2.6.1.1.   The initial downward inclination of the cut-off of the dipped-beam to be set in the unladen vehicle state with one person in the driver's seat shall be specified within an accuracy of 0.1 % by the manufacturer and indicated in a clearly legible and indelible manner on each vehicle close to either headlamp or the manufacturer's plate by the symbol shown in Annex 7.

The value of this indicated downward inclination shall be defined in accordance with paragraph 6.2.6.1.2.

6.2.6.1.2.

6.2.6.2.2.   However, devices which are adjusted manually, either continuously or non-continuously, shall be permitted, provided they have a stop position at which the lamps can be returned to the initial inclination defined in paragraph 6.2.6.1.1 by means of the usual adjusting screws or similar means.

These manually adjustable devices must be operable from the driver's seat.

Continually adjustable devices must have reference marks indicating the loading conditions that require adjustment of the dipped-beam.

The number of positions on devices which are not continuously adjustable must be such as to ensure compliance with the range of values prescribed in paragraph 6.2.6.1.2 in all the loading conditions defined in Annex 5.

For these devices also, the loading conditions of Annex 5 that require adjustment of the dipped-beam shall be clearly marked near the control of the device (see Annex 8).

6.2.6.2.3.   In the event of a failure of devices described in paragraphs 6.2.6.2.1 and 6.2.6.2.2, the dipped-beam shall not assume a position in which the dip is less than it was at the time when the failure of the device occurred.

6.2.6.3.   Measuring procedure

6.2.6.3.2.   The measurement of the variation of dipped-beam inclination as a function of load must be carried out in accordance with the test procedure set out in Annex 6.

6.2.6.4.   Horizontal orientation

The horizontal orientation of one or both dipped-beam headlamps may be varied to produce bend lighting, provided that if the whole beam or the kink of the elbow of the cut-off is moved, the kink of the elbow of the cut-off shall not intersect the line of the trajectory of the centre of gravity of the vehicle at distances from the front of the vehicle which are larger than 100 times the mounting height of the respective dipped-beam headlamps.

6.2.7.   Electrical connections

The control for changing over to the dipped-beam must switch off all main-beam headlamps simultaneously.

The dipped-beam may remain switched on at the same time as the main beams.

In the case of dipped-beam headlamps according to Regulation No 98, the gas-discharge light sources shall remain switched on during the main-beam operation.

One additional light source, located inside the dipped-beam headlamps or in a lamp (except the main-beam headlamp) grouped or reciprocally incorporated with the respective dipped-beam headlamps, may be activated to produce bend lighting, provided that the horizontal radius of curvature of the trajectory of the centre of gravity of the vehicle is 500 m or less. This may be demonstrated by the manufacturer by calculation or by other means accepted by the authority responsible for type approval.

Dipped-beam headlamps may be switched ON or OFF automatically. However, it shall be always possible to switch these dipped-beam headlamps ON and OFF manually.

6.2.8.   Tell-tale

Tell-tale optional.

However, in the case where the whole beam or the kink of the elbow of the cut-off is moved to produce bend lighting, an operational tell-tale is mandatory; it shall be a flashing warning light which comes on in the event of a malfunction of the displacement of the kink of the elbow of the cut-off.

6.2.9.   Other requirements

ANNEX 6

MEASUREMENT OF THE VARIATION OF DIPPED-BEAM INCLINATION AS A FUNCTION OF LOAD

1.   SCOPE

This annex specifies a method for measuring variations in motor vehicle dipped-beam inclination, in relation to its initial inclination, caused by changes in vehicle attitude due to loading.

2.   DEFINITIONS

2.1.   Initial inclination

2.1.1.   Stated initial inclination

The value of the dipped-beam initial inclination specified by the motor vehicle manufacturer serving as a reference value for the calculation of permissible variations.

2.1.2.   Measured initial inclination

The mean value of dipped-beam inclination or vehicle inclination measured with the vehicle in condition No 1, as defined in Annex 5, for the category of vehicle under test. It serves as a reference value for the assessment of variations in beam inclination as the load varies.

2.2.   Dipped-beam inclination

It may be defined as follows:

| | either as the angle, expressed in milliradians, between the direction of the beam towards a characteristic point on the horizontal part of the cut-off in the luminous distribution of the headlamp and the horizontal plane, |
| --- | --- |

either as the angle, expressed in milliradians, between the direction of the beam towards a characteristic point on the horizontal part of the cut-off in the luminous distribution of the headlamp and the horizontal plane,

| | or by the tangent of that angle, expressed in percentage inclination, since the angles are small (for these small angles, 1 % is equal to 10 mrad). |
| --- | --- |

or by the tangent of that angle, expressed in percentage inclination, since the angles are small (for these small angles, 1 % is equal to 10 mrad).

If the inclination is expressed in percentage inclination, it can be calculated by means of the following formula:

Formula

where:

| h1 | is the height above the ground, in millimetres, of the above mentioned characteristic point, measured on a vertical screen perpendicular to the vehicle longitudinal median plane, placed at a horizontal distance L. |
| --- | --- |
| h2 | is the height above the ground, in millimetres, of the centre of reference (which is taken to be the nominal origin of the characteristic point chosen in h1): |
| L | is the distance, in millimetres, from the screen to the centre of reference. |

h1

is the height above the ground, in millimetres, of the above mentioned characteristic point, measured on a vertical screen perpendicular to the vehicle longitudinal median plane, placed at a horizontal distance L.

h2

is the height above the ground, in millimetres, of the centre of reference (which is taken to be the nominal origin of the characteristic point chosen in h1):

L

is the distance, in millimetres, from the screen to the centre of reference.

Negative values denote downward inclination (see figure 1).

Positive values denote upward inclination.

Notes:

| 1. | This drawing represents a category M1 vehicle, but the principle shown applies equally to vehicles of other categories. |
| --- | --- |

1.

| 2. | Where the vehicle does not incorporate a headlamp levelling system, the variation in dipped-beam inclination is identical with the variation in the inclination of the vehicle itself. |
| --- | --- |

2.

3.   MEASUREMENT CONDITIONS

3.1.   If a visual inspection of the dipped-beam pattern on the screen or a photometric method is used, measurement shall be carried out in a dark environment (for example, a dark room) of sufficient area to allow the vehicle and the screen to be placed as shown in figure 1. Headlamp centres of reference shall be at a distance from the screen of at least 10 m.

3.2.   The ground on which measurements are made shall be as flat and horizontal as possible, so that the reproducibility of measurements of dipped-beam inclination can be assured with an accuracy of ± 0,5 mrad (± 0,05 % inclination).

3.3.   If a screen is used, its marking, position and orientation in relation to the ground and to the median longitudinal plane of the vehicle, shall be such that the reproducibility of the measurement of the dipped-beam inclination can be assured with an accuracy of ± 0,5 mrad (± 0,05 % inclination).

3.4.   During measurements, the ambient temperature shall be between 10 and 30 °C.

4.   VEHICLE PREPARATION

4.1.   Measurements shall be carried out on a vehicle which has travelled a distance of between 1 000 km and 10 000 km, preferably 5 000 km.

4.2.   Tyres shall be inflated to the full-load pressure specified by the vehicle manufacturer. The vehicle shall be fully replenished (fuel, water, oil) and equipped with all the accessories and tools specified by the manufacturer. Full fuel replenishment means that the fuel tank must be filled to not less than 90 % of its capacity.

4.3.   The vehicle shall have the parking brake released and the gearbox in neutral.

4.4.   The vehicle shall be conditioned for at least 8 h at the temperature specified in paragraph 3.4.

4.5.   If a photometric or visual method is used, headlamps with a well-defined dipped-beam cut-off should preferably be installed on the vehicle under test in order to facilitate the measurements. Other means are allowed to obtain a more precise reading (for example, removal of the headlamp lens).

5.   TEST PROCEDURE

5.1.   General

The variations in either dipped-beam or vehicle inclination, depending on the method chosen, shall be measured separately for each side of the vehicle. The results obtained from both left and right headlamps under all the load conditions specified in Annex 5, shall be within the limits set out in paragraph 5.5. The load shall be applied gradually without subjecting the vehicle to excessive shocks.

5.2.   Determination of the measured initial inclination

The vehicle shall be prepared as specified in paragraph 4 and laden as specified in Annex 5 (first loading condition of the respective vehicle category). Before each measurement, the vehicle shall be rocked as specified in paragraph 5.4. Measurements shall be made three times.

5.2.1.   If none of the three measured results differ by more than 2 mrad (0,2 % inclination) from the arithmetic mean of the results, that mean shall constitute the final result.

5.2.2.   If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 % inclination), a further series of 10 measurements shall be made, the arithmetic mean of which shall constitute the final result.

5.3.   Measurement methods

Any method may be used to measure variations of inclination provided that the readings are accurate to within ± 0,2 mrad (± 0,02 % inclination).

5.4.   Treatment of vehicle in each loading condition

The vehicle suspension and any other part likely to affect dipped-beam inclination shall be activated according to the methods described below.

However, the technical authorities and manufacturers may jointly propose other methods (either experimental or based upon calculations), especially when the test poses particular problems, provided such calculations are clearly valid.

5.4.1.   M1 category vehicles with conventional suspension

With the vehicle standing on the measuring site and, if necessary, with the wheels resting on floating platforms (which must be used if their absence would lead to restriction of the suspension movement likely to affect the results of measurements), rock the vehicle continuously for at least three complete cycles, for each cycle, first the rear and than the front end of the vehicle is pushed down.

The rocking sequence shall end with the completion of a cycle. Before making the measurements, the vehicle shall be allowed to come to rest spontaneously. Instead of using floating platforms, the same effect can be achieved by moving the vehicle backwards and forwards for at least a complete wheel revolution.

5.4.2.   M2, M3 and N category vehicles with conventional suspension

5.4.2.1.   If the treatment method for category M1 vehicles described in paragraph 5.4.1 is not possible, the method described in paragraphs 5.4.2.2 or 5.4.2.3 may be used.

5.4.2.2.   With the vehicle standing on the measuring site and the wheels on the ground, rock the vehicle by temporarily varying the load.

5.4.2.3.   With the vehicle standing on the measuring site and the wheels on the ground, activate the vehicle suspension and all other parts which may affect the dipped-beam inclination by using a vibration rig. This can be a vibrating platform on which the wheels rest.

5.4.3.   Vehicles with non-conventional suspension, where the engine has to be running

Before making any measurement wait until the vehicle has assumed its final attitude with the engine running.

5.5.   Measurements

The variation of the inclination of the dipped-beam shall be assessed for each of the different loading conditions in relation to the measured initial inclination determined in accordance with paragraph 5.2.

If the vehicle is fitted with a manual headlamp-levelling system, the latter shall be adjusted to the positions specified by the manufacturer for given loading conditions (according to Annex 5).

5.5.1.   To begin with, a single measurement shall be made in each loading condition. Requirements have been met if, for all the loading conditions, the variation in inclination is within the calculated limits (for example, within the difference between the stated initial inclination and the lower and upper limits specified for approval) with a safety margin of 4 mrad (0,4 % inclination).

5.5.2.   If the result(s) of any measurement(s) does (do) not lie within the safety margin indicated in paragraph 5.5.1 or exceed(s) the limit values, a further three measurements shall be made in the loading conditions corresponding to this (these) result(s) as specified in paragraph 5.5.3.

5.5.3.   For each of the above loading conditions:

| 5.5.3.1. | If none of the three measured results differs by more than 2 mrad (0,2 % inclination) from the arithmetic mean of the results, that mean shall constitute the final result. |
| --- | --- |

5.5.3.1.

If none of the three measured results differs by more than 2 mrad (0,2 % inclination) from the arithmetic mean of the results, that mean shall constitute the final result.

| 5.5.3.2. | If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 % inclination), a further series of 10 measurements shall be made, the arithmetic mean of which shall constitute the final result. |
| --- | --- |

5.5.3.2.

If any measurement differs from the arithmetic mean of the results by more than 2 mrad (0,2 % inclination), a further series of 10 measurements shall be made, the arithmetic mean of which shall constitute the final result.

| 5.5.3.3. | If a vehicle is fitted with an automatic headlamp-levelling system which has an inherent hysteresis loop, average results at the top and bottom of the hysteresis loop shall be taken as significant values. |
| --- | --- |

5.5.3.3.

If a vehicle is fitted with an automatic headlamp-levelling system which has an inherent hysteresis loop, average results at the top and bottom of the hysteresis loop shall be taken as significant values.

All these measurements shall be made in accordance with paragraphs 5.5.3.1 and 5.5.3.2.

5.5.4.   Requirements have been met, if, under all loading conditions, the variation between the measured initial inclination determined in accordance with paragraph 5.2 and the inclination measured under each loading condition is less than the values calculated in paragraph 5.5.1 (without safety margin).

5.5.5.   If only one of the calculated upper or lower limits of variation is exceeded, the manufacturer shall be permitted to choose a different value for the stated initial inclination, within the limits specified for approval.

2.   CONDITIONS OF MEASUREMENT

2.1.   Site

2.1.1.   The test site must consist of a central acceleration section surrounded by a substantially flat test area.

The acceleration section must be level; the track surface must be dry and such that rolling noise remains low.

The test track must be such that the conditions of a free sound field between the sound source and the microphone are attained to within 1 dB. This condition shall be deemed to be met if there are no large sound-reflecting objects such as fences, rocks, bridges or buildings within 50 m of the centre of the acceleration section. The surface of the site must be in accordance with the provisions given in Annex 8 to this Regulation and be free of powdery snow, tall grass, loose soil or cinders. There must 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 must so position himself as not to affect the readings of the measuring instrument.

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

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

2.1.2.1.   The meteorological instrumentation should be positioned adjacent to the test area at a height of 1,2 ± 0,1 m.

The measurements shall be made when the ambient air temperature is within the range from 0 °C to 40 °C.

Tests shall not be carried out if the wind speed, including gusts, at microphone height exceeds 5 m/s, during the sound measurement interval and shall be recorded during each test run.

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

2.1.3.   The A-weighted sound level of sound sources other than those of the vehicle to be tested and of wind effects must be at least 10 dB(A) below the sound level produced by the vehicle.

2.2.   Vehicle

2.2.1.   Measurements shall be made on unladen vehicles and, except in the case of non-separable vehicles, without trailer or semi-trailer.

2.2.2.   The tyres used for the test are selected by the vehicle manufacturer and shall comply with commercial practice and be available on the market; they shall correspond to one of the tyre sizes designated for the vehicle by the vehicle manufacturer and meet the minimum tread depth of 1,6 mm in the main grooves of the tread surface.

The tyres must be inflated to the pressure(s) appropriate to the test mass of the vehicle.

2.2.5.   If the vehicle is fitted with fan(s) having an automatic actuating mechanism, this system must not be interfered with during the measurements.

2.2.6.   If the vehicle is equipped with an exhaust system containing fibrous materials, the exhaust system is to be conditioned before the test according to Annex 5.

3.   METHODS OF TESTING

3.1.   Measurement of noise of vehicles in motion

3.1.1.   General conditions of test (see Appendix, figure 1)

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

3.1.1.2.   The microphone must be located at a distance of 7,5 ± 0,2 m from the reference line CC’ (Figure 1) of the track and 1,2 ± 0,1 m above the ground. Its axis of maximum sensitivity must be horizontal and perpendicular to the path of the vehicle (line CC’).

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

The vehicle shall be driven in a straight line over the acceleration section in such a way that the longitudinal median plane of the vehicle is as close as possible to the line CC’ and approach line AA’ at a steady speed as specified below. When the front of the vehicle reaches the line AA’, the throttle shall be fully opened as rapidly as practicable and held in the fully-opened position until the rear of the vehicle crosses line BB’; the throttle shall then be closed again as rapidly as possible.

3.1.1.4.   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.

3.1.1.5.   The maximum sound level expressed in A-weighted decibels (dB(A)) shall be measured as the vehicle is driven between lines AA’ and BB’. Such value shall constitute the result of the measurement.

3.1.2.   Determination of the approach speed

3.1.2.1.   Symbols used

The letter symbols used in this paragraph have the following meaning:

| S | : | engine rotation speed as indicated under item 5.4 of Annex 1. |
| --- | --- | --- |
| NA | : | uniform engine rotational speed at the approach of line AA’. |
| VA | : | uniform vehicle speed at the approach of line AA’. |
| Vmax | : | maximum speed declared by the vehicle manufacturer. |

S

:

engine rotation speed as indicated under item 5.4 of Annex 1.

NA

:

uniform engine rotational speed at the approach of line AA’.

VA

:

uniform vehicle speed at the approach of line AA’.

Vmax

:

maximum speed declared by the vehicle manufacturer.

3.1.2.2.   Vehicle with no gearbox

For vehicles with no gearbox or with no transmission control, the uniform speed at the approach of line AA’ will be such that:

either VA = 50 km/h;

or VA corresponding to NA = 3/4 S and VA ≤ 50 km/h

in the case of vehicles of category M1 and in the case of vehicles of categories other than M1, having an engine power not greater than 225 kW (ECE);

or VA corresponding to NA = 1/2 S and VA ≤ 50 km/h

in the case of vehicles not belonging to category M1 having an engine power greater than 225 kW (ECE);

or, in the case of vehicles powered by an electric motor

Formula
  or VA = 50 km/h,

whichever is the lower.

3.1.2.3.   Vehicle with a manually-operated gearbox

3.1.2.3.1.   Approach speed

The vehicle shall approach the line AA' at a steady speed with a tolerance ± 1 km/h; except where the controlling factor is engine speed the tolerance shall be the larger of ± 2 % or ± 50 min-1, such that:

either VA = 50 km/h;

or VA corresponding to NA = 3/4 S and VA ≤ 50 km/h

in the case of vehicles of category M1 and in the case of vehicles of categories other than M1, having an engine power not greater than 225 kW (ECE);

or VA corresponding to NA = 1/2 S and VA ≤ 50 km/h

in the case of vehicles not belonging to category M1 having an engine power greater than 225 kW (ECE);

or, in the case of vehicles powered by an electric motor

Formula
  or VA = 50 km/h,

whichever is the lower.

3.1.2.3.2.   Choice of the gear ratio

3.1.2.3.2.1.   Vehicles of categories M1 and N1
   (1) fitted with a gearbox having four or less forward gears shall be tested in second gear.

3.1.2.3.2.2.   Vehicles of categories M1 and N1
   (1) fitted with a gearbox having more than four forward gears shall be tested successively in second and third gear. The average value of the sound levels recorded for these two conditions shall be calculated.

However, vehicles of category M1 having more than four forward gears and equipped with an engine developing a maximum power greater than 140 kW (ECE) and a permissible maximum-power/maximum-mass ratio greater than 75 kW (ECE)/t shall be tested only in third gear, provided that the speed at which the rear of the vehicle passes the line BB’ in third gear is greater than 61 km/h.

If during the test in second gear, the engine speed exceeds the engine speed, S, at which the engine develops its rated maximum power, the test must be repeated with an approach speed and/or approach engine speed reduced by steps of 5 % S, until the engine speed attained no longer exceeds S.

If the engine speed S is still attained with an approach speed corresponding to the idle speed, then the test will be performed only in third gear and the relevant results have to be evaluated.

3.1.2.3.2.3.   Vehicles of categories other than M1 and N1, in which the total number of forward gear ratios is x (including those obtained by way of an auxiliary transmission or a multi-gear axle) will be tested sequentially, using the ratio equal to or higher than x/n (2)
   (3).

Initial testing will be carried out using the ratio which is gear (x/n) or the next higher gear ratio if (x/n) is not an integer. The testing shall continue from the gear (x/n) to the next higher gear.

Shifting up gear ratios from (x/n) shall be terminating when in the gear X in which the rated engine speed is reached just before the rear of the vehicle has passed the line BB’.

Sample calculation for testing: There are 16 forward ratios for drive train having a transmission with eight gears and an auxiliary transmission with two gears. If the engine has 230 kW then (x/n) = (8 × 2)/3 = 16/3 = 5 1/3. The initial test gear ratio is sixth (includes the gears from both the main transmission and auxiliary which is sixth out of the 16 total gear ratios), with the next gear ratio is seventh up to ratio X.

In the case of vehicles having different overall gear ratios the representative of the vehicle type by the test vehicle is determined as follows:

| | if the highest sound level is obtained between the ratio x/n and ratio X the vehicle shall be deemed representative of its type; |
| --- | --- |

if the highest sound level is obtained between the ratio x/n and ratio X the vehicle shall be deemed representative of its type;

| | if the highest sound level is obtained at ratio x/n the vehicle selected shall be deemed representative of its type only for those vehicles which have a lower overall gear ratio at x/n; |
| --- | --- |

if the highest sound level is obtained at ratio x/n the vehicle selected shall be deemed representative of its type only for those vehicles which have a lower overall gear ratio at x/n;

| | if the highest sound level is obtained at ratio X the vehicle selected shall be deemed representative of its type only for those vehicles which have a higher overall gear ratio than the gear ratio X. |
| --- | --- |

if the highest sound level is obtained at ratio X the vehicle selected shall be deemed representative of its type only for those vehicles which have a higher overall gear ratio than the gear ratio X.

However the vehicle is deemed representative of its type also, if at the applicant's request the tests are extended over more ratios than foreseen, and the highest sound level is obtained between the extreme ratios tested.

3.1.2.4.   Automatic transmission (4)

3.1.2.4.1.   Vehicles without a manual selector

3.1.2.4.1.1.   Approach speed

The vehicle shall approach the line AA’ at various uniform speeds of 30, 40, 50 km/h or at 3/4 of the maximum on-road speed if this value is lower.

If the vehicle is equipped with an automatic transmission which cannot be tested with the procedure outlined in the subsequent sections, it shall be tested at different approach speeds, namely 30 km/h, 40 km/h, and 50 km/h, or at three quarters of maximum vehicle speed as specified by the manufacturer if this value is lower. The condition giving the highest noise level shall be retained.

3.1.2.4.2.   Vehicles equipped with a manual selector with X positions

3.1.2.4.2.1.   Approach speed

The vehicle shall approach the line AA’ at a steady speed corresponding to the lower of the following velocities with a tolerance ± 1 km/h; except where the controlling factor is engine speed the tolerance shall be the larger of ± 2 % or ± 50 rpm, such that:

either VA = 50 km/h;

or VA corresponding to NA = 3/4 S and VA ≤ 50 km/h

in the case of vehicles of category M1 and in the case of vehicles of categories other than M1, having an engine power not greater than 225 kW (ECE);

or VA corresponding to NA = 1/2 S and VA ≤ 50 km/h

in the case of vehicles not belonging to category M1 having an engine power greater than 225 kW (ECE);

or, in the case of vehicles powered by an electric motor

Formula
  or VA = 50 km/h,

whichever is the lower.

However, if during the test, in the case of vehicles having more than two separate gears, there is an automatic downshift to first gear, this downshift may be avoided, at the manufacturer's choice, according to paragraph 3.1.2.4.2.4.

3.1.2.4.2.2.   Position of the manual selector

The test shall be conducted with the selector in the position recommended by the manufacturer for ‘normal’ driving. External downshifting (for example kickdown) shall be excluded.

3.1.2.4.2.3.   Auxiliary gears

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 special selector’s positions for slow movements, parking, or braking shall be excluded.

3.1.2.4.2.4.   Prevention of downshift

Some vehicles equipped with an automatic transmission (two or more discrete ratios) may downshift to a gear ratio not normally used in urban driving, as defined by the manufacturer. A gear ratio not used for urban driving includes a gear ratio intended for slow movement, parking or braking. In these cases the operator may select any of the following modifications:

| (a) | increase the vehicle speed v to a maximum of 60 km/h in order to avoid such a change down; |
| --- | --- |

(a)

increase the vehicle speed v to a maximum of 60 km/h in order to avoid such a change down;

| (b) | maintain the vehicle speed v at 50 km/h and limit the fuel supply to the engine to 95 % of the supply necessary for full load; this condition is considered to be satisfied;






  (i) | in the case of a spark-ignition engine, when the angle of the throttle opening is 90 % of the full angle; |
| --- | --- | --- |

(b)

maintain the vehicle speed v at 50 km/h and limit the fuel supply to the engine to 95 % of the supply necessary for full load; this condition is considered to be satisfied;

(i)

in the case of a spark-ignition engine, when the angle of the throttle opening is 90 % of the full angle;

| (ii) | in the case of a compression-ignition engine, when the fuel supply to the injection pump is limited to 90 % of its maximum supply; |
| --- | --- |

(ii)

in the case of a compression-ignition engine, when the fuel supply to the injection pump is limited to 90 % of its maximum supply;

| (c) | establish and use an electronic control that will prevent a downshift to gears lower than those used in normal urban driving as defined by the manufacturer. |
| --- | --- |

(c)

establish and use an electronic control that will prevent a downshift to gears lower than those used in normal urban driving as defined by the manufacturer.

3.1.3.   Interpretation of results

The measurement of noise emitted by the vehicle in motion shall be considered valid if the difference between the two consecutive measurements on the same side of the vehicle is not more than 2 dB(A) (5).

The figure recorded shall be that corresponding to the highest sound level. Should that figure exceed by more than 1 dB(A) the maximum sound level authorised for the category of vehicle tested, a second series of two measurements at the corresponding microphone position shall be made. Three out of the four results so obtained in this second position must fall within the prescribed limits.

To allow for lack of precision in the measuring instrument the figures read from it during measurement shall each be reduced by 1 dB(a).

3.2.   Measurement of noise emitted by stationary vehicles

3.2.1.   Sound level in the vicinity of vehicles

In order to facilitate subsequent checks on vehicles in use, the sound level must be measured close to the exhaust system outlet in accordance with the following requirements and the measurement results entered in the test report drawn up for the purpose of issuing the certificate referred to in Annex 1.

3.2.2.   Acoustic measurements

A precision sound level meter as defined in paragraph 1.1 of this Annex must be used for the measurements.

3.2.3.   Test site — local conditions (Figure 2)

3.2.3.1.   Measurements should be made on a stationary vehicle in an area which corresponds to that for measurements of vehicles in motion and therefore corresponds to the provisions given in Annex 8 to this Regulation.

3.2.3.2.   During the test nobody shall be in the measurement area, except the observer and the driver whose presence must have no influence on the meter reading.

3.2.4.   Disturbance noise and wind interference

Readings on the measuring instruments produced by ambient noise and wind must 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.

3.2.5.   Measuring method

3.2.5.1.   Nature and number of measurements

The maximum sound level expressed in A-weighted decibels (dB(A)) must be measured during the operating period referred to in paragraph 3.2.5.3.2.1.

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

3.2.5.2.   Positioning and preparation of the vehicle

The vehicle shall be located in the centre part of the test area with the gear level in 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 must be brought to its normal operating condition, as specified by the manufacturer.

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

3.2.5.3.   Measuring of noise in proximity to the exhaust (see Appendix, Figure 2)

3.2.5.3.1.   Positions of the microphone

3.2.5.3.1.1.   The height of the microphone above the ground should be equal to that of the outlet pipe of the exhaust gases, but in any event shall be limited to a minimum value of 0,2 m.

3.2.5.3.1.2.   The microphone must be pointed towards the orifice of the gas flow and located at a distance of 0,5 m from the latter.

3.2.5.3.1.3.   Its axis of maximum sensitivity must be parallel to the ground and must make an angle of 45° ± 10° with the vertical plane containing the direction of the gas flow. The instructions of the manufacturer of the sound level meter with regard to this axis must be respected. In relation to this plane, the microphone shall be placed in such a way as to obtain the maximum distance from the longitudinal median plane of the vehicle; in case of doubt, the position which gives the maximum distance from the contour of the vehicle shall be selected.

3.2.5.3.1.4.   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 is 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.

3.2.5.3.1.5.   For vehicles with a vertical exhaust (e.g. commercial vehicles) the microphone should be placed at the height of the exhaust outlet. Its axis should be vertical and oriented upwards. It should be placed at a distance of 0,5 m from the side of the vehicle nearest to the exhaust.

3.2.5.3.1.6.   For vehicles having an exhaust provided with outlets spaced more than 0,3 m apart, one measurement is made for each outlet as if it were the only one, and the highest level is noted.

3.2.5.3.2.   Operating conditions of the engine

ANNEX 6

COMPRESSED AIR NOISE

1.   METHOD OF MEASUREMENT

The measurement is performed at microphone positions 2 and 6 according to Figure 1, with the vehicle stationary. The highest A-weighted noise level is 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 noise 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 noise limit.

3.   LIMITING VALUE

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

Appendix to Annex 6

ANNEX 8

SPECIFICATIONS FOR THE TEST SITE

1.   INTRODUCTION

This Annex describes the specifications relating to the physical characteristics and the laying of the test track. These specifications based on a special standard (1) describe the required physical characteristics as well as the test methods for these characteristics.

2.   REQUIRED CHARACTERISTICS OF THE SURFACE

A surface is considered to conform to this standard provided that the texture and voids content or sound absorption coefficient have been measured and found to fulfil all the requirements of paragraphs 2.1 to 2.4 and provided that the design requirements (paragraph 3.2) have been met.

2.1.   Residual voids content

The residual voids content, VC, of the test track paving mixture shall not exceed 8 %. For the measurement procedure, see paragraph 4.1.

2.2.   Sound absorption coefficient

If the surface fails to comply with the residual voids content requirement, the surface is acceptable only if its sound absorption coefficient, α ≤ 0,10. For the measurement procedure, see paragraph 4.2. The requirement of paragraphs 2.1 and 2.2 is met also if only sound absorption has been measured and found to be α ≤ 0,10.

Note: The most relevant characteristic is the sound absorption, although the residual voids content is more familiar among road constructors. However, sound absorption needs to be measured only if the surface fails to comply with the voids requirement. This is motivated because the latter is connected with relatively large uncertainties in terms of both measurements and relevance and some surfaces therefore erroneously may be rejected when based only on the voids measurement.

2.3.   Texture depth

The texture depth (TD) measured according to the volumetric method (see paragraph 4.3) shall be:

TD ≥ 0,4 mm

2.4.   Homogeneity of the surface

Every practical effort shall be taken to ensure that the surface is made to be as homogeneous as possible within the test area. This includes the texture and voids content, but it should also be observed that if the rolling process results in more effective rolling at some places than others, the texture may be different and unevenness causing bumps may also occur.

2.5.   Period of testing

In order to check whether the surface continues to conform to the texture and voids content or sound absorption requirements stipulated in this standard, periodic testing of the surface shall be done at the following intervals:

| (a) | For residual voids content or sound absorption: | when the surface is new; |
| --- | --- | --- |

(a)

For residual voids content or sound absorption:

when the surface is new;

| | if the surface meets the requirements when new, no further periodical testing is required. If it does not meet the requirement when it is new, it may do later because surfaces tend to become clogged and compacted with time. |
| --- | --- |

if the surface meets the requirements when new, no further periodical testing is required. If it does not meet the requirement when it is new, it may do later because surfaces tend to become clogged and compacted with time.

| (b) | For texture depth (TD): | when the surface is new; |
| --- | --- | --- |

(b)

For texture depth (TD):

when the surface is new;

| | when the noise testing starts (NB: not before four weeks after laying); |
| --- | --- |

when the noise testing starts (NB: not before four weeks after laying);

| | then every 12 months. |
| --- | --- |

then every 12 months.

3.   TEST SURFACE DESIGN

3.1.   Area

When designing the test track layout it is important to ensure that, as a minimum requirement, the area traversed by the vehicles running through the test strip is covered with the specified test material with suitable margins for safe and practical driving. This will require that the width of the track is at least 3 m and the length of the track extends beyond lines AA and BB by at least 10 m at either end. Figure 1 shows a plan of a suitable test site and indicates the minimum area which shall be machine laid and machine compacted with the specified test surface material. According to Annex 3, paragraph 3.1.1.1, measurements have to be made on each side of the vehicle. This can be made either by measuring with two microphone locations (one on each side of the track) and driving in one direction, or measuring with a microphone only on one side of the track but driving the vehicle in two directions. If the latter method is used, then there are no surface requirements on that side of the track where there is no microphone.

P (% passing) = 100 × (d/dmax)1/2

where:

| d | = | square mesh sieve size, in mm |

4.   TEST METHOD

4.1.   Measurement of the residual voids content

For the purpose of this measurement, cores have to be taken from the track in at least four different positions which are equally distributed in the test area between lines AA and BB (see Figure 1). In order to avoid inhomogeneity and unevenness in the wheel tracks, cores should not be taken in wheel tracks themselves, but close to them. Two cores (minimum) should be taken close to the wheel tracks and one core (minimum) should be taken approximately midway between the wheel tracks and each microphone location.

If there is a suspicion that the condition of homogeneity is not met (see paragraph 2.4.), cores shall be taken from more locations within the test area.

The residual voids content has to be determined for each core, then the average value from all cores shall be calculated and compared with the requirement of paragraph 2.1. In addition, no single core shall have a voids value which is higher than 10 %. The test surface constructor is reminded of the problem which may arise when the test area is heated by pipes or electrical wires and cores must be taken from this area. Such installations must be carefully planned with respect to future core drilling locations. It is recommended to leave a few locations of size approximately 200 × 300 mm where there are no wires/pipes or where the latter are located deep enough in order not to be damaged by cores taken from the surface layer.

4.2.   Sound absorption coefficient

The sound absorption coefficient (normal incidence) shall be measured by the impedance tube method using the procedure specified in ISO 10534-1: ‘Acoustics — Determination of sound absorption coefficient and impedance by a tube method’
   (2).

Regarding test specimens, the same requirements shall be followed as regarding the residual voids content (see paragraph 4.1). The sound absorption shall be measured in the range between 400 Hz and 800 Hz and in the range between 800 Hz and 1 600 Hz (at least at the centre frequencies of third octave bands) and the maximum values shall be identified for both of these frequency ranges. Then these values, for all test cores, shall be averaged to constitute the final result.

4.3.   Volumetric macrotexture measurement

For the purpose of this standard, texture depth measurements shall be made on at least 10 positions evenly spaced along the wheel tracks of the test strip and the average value taken to compare with the specified minimum texture depth. See ISO 10844:1994 for the description of the procedure.

5.   STABILITY IN TIME AND MAINTENANCE

5.1.   Age influence

In common with any other surfaces, it is expected that the tyre/road noise level measured on the test surface may increase slightly during the first 6-12 months after construction.

The surface will achieve its required characteristics not earlier than four weeks after construction. The influence of age on the noise from trucks is generally less than that from cars.

The stability over time is determined mainly by the polishing and compaction by vehicles driving on the surface. It shall be periodically checked as stated in paragraph 2.5.

5.2.   Maintenance of the surface

Loose debris or dust which could significantly reduce the effective texture depth must be removed from the surface. In countries with winter climates, salt is sometimes used for de-icing. Salt may alter the surface temporarily or even permanently in such a way as to increase noise and is therefore not recommended.

5.3.   Repaving the test area

If it is necessary to repave the test track, it is usually unnecessary to repave more than the test strip (of 3 m width in Figure 1) where vehicles are driving, provided the test area outside the strip met the requirement of residual voids content or sound absorption when it was measured.

ANNEX 10

METHODS AND INSTRUMENTS FOR MEASURING THE NOISE MADE BY MOTOR VEHICLES (MEASUREMENT METHOD B)

1.   MEASURING INSTRUMENTS

1.1.   Acoustic measurements

The apparatus used for measuring the noise level must be a precision sound-level meter or equivalent measurement system meeting the requirements of class 1 instruments (inclusive of the recommended windscreen, if used). These 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 should be made at a time interval not greater than 30 ms.

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

1.2.   Compliance with requirements

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

1.3.   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 fulfils the requirements for sound calibrators of precision class 1 according to IEC 60942:2003. Without any further adjustment the difference between the readings shall be less than or equal to 0,5 dB. If this value is exceeded, the results of the measurements obtained after the previous satisfactory check shall be discarded.

1.4.   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 must meet specification limits of at least ± 0,2 km/h.

1.5.   Meteorological instrumentation

The test site shall be substantially level. The surface of the test track shall be dry. The test site shall be such that when a small omni-directional noise source is placed on its surface at the central point (intersection of the microphone line PP’ and the centre line of the vehicle lane CC’), deviations from hemispherical acoustic divergence shall not exceed ± 1 dB.

This condition is deemed to be satisfied if the following requirements are met:

| — | within a radius of 50 m from the centre of the track the space is free of large reflecting objects such as fences, rocks, bridges or buildings, |
| --- | --- |

—

within a radius of 50 m from the centre of the track the space is free of large reflecting objects such as fences, rocks, bridges or buildings,

| — | the test track and the surface of the site are dry and free from absorbing materials such as powdery snow, or loose debris, |
| --- | --- |

—

the test track and the surface of the site are dry and free from absorbing materials such as powdery snow, or loose debris,

| — | in the vicinity of the microphone, there are no obstacles that could influence the acoustical field and no person is positioned between the microphone and the noise source. The meter observer is positioned so as not to influence the meter reading. |
| --- | --- |

—

in the vicinity of the microphone, there are no obstacles that could influence the acoustical field and no person is positioned between the microphone and the noise source. The meter observer is positioned so as not to influence the meter reading.

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

The meteorological instrumentation should 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 within the range from 5 °C to 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 noise level of the vehicle shall be ignored in taking the readings.

The background noise shall be measured for 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), in order to calculate the test results the appropriate correction must be substracted from the readings on the noise-level meter, as in the following table:

| Difference between ambient noise and noise to be measured dB(A) | 10 | 11 | 12 | 13 | 14 | 15 |
| --- | --- | --- | --- | --- | --- | --- |

2.2.1.   The vehicle tested shall be selected in a way so that that all vehicles of the same type which are put on the market fulfil the requirements of this Regulation. Measurements shall be made without any trailer, except in the case of non-separable vehicles. Measurements shall be made on vehicles at the test mass mt specified according to the following table:

| Vehicle category | Vehicle test mass |

| 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 maximum mass allowed for the rear axle. The test mass must 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) |

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 (2). The tyres shall be inflated to the pressure recommended by the vehicle manufacturer for the test mass of the vehicle. The tyres shall have a tread depth of at least 80 % of the full tread depth.

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

2.2.4.   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.

2.2.5.   If the vehicle is fitted with fan(s) having an automatic actuating mechanism, this system shall not be interfered with during the measurements.

2.2.6.   If the vehicle is equipped with an exhaust system containing fibrous materials, the exhaust system is to be conditioned before the test according to Annex 5.

3.   METHODS OF TESTING

3.1.   Measurement of noise of vehicles in motion

3.1.1.   General conditions of test

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’.

3.1.2.   Specific test conditions for vehicles

3.1.2.1.   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, test it 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 according to the table of paragraph 2.2.1.

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

3.1.2.1.1.   Power to mass ratio index (PMR)

PMR is defined as follows:

PMR = (Pn / mt) × 1 000 kg/kW

The power to mass ratio index (PMR) is used for the calculation of acceleration.

3.1.2.1.2.   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 (3). The formulas 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 determination of 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.

3.1.2.1.2.1.   Calculation procedure for vehicles with manual transmission, automatic transmission, adaptive transmissions and transmissions with variable gear ratios (CVTs) tested with locked gear ratios:

| | awot test = ((vBB’/3,6)2 – (vAA’/3,6)2) / (2 × (20 + l)) |
| --- | --- |

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. |
| --- | --- |

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 vehicle and test data (see Annex 9).

3.1.2.1.2.2.   Calculation procedure for vehicles with automatic transmissions, adaptive transmissions and CVTs tested with non-locked gear ratios

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

If devices or measures described in paragraph 3.1.2.1.4.2, can be used to control transmission operation for the purpose of achieving test requirements, calculate awot test using the equation:

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

Pre-acceleration may be used.

If no devices or measures described in paragraph 3.1.2.1.4.2 are used, calculate awot test using the equation:

awot_testPP-BB = ((vBB’/3,6)2 – (vP’/3,6)2) / (2 × (10 + l))

Pre-acceleration shall not be used.

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

3.1.2.1.2.3.   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 aurban is defined by:

aurban = 0,63 × log10 (PMR) – 0,09

3.1.2.1.2.4.   Reference acceleration

The reference acceleration awot ref defines the required acceleration during the accelerated test on the test track. It is a function depending on the power-to-mass ratio of a vehicle. That function is different for specific vehicle categories.

The reference acceleration awot ref is defined by:

| awot ref = 1,59 × log10 (PMR) – 1.41 | for PMR ≥ 25 |
| --- | --- |
| awot ref = a urban = 0,63 × log10 (PMR) – 0,09 | for PMR < 25 |

awot ref = 1,59 × log10 (PMR) – 1.41

for PMR ≥ 25

awot ref = a urban = 0,63 × log10 (PMR) – 0,09

for PMR < 25

3.1.2.1.3.   Partial power factor kP

The partial power factor kP (see paragraph 3.1.3.1) 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 awot ref has to be used instead of a awot test (see paragraph 3.1.3.1).

3.1.2.1.4.   Gear ratio selection

The selection of gear ratios for the test depends on their specific acceleration potential awot under full throttle condition, according to 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). If the vehicle has different modes leading to valid accelerations, the vehicle manufacturer has to prove to the satisfaction of the technical service, that the vehicle is tested in the mode which achieves an acceleration being closest to a wot ref.

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

The following conditions for selection of gear ratios are possible:

| — | 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, |
| --- | --- |

—

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,

| — | 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 = (awot ref – awot (i+1)) / (awot (i) – awot (i+1)), |
| --- | --- |

—

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 = (awot ref – awot (i+1)) / (awot (i) – awot (i+1)),

| — | if the acceleration value of gear ratio i exceeds 2,0 m/s2, the first gear ratio shall be used that gives an acceleration below 2,0 m/s2 unless gear ratio i+1 provides acceleration less than aurban. In this case, two gears, i and i+1 shall be used, including the gear i with 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 part power factor kP instead of awot ref, |
| --- | --- |

—

if the acceleration value of gear ratio i exceeds 2,0 m/s2, the first gear ratio shall be used that gives an acceleration below 2,0 m/s2 unless gear ratio i+1 provides acceleration less than aurban. In this case, two gears, i and i+1 shall be used, including the gear i with 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 part power factor kP instead of awot ref,

| — | if the vehicle has a transmission in which there is only one selection for the gear ratio the acceleration test is carried out in this vehicle gear selection. The achieved acceleration is then used for the calculation of the part power factor kP instead of awot ref, |
| --- | --- |

—

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

| — | if rated engine speed is exceeded in a gear ratio before the vehicle passes BB’ the next higher gear shall be used. |
| --- | --- |

—

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

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

| | The acceleration value awot test shall be calculated as defined in paragraph 3.1.2.1.2.2. |
| --- | --- |

The acceleration value awot test shall be calculated as defined in paragraph 3.1.2.1.2.2.

| | 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. |
| --- | --- |

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 is 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. |
| --- | --- |

Therefore, it is 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. |
| --- | --- |

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. |
| --- | --- |

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

| | The achieved acceleration awot test is then used for the calculation of the partial power factor kP (see paragraph 3.1.2.1.3) instead awot ref. |
| --- | --- |

The achieved acceleration awot test is then used for the calculation of the partial power factor kP (see paragraph 3.1.2.1.3) instead awot ref.

3.1.2.1.5.   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 vehicle and test data (Annex 9). The technical service shall have the possibility of pretesting.

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.

3.1.2.1.6.   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.

3.1.2.2.   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 be ignored when considering 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 according to the table of paragraph 2.2.1.

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.

3.1.2.2.1.   Gear ratio selection

3.1.2.2.1.1.   Vehicles with manual transmissions

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

If more than one gear fulfils the target conditions select that gear which is closest to 35 km/h. 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 in any condition.

A stable acceleration condition shall be ensured. If a stable acceleration cannot be ensured in a gear, this gear has to be disregarded.

3.1.2.2.1.2.   Vehicles with automatic transmissions, adaptive transmissions and transmissions with variable gear ratio (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 is not allowed. A gear shifting to a gear ratio which is not used in urban traffic, at the specified test condition, shall be avoided. Therefore, it is 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 fulfil paragraph 3.1.2.2.1.1, the vehicle shall be tested using only the target vehicle speed. The target vehicle speed for the test is vBB’ = 35 km/h ± 5 km/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 must 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 noise level is that result which is related to the test with the highest engine speed obtained during the test from AA’ to BB’.

3.1.2.2.2.   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.

3.1.3.   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 paragraph 2.1), 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.

3.1.3.1.   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)) |
| --- | --- |

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

| | Lcrs rep = Lcrs(i+1) + k × (Lcrs (i) – Lcrs (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)) |
| --- | --- |

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

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

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

3.2.   Measurement of noise emitted by stationary vehicles

3.2.1.   Sound level in the vicinity of vehicles

The measurement results shall be entered into the test report referred to in Annex 9.

3.2.2.   Acoustic measurements

A precision sound-level meter, or equivalent measuring system, as defined in paragraph 1.1 of this Annex shall be used for the measurements.

3.2.3.   Test site — local conditions (see Appendix to Annex 3, Figure 1)

3.2.3.1.   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.

3.2.4.   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 paragraph 1.1 of this Annex).

3.2.5.   Measuring method

3.2.5.1.   Nature and number of measurements

The maximum sound level expressed in A-weighted decibels (dB(A)) shall be measured during the operating period referred to in paragraph 3.2.5.3.2.1.

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

3.2.5.2.   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 must be brought to its normal operating condition, as specified by the manufacturer.

If the vehicle is fitted with fan(s) 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.

3.2.5.3.   Measuring of noise in proximity to the exhaust (see Appendix to Annex 3, Figure 1)

3.2.5.3.1.   Positions of the microphone

3.2.5.3.1.1.   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 1, 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.

3.2.5.3.1.2.   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.

3.2.5.3.1.3.   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 is 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.

3.2.5.3.1.4.   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 2 m from the side of the vehicle nearest to the exhaust.

3.2.5.3.1.5.   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. The angularity requirement in paragraph 3.2.5.3.1.2 may not be met in some cases.

3.2.5.3.2.   Operating conditions of the engine

3.2.5.3.2.1.   Target engine speed

The target engine speed is defined as:

| — | 75 % of the engine speed S for vehicles with a rated engine speed ≤ 5 000 min-1 |
| --- | --- |

—

75 % of the engine speed S for vehicles with a rated engine speed ≤ 5 000 min-1

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

—

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. |
| --- | --- |

—

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

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

3.2.5.3.2.2.   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 noise level shall be measured during a period of operation consisting of a maintenance of constant engine speed of one second and throughout the entire deceleration period, the maximum sound-level meter reading, mathematically rounded to the first decimal place, is taken as the test value.

3.2.5.3.2.3.   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 one second.

3.2.6.   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 (see paragraph 2.1 except the specifications of the test site), 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, constitutes the final result.
