After verification of the specifications in paragraphs 6.1. to 6.5. of this Regulation and the specifications of shape and dimensions (Annex 5), the ten samples shall be subjected to the heat resistance test (Annex 10) and one hour minimum after this test examined as to their colorimetric characteristics and CIL (Annex 7) for an angle of divergence of 20' and an illumination angle V = H = 0° or, if necessary, in the positions defined in Annex 7. The two retro-reflecting devices giving the minimum and maximum values shall then be fully tested as shown in Annex 7. These two samples shall be kept by the laboratories for any further checks which may be found necessary. |
