10.2 Exposure apparatus
The exposure apparatus3) shall use a long arc xenon lamp as the source of irradiation, which shall comply with ISO 4892-2:2013, Method A (artificial weathering).
The long arc xenon lamp is advantageous in that it can, when correctly filtered and maintained, yield a spectrum most closely approximating that of natural sunlight. To this end, the quartz xenon burner tube shall be fitted with suitable borosilicate glass optical filter(s)4). The xenon lamps employed shall be operated from a suitable 50 Hz or 60 Hz power supply through suitable reactance transformers and electrical equipment.
The exposure apparatus shall include equipment necessary for measuring and/or controlling the following:
a) irradiance;
b) black standard temperature;
c) water spray;
d) operating schedule or cycle.
The exposure apparatus shall be made from inert materials which do not contaminate the water employed in the test.
Irradiance shall be measured at the test specimen surface and shall be controlled according to the recommendations of the exposure apparatus manufacturer.
Total ultraviolet5) radiance exposure, in joules per square metre, shall be measured or computed and shall be considered the primary measure of test specimen exposure.
10.3 Test specimens
The dimensions of the test specimens shall normally be those specified in the appropriate test method for the property or properties to be measured after exposure.
The number of test specimens for each test condition or exposure stage shall be determined, in addition to those required for visual evaluations as specified in 10.5 by the number required by the test methods.
It is recommended that visual evaluations be conducted on the largest test specimens tested.
10.4 Procedure
10.4.1 Measure, in accordance with iso 3538, the luminous transmission of the test specimen(s) to be exposed. Measure, in accordance with ISO 3537, the resistance to abrasion of the plastic surface(s) of the control specimen(s). That face of each test specimen which would represent the surface glazed to the exterior of the road vehicle shall face the lamp. Other exposure conditions shall be as specified in 10.4.2 to 10.4.11.
10.4.2 In accordance with ISO 4892-2, the irradiance shall not vary more than ±10 % over the whole test specimen area.
