Interpretation of results. 2.1.3.1. In the case of all vehicles except those of categories M3, N2 and N3, the time t shall not exceed 20 seconds.
2.1.3.2. In the case of vehicles of categories M3, N2 and N3, the time t shall not exceed 30 seconds.
Interpretation of results. The safety glazing shall be considered satisfactory if the increase of haze of the test piece does not exceed 2 per cent.
Interpretation of results. A set of four samples for each chemical shall be tested; for each chemical, in case of glazing of Class L, one of these samples shall be cross-cut according to paragraph 13. of Annex 3. Three samples out of four, among which the cross-cut sample mentioned above when applicable, shall give satisfactory results for each chemical.
Interpretation of results. The test for resistance to temperature changes shall be considered to have given a satisfactory result if the test pieces do not show any evidence of cracking, clouding, separation of layers or other apparent deterioration.
Interpretation of results. For vehicles of categories M1 and M2 having a maximum authorized mass not exceeding 3,500 kg, and category N1 the maximum A-weighted sound pressure level indicated during each passage of the vehicle according to paragraphs 3.1.2.1.5. and 3.
Interpretation of results. 6.7.3.1. The test for resistance to high temperature shall be considered to give a positive result if bubbles or other defects are not formed more than 15 mm from an uncut edge or 25 mm from a cut edge of the test piece or sample or more than 10 mm away of any cracks which may occur during the test.
6.7.3.2. A set of test pieces or samples submitted for approval shall be considered satisfactory from the point of view of the test for resistance to high temperature if all the tests give a satisfactory result.
Interpretation of results. 6.3.3.1. The cross-cut test shall be considered to have given a satisfactory result if at least the cross-cut value Gt1 is met.
Interpretation of results. 2.4.1. The time t1 recorded for the least-favoured energy storage device shall not exceed:
Interpretation of results. 11.2.6.1. The test for resistance to chemical agents shall be considered to have given a satisfactory result if the sample does not exhibit any softening, tackiness, crazing or apparent loss of transparency.
11.2.6.2. A set of samples shall be considered satisfactory with regard to the test for resistance to chemical agents if one of the following conditions is met:
11.2.6.2.1. All the tests have given a satisfactory result;
11.2.6.2.2. One test having given an unsatisfactory result, a new series of tests carried out on a new set of samples has given a satisfactory result.
12. Flexibility test and fold test
Interpretation of results. 6.2.3.1. The resistance to the simulated weathering shall be considered to have given a satisfactory result if:
6.2.3.1.1. The light transmittance measured in accordance with Annex 3, paragraph 9.1. does not fall below 95 per cent of the pre-weathering value. Additionally, for windows which are required for driver visibility the value shall not fall below 70 per cent.
6.2.3.1.2. No bubbles or other visible decompositions, discolouration, milkiness or crazing shall occur during weathering.
