The ASTM D6695-16 standard guide applies to Xenon-arc exposure testing for Coatings and related Coatings. It provides 7 different Xenon-arc exposure cycles to simulate changes in the performance of coatings under environmental factors such as light, heat, and moisture. These cycles include General Coatings, External Pigment Stains, Automotive Appearance, and more. These cycles are designed to simulate different outdoor environmental conditions through Xenon-arc Light sources and evaluate the durability and performance of coatings. The standard guides users to select the appropriate test cycle for a specific application and to measure the mechanical and aesthetic performance of coatings after testing.
