REQUIREMENTS FOR LAMPS INCORPORATING LENSES OF PLASTIC MATERIAL - TESTING OF LENS OR MATERIAL SAMPLES AND OF COMPLETE LAMPS -

          1. GENERAL SPECIFICATIONS
              1.                                     The samples supplied pursuant to paragraph 3.2.4 of this Regulation shall satisfy the specifications indicated in paragraphs 2.1 to 2.5 below.
              2.                                     The two samples of complete lamps supplied pursuant to paragraph 3.2.3 of this Regulation and incorporating lenses of plastic material shall, with regard to the lens material, satisfy the specifications indicated in paragraph 2.6 below.
              3.                                     The samples of lenses of plastic material or samples of material shall be subjected, with the reflector to which they are intended to be fitted (where applicable), to approval tests in the chronological order indicated in table A reproduced in appendix 1 to this annex.
              4.                                     However, if the lamp manufacturer can prove that the product has already passed the tests prescribed in paragraphs 2.1-2.5 below, or the equivalent tests pursuant to another Regulation, those tests need not be repeated; only the tests prescribed in appendix 1, table B, shall be mandatory.
          2. TESTS
              1.                                     Resistance to temperature changes
                  1.                               Tests
Three new samples (lenses) shall be subjected to five cycles of temperature and humidity (RH = relative humidity) change in accordance with the following programme: 3 hours at 40 degrees C +/- 2 degrees C and 85-95 % RH;
1 hour at 23 degrees C +/- 5 degrees C and 60-75 % RH;
15 hours at -30 degrees C +/- 2 degrees C;
1 hour at 23 degrees C +/- 5 degrees C and 60-75 % RH;
3 hours at 80 degrees C +/- 2 degrees C;
1 hour at 23 degrees C +/- 5 degrees C and 60-75 % RH;
Before this test, the samples shall be kept at 23 degrees C +/- 5 degrees C and 60-75 % RH for at least four hours.
Note: The periods of one hour at 23 degrees C +/- 5 degrees C shall include the periods of transition from one temperature to another which are needed in order to avoid thermal shock effects.

2.1.2.                              Photometric measurements
2.1.2.1.                        Method
Photometric measurements shall be carried out on the samples before and after the test. These measurements shall be made using a standard lamp, at the following points:
B 50 and 50 V for the passing beam of a passing lamp or a passing/driving lamp; Emax for the driving beam of a driving
