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.
Interpretation of results. 5.3.1. 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.
Interpretation of results. 6.3.1. The test for resistance to radiation shall be deemed to have given a positive result if the following conditions are fulfilled:
Interpretation of results. 2.4.1. The time t1 recorded for the least-favoured energy storage device shall not exceed:
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. 6.3.3.1. The cross-cut test shall be considered to have given a satisfactory result if:
Interpretation of results. The safety glazing shall be considered satisfactory with respect to abrasion resistance if the increase of haze as a result of abrasion of the test piece does not exceed 2 per cent.
Interpretation of results. 11.2.3.1. 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.
Interpretation of results. 5.3.1. Net power The net power declared by the manufacturer for the type of engine (or parent engine) shall be accepted if it does not differ by more than the values indicated in the table below, from the corrected values measured by the technical service on the engine submitted for testing. Engine Type Reference power [%] Other measurement points on the curve [%] Tolerance for engine speed [%] General ±2 ±4 ±1.5 Petrol fuelled spark ignited engines with governor ±4 ±6 ±4 Petrol fuelled spark ignited engines without governor ±4 ±10 ±4
