5.4.


In the case of replaceable filament lamp(s):






5.4.1.


Any category or categories of filament lamp(s) approved according to Regulation No 37 may be used, provided that no restriction on the use is made in Regulation No 37 and its series of amendments in force at the time of application for type approval.










5.4.2.


The design of the device shall be such that the filament lamp can be fixed in no other position but the correct one.










5.4.3.


The filament lamp holder shall conform to the characteristics given in IEC Publication 60061. The holder data sheet relevant to the category of filament lamp used, applies.








6.   INTENSITY OF LIGHT EMITTED








6.1.


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).












6.2.


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












6.3.


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.




















6.4.


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.












6.5.


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 and 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.




7.   TEST PROCEDURES








7.1.


All measurements, photometric and colorimetric, shall be made:






7.1.1.

ANNEX 3

PHOTOMETRIC MEASUREMENTS

1.   Measurement methods








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.   Measuring points expressed in degrees of angle with the axis of reference and values of the minimum intensities of the light emitted
TOP









= Minimum intensities in cd.








2.1.


The direction H = O° and V = O° corresponds to the axis of reference. On the vehicle it is horizontal, parallel to the median longitudinal plane of the vehicle and oriented in the required direction of visibility. It passes 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 per cent 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 filament lamps:
when equipped with filament lamps at 6,75 V, 13,5 V or 28,0 V, the luminous intensity values produced shall be corrected. 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). The actual luminous fluxes of each filament lamp used shall not deviate more than ± 5 per cent from the mean value. Alternatively 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

COLOUR OF WHITE LIGHT: CHROMATICITY COORDINATES

For checking the colorimetric characteristics, a source of light at a colour temperature of 2 854° K corresponding to illuminant A of the International Commission on Illumination (ICI) shall be used.
These colorimetric characteristics shall be measured under conditions described in paragraph 7 of this Regulation.
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.





ANNEX 5

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 per cent 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 filament lamp.
















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 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 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 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 per cent, the minimum probability of passing a spot check in accordance with Annex 6 (first sampling) would be 0,95.





ANNEX 6

MINIMUM REQUIREMENTS FOR SAMPLING BY AN INSPECTOR

1.   GENERAL








1.1.


The conformity requirements shall be considered satisfied from a mechanical and a geometric standpoint, in accordance with the requirements of this Regulation, if any, if the differences do not exceed inevitable manufacturing deviations.












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 per cent 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 filament lamp.










1.2.3.


Lamps with apparent defects are disregarded.
















1.3.


The chromaticity coordinates shall be complied when tested under conditions of paragraph 7. of this Regulation.
