Accelerated weathering tests are a form of artificial weathering. In these tests, the degradation of the surface of plastics or coatings is assessed using filtered xenon arc radiation in combination with cyclic spraying with deionised water. This method, also known as a ‘sun test’, is used to determine the weather resistance of coating materials for external use and (with the appropriate filters) for internal use.
