Intensity of forward facing parking lamps 2 60 7.1.2. Intensity of rearward facing parking lamps 2 30 7.1.3. 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. All light sources which are connected in series are considered to be one light source.

7.2. Outside the reference axis and within the angular fields defined in the diagrams in Annex 3 to this Regulation, the intensity of the light emitted by each of the two samples shall: 7.2.1. in each direction corresponding to the points in the luminous intensity distribution table reproduced in Annex 4 to this Regulation be not less than the value shown in the said table for the direction in question, expressed as a percentage of the minimum specified in paragraph 7.1; 7.2.2. in any direction within the space from which the light in question is visible, not exceed the maximum specified in paragraph 7.1; 7.2.3. however, a luminous intensity of 60 cd shall be permitted for parking lamps directed to the rear incorporated with stop lamps (see paragraph 7.1.2) below a plane forming an angle of 5° with and downward from the horizontal plane; 7.2.4. Moreover, 7.2.4.1. throughout the fields defined in Annex 3 the intensity of the light emitted shall be not less than 0,05 cd, 7.2.4.2. the requirements of paragraph 2.2 of Annex 4 on local variations of intensity shall be observed.

7.3. Annex 4 of this Regulation to which reference is made in paragraph 7.2.1, gives particulars of the methods of measurement to be used.

8. TEST PROCEDURE

All measurements shall be carried out with uncoloured standard filament lamps of the types prescribed for the device, adjusted to produce the normal luminous flux prescribed for those types of lamps.

8.1. All measurements on lamps equipped with non-replaceable light sources (filament lamps and other) shall be made at 6,75 V, 13,5 V or 28,0 V respectively. In the case of light sources supplied by a special power supply, the above test voltages shall be applied to the input terminals of that power supply. The test laboratory may require from the manufacturer the special power supply needed to supply the light sources.

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

9. COLOUR OF LIGHT EMITTED

The colour of the light emitted inside the field of the light distribution grid defined at paragraph 2 of Annex 4, measured by using a source of light with a colour temperature of 2 856 K, corresponding to illuminant A of the International Commission on Illumination (CIE), shall be red, white or amber. For testing see Annex 5 to this Regulation. 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 paragraph 8.1 of this Regulation.

10. REMARKS CONCERNING COLOURS

Every approval under this Regulation is, by virtue of paragraph 5 above, granted for a type of device emitting light of a particular colour or uncoloured light; the Contracting Parties to the Agreement to which this Regulation is annexed are accordingly not precluded by article 3 of that Agreement from prohibiting, for devices fitted on the vehicles registered by them certain colours provided for in this Regulation.

11. MODIFICATIONS OF A TYPE OF PARKING LAMP AND EXTENSION OF APPROVAL

11.1. Every modification of the type of parking lamp shall be notified to the administrative department which approved the type of parking lamp. The department may then either: 11.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the parking lamp still complies with the requirements; or 11.1.2. Require a further test report from the Technical Service responsible for conducting the tests.

11.2. Confirmation or refusal of approval, specifying the modification shall be communicated by the procedure specified in paragraph 5.4 above.

11.3. The Competent Authority issuing the extension of approval shall assign a series number to each communication form drawn up for such an extension.

ANNEX 1 COMMUNICATION (Maximum format: A4 (210 × 297 mm))

ANNEX 2 ARRANGEMENT OF APPROVAL MARK Light source modules MD E3 17325 The light source module bearing the identification code shown above has been approved together with a lamp approved in Italy (E3) under approval number 17325.

ANNEX 3 MINIMUM ANGLES REQUIRED FOR THE LIGHT DISTRIBUTION IN SPACE (1) In all cases, the minimum vertical angles of light distribution in space are 15° above and 15° below the horizontal except for lamps with a mounting height of equal to or less than 750 mm above the ground, for which they are 15° above and 5° below the horizontal. (1) The angles shown in these diagrams are correct for devices to be mounted on the right side of the vehicle. The arrows point to the front of the vehicles.

ANNEX 4 PHOTOMETRIC MEASUREMENTS 1. MEASUREMENT METHODS 1.1. During photometric measurements, stray reflections shall be prevented by appropriate masking. 1.2. Should the results of measurements be challenged, measurements shall be carried out in such a way as to meet the following requirements: 1.2.1. the distance of measurements 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 angular aperture of the receiver viewed 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 deemed to be satisfied if that requirement is met in a direction deviating by not more than 15’ 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 of the field of the reference axis specified by the manufacturer. 2. STANDARD LUMINOUS INTENSITY DISTRIBUTION TABLE Left Right 2.1. The direction H = 0° and V = 0° corresponds to the reference axis. (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 measurements, the minimum intensities as a percentage of the minimum required in the axis for each lamp (in the direction H = 0° and V = 0°). 2.2. Within the field of light distribution of paragraph 2, schematically shown as a grid, the light pattern should be substantially uniform in so far as the light intensity in each direction of a part of the field formed by the grid lines meets at least the lowest minimum percentage value being shown (available) on the grid lines surrounding the questioned direction. 2.3. However in the case where a device is intended to be installed at a mounting height of equal to or less than 750 mm above the ground, the photometric intensity is verified only up to an angle of 5° downwards. 3. PHOTOMETRIC MEASUREMENT OF LAMPS 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 paragraph 8.1. 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. 3.3. For any signalling lamp except those equipped with filament lamp(s), 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.

ANNEX 5 COLOUR OF LIGHT EMITTED: CHROMATICITY COORDINATES For checking those colorimetric characteristics, a source of light at a colour temperature of 2 854 K corresponding to illuminant A of the International Commission on Illumination (CIE) shall be used. 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 paragraph 8.1 of this Regulation.

ANNEX 6 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 and equipped with a standard filament lamp, or when the lamps are equipped with non-replaceable light sources (filament lamps or other), and when all measurements are made at 6,75 V, 13,5 V or 28,0 V 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 with when the lamp is equipped with a standard filament lamp, or for lamps equipped with non-replaceable light sources (filament lamps or other), when the colorimetric characteristics are verified with the light source present in the lamp. 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 4 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 12.1 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 7 (first sampling) would be 0,95.
