The accelerated weathering tests are among the artificial forms of weathering. The destruction of the surface of plastics or coatings by filtered xenon arc irradiation together with cyclic deionized water spray is tested. This method, also known as "Sun Test", is used to determine weathering resistance of coating materials for exterior and (with the corresponding filters) interior usage.
It is tested according to e.g. VW PV 3929, VW PV 3930, SAE J2527, BMW AA-0235, ISO 2135, ISO 105-B02 and ISO 105-B06.
This test is part of the following manufacturer and requirement standards:
