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. HEAT RESISTANCE TEST

       8.1. The lamp must be subjected to a one-hour test of continuous operation following a warm-up period of 20 minutes.  The ambient temperature shall be 23 degrees +/- 5 degrees. The lamp used shall be a lamp of the category prescribed for the lamp, and shall be supplied with a current at a voltage such that it gives the specified average power at the corresponding test voltage.

       8.2. Where only the maximum power is specified, the test shall be carried out by regulating the voltage to obtain a power equal to 90 % of the specified power. The specified average or maximum power referred to above shall in all cases be chosen from the voltage range of 6, 12 or 24 V at which it reaches the highest value.

       8.3. After the lamp has been stabilized at the ambient temperature, no distortion, deformation, cracking or colour modification shall be perceptible.

       9. COLOUR OF LIGHT EMITTED

       The colour of the light emitted, which shall be measured by using a source of light at a colour temperature of 2854 degrees K,[*/] must lie within the limits of the following trichromatic co-ordinates:

       limit towards yellow: y < 0.335

       limit towards purple: z < 0.008

       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 7.1. of this Regulation.

       10. CONFORMITY OF PRODUCTION

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

       10.1. Lamps approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraphs 6. and 9. above.

       10.2. The minimum requirements for conformity of production control procedures set forth in annex 4 to this Regulation shall be complied with.

       10.3. The minimum requirements for sampling by an inspector set forth in annex 5 to this Regulation shall be complied with.

       10.4. The authority which has granted type approval may at any time verify the conformity control methods applied in each production facility. The normal frequency of these verifications shall be once every two years.

       11. PENALTIES FOR NON-CONFORMITY OF PRODUCTION

       11.1. The approval granted for a type of rear fog lamp may
