The standard specifies an aging test method for Non-metallic materials under simulated sun and water exposure conditions. This procedure uses fluorescent ultraviolet (UV) and condensation devices to simulate the deteriorating effects of sun radiation and moisture on materials. The standard covers the basic principles and operating procedures for acquiring, measuring and controlling these exposure conditions, but does not address the exposure conditions for specific materials or the preparation and evaluation of results of specimens. These should refer to the corresponding ASTM test method or material specification. The standard expresses values in SI units and requires users to establish appropriate safety and health practices prior to use.
