6. INTENSITY OF LIGHT EMITTED

6.1. Intensity of the light specifications for reversing lamps

6.1.1. The intensity of the light emitted by each of the two samples shall be not less than the minima and not greater than the maxima specified below and shall be measured in relation to the axis of reference in the directions shown below (expressed in degrees of angle with the axis of reference).

6.1.2. The intensity along the axis of reference shall be not less than 80 candelas.

6.1.3. The intensity of the light emitted in all directions in which the light can be observed shall not exceed:

300 candelas in directions in or above the horizontal plane;

and, in directions below the horizontal plane:

600 candelas between h-h and 5° D and 8 000 candelas below 5° D.

6.1.4. In every other direction of measurement shown in Annex 3 to this Regulation, the luminous intensity shall be not less than the minima specified in that annex.

However, in the case where the reversing lamp is intended to be installed on a vehicle exclusively in a pair of devices, the photometric intensity may be verified only up to an angle of 30° inwards where a photometric value of at least 25 cd shall be satisfied.

This condition shall be clearly explained in the application for approval and relating documents (see paragraph 2 of this Regulation).

Moreover, in the case where the type approval will be granted applying the condition above, a statement in paragraph 11 ‘Comments’ of the communication form (see Annex 1 to this Regulation), will inform that the device shall only be installed in a pair.

6.1.5. In the case of a single lamp containing more than one light source, the lamp shall comply with the minimum intensity required when any one light source has failed an when all light sources are illuminated the maximum intensities shall not be exceeded. A group of light sources, wired so that the failure of any one of them causes all of them to stop emitting light, shall be considered to be one light source.

6.2. Intensity of the light specifications for manoeuvring lamps

6.2.1. The intensity shall not exceed 500 candelas in all directions in which the light can be observed, when installed in any mounting position specified by the applicant.

6.2.2. The device must be so designed that the light emitted directly towards the side, the front or the rear of the vehicle does not exceed 0,5 cd within the angular field as defined below.

(a) The vertical minimum angle φ min (in degree) is: φ min = arctan (1-mounting height)/10; where h is the mounting height in m

(b) The vertical maximum angle φ max (in degree) is: φ max = φ min + 11,3.

The measurement shall be limited to a horizontal angle ranging from +90° to -90° with respect to the line which cuts the reference axis and which is perpendicular to the vertical longitudinal plane of the vehicle.

The measurement distance shall be in minimum 3 m.

7. TEST PROCEDURES

7.1. All measurements, photometric and colorimetric, shall be made:

7.1.1. In the case of a lamp with replaceable light source, if not supplied by an electronic light source control gear, with an uncoloured standard light source of the category prescribed for the device, supplied with the voltage:

(a) in the case of filament lamp(s), that is necessary to produce the reference luminous flux required for that category of filament lamp;

(b) in the case of LED light sources of 6,75 V, 13,5 V or 28,0 V; the luminous flux value produced shall be corrected. The correction factor is the ratio between the objective luminous flux and the mean value of the luminous flux found at the voltage applied.

7.1.2. In the case of a lamp equipped with non-replaceable light sources (filament lamps and other), at 6,75 V, 13,5 V or 28,0 V respectively.

7.1.3. In the case of a system that uses an electronic light source control gear, being part of the lamp (3) applying at the input terminals of the lamp the voltage declared by the manufacturer or, if not indicated, 6,75 V, 13,5 V or 28,0 V respectively.

7.1.4. In the case of a system that uses an electronic light source control gear not being part of the lamp the voltage declared by the manufacturer shall be applied to the input terminals of the lamp.

7.2. The Technical Service shall require from the manufacturer the light source control gear needed to supply the light source and the applicable functions.

7.3. The voltage to be applied to the lamp shall be indicated in the communication form, specified in Annex 1 of this Regulation.

7.4. For any lamp, except those equipped with filament lamps, the luminous intensities measured after one minute and after 30 minutes of operation, shall comply with the minimum and maximum requirements. The luminous intensity distribution after one minute of operation can be calculated from the luminous intensity distribution after 30 minutes of operation by applying at each test point the ratio of luminous intensities measured at HV after one minute and after 30 minutes of operation.

7.5. The limits of the apparent surface in the direction of the reference axis of a light-signalling device shall be determined.

8. COLOUR OF LIGHT EMITTED

In the case of reversing lamps the colour of the light emitted inside the field of the light distribution grid defined at paragraph 2 of Annex 3 shall be white.

In the case of manoeuvring lamps the colour of the light emitted inside the field of the whole light distribution shall be white.

To check these colorimetric characteristics, the test procedure described in paragraph 7 of this Regulation shall be applied. Outside this field no sharp variation of colour shall be observed.

However, for lamps equipped with non-replaceable light sources (filament lamps and other), the colorimetric characteristics should be verified with the light sources present in the lamp, in accordance with relevant subparagraphs of paragraph 7.1 of this Regulation.

9. CONFORMITY OF PRODUCTION

The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:

ANNEX 3 PHOTOMETRIC MEASUREMENTS 1. Measurement methods general 1.1. When photometric measurements are taken, stray reflections shall be avoided by appropriate masking. 1.2. In the event that the results of measurements are challenged, measurements shall be taken in such a way as to meet the following requirements: 1.2.1. The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable; 1.2.2. The measuring equipment shall be such that the angle subtended by the receiver from the reference centre of the light is between 10' and 1°; 1.2.3. The intensity requirement for a particular direction of observation shall be satisfied if the required intensity is obtained in a direction deviating by not more than one quarter of a degree from the direction of observation. 1.3. In the case where the device may be installed on the vehicle in more than one or in a field of different positions the photometric measurements shall be repeated for each position or for the extreme positions in the field of reference axis specified by the manufacturer. 2. For reversing lamps the measuring points expressed in degrees of angle with the axis of reference and values of the minimum intensities of the light emitted. 2.1. The directions H = 0° and V = 0° correspond to the axis of reference. On the vehicle they are horizontal, parallel to the median longitudinal plane of the vehicle and oriented in the required direction of visibility. They pass through the centre of reference. The values shown in the table give, for the various directions of measurement, the minimum intensities in cd. 2.2. If visual examination of a lamp appears to reveal substantial local variations of intensity, a check shall be made to ensure that no intensity measured between two of the directions of measurement referred to above is below 50 % of the lower minimum intensity of the two prescribed for these directions of measurement. 3. Photometric measurement of lamps equipped with several light sources The photometric performance shall be checked: 3.1. For non-replaceable light sources (filament lamps and other): With the light sources present in the lamp, in accordance with relevant subparagraphs of paragraph 7.1 of this Regulation. 3.2. For replaceable light source(s): When equipped with light source(s) at 6,75 V, 13,5 V or 28,0 V, the luminous intensity values produced shall be corrected. For filament lamps the correction factor is the ratio between the reference luminous flux and the mean value of the luminous flux found at the voltage applied (6,75 V, 13,5 V or 28,0 V). For LED light sources the correction factor is the ratio between the objective luminous flux and the mean value of the luminous flux found at the voltage applied (6,75 V, 13,5 V or 28,0 V). The actual luminous fluxes of each filament lamp and/or LED light source used shall not deviate more than 5 % from the mean value. Alternatively and in case of filament lamps only, a standard filament lamp may be used in turn, in each of the individual positions, operated at its reference flux, the individual measurements in each position being added together.

ANNEX 4 MINIMUM REQUIREMENTS FOR CONFORMITY OF PRODUCTION CONTROL PROCEDURES 1. General 1.1. The conformity requirements shall be considered satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation. 1.2. With respect to photometric performances, the conformity of mass-produced lamps shall not be contested if, when testing photometric performances of any lamp chosen at random according to paragraph 7 of this Regulation, respectively: 1.2.1. No measured value deviates unfavourably by more than 20 % from the values prescribed in this Regulation. 1.2.2. If, in the case of a lamp equipped with a replaceable light source and if results of the test described above do not meet the requirements, tests on lamps shall be repeated using another standard light source. 1.3. The chromaticity coordinates shall be complied when tested under conditions of paragraph 7 of this Regulation. 2. Minimum requirements for verification of conformity by the manufacturer For each type of lamp the holder of the approval mark shall carry out at least the following tests, at appropriate intervals. The tests shall be carried out in accordance with the provisions of this Regulation. If any sampling shows non-conformity with regard to the type of test concerned, further samples shall be taken and tested. The manufacturer shall take steps to ensure the conformity of the production concerned. 2.1. Nature of tests Tests of conformity in this Regulation shall cover the photometric and colorimetric characteristics. 2.2. Methods used in tests 2.2.1. Tests shall generally be carried out in accordance with the methods set out in this Regulation. 2.2.2. In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the competent Type Approval Authority responsible for approval tests. The manufacturer is responsible for proving that the applied methods are equivalent to those laid down in this Regulation. 2.2.3. The application of paragraphs 2.2.1 and 2.2.2 above requires regular calibration of test apparatus and its correlation with measurements made by a competent authority. 2.2.4. In all cases the reference methods shall be those of this Regulation, particularly for the purpose of administrative verification and sampling. 2.3. Nature of sampling Samples of lamps shall be selected at random from the production of a uniform batch. A uniform batch means a set of lamps of the same type, defined according to the production methods of the manufacturer. The assessment shall in general cover series production from individual factories. However, a manufacturer may group together records concerning the same type from several factories, provided these operate under the same quality system and quality management. 2.4. Measured and recorded photometric characteristics The sampled lamp shall be subjected to photometric measurements for the minimum values at the points listed in Annex 3 and the required chromaticity coordinates. 2.5. Criteria governing acceptability The manufacturer is responsible for carrying out a statistical study of the test results and for defining, in agreement with the competent Type Approval Authority, criteria governing the acceptability of his products in order to meet the specifications laid down for verification of conformity of products in paragraph 9.1 of this Regulation. The criteria governing the acceptability shall be such that, with a confidence level of 95 %, the minimum probability of passing a spot check in accordance with Annex 5 (first sampling) would be 0,95.
