of the light on the surface of the plate does not exceed 82 degrees  at any point on the surface to be illuminated, this angle being measured from the extremity of the device's illuminating area which is furthest from the surface of the plate.  If there is more than one illuminating device, the foregoing requirement shall apply only to that part of the plate intended to be illuminated by the device concerned.

       The device must be so designed that no light is emitted directly towards the rear, with the exception of red light if the device is combined or grouped with a rear lamp.

       8. MEASURING PROCEDURE

       Luminance measurements shall be made on a piece of clean white blotting paper with a minimum diffuse reflection factor of 70%, of the same dimensions as the registration plate, placed in the position normally occupied by it and 2 mm in front of its holder. Luminance measurements shall be made perpendicularly to the surface of the paper, at the points shown in Annex 3 according to the type of plate for which the device is intended, each point representing a circular area 25 mm in diameter.

       9. PHOTOMETRIC CHARACTERISTICS

       At each of the points of measurement shown in Annex 3, the luminance B shall be at least equal to 2.5 cd/m2.

       The gradient of the luminance between the values B1 and B2, measured at any two points 1 and 2 selected from among those mentioned above, shall not exceed 2 x Bo/cm, Bo being the minimum luminance measured at the various points, that is to say:  ≤

       10. 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:

       10.1. Devices for the illumination of rear registration plates (henceforth called devices), approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraphs 5, 6 and 9 above. If there is more than one device necessary, then in the following text a device means a set of devices.

       10.2. The minimum requirements for conformity of production control procedures set forth in annex 6 to this Regulation shall be complied with.

       10.3. The minimum requirements for sampling by an inspector set forth in annex 7 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 in respect of an illuminating device pursuant to this Regulation may be withdrawn if
