Scope: This document specifies the test method for the exposure of samples in the test equipment equipped with xenon arc lamp, heat and humidity. The test equipment simulates the actual use environment of total solar radiation or solar radiation through window glass, so that the material is Produces effects similar to natural aging. This document is applicable to laboratory artificial accelerated weathering tests of plastic specimens exposed to filtered xenon arc lamps under controlled environmental conditions (temperature, humidity and/or wetting). Different test requirements can be met by combining different types of xenon arc lamps and filters. Specimen preparation and result evaluation for specific materials refer to other standards. ISO 4892 1 gives the general principles of this document. Note: Refer to GB/T1865-2009 for the xenon arc lamp exposure test method for paints and varnishes.
