Application Summary AI generated

This standard specifies test methods for evaluating the resistance of anodic oxidation coatings and organic polymer coatings on aluminium and aluminium alloys to combined ultraviolet (UV) light and heat exposure. It is applied in manufacturing and quality control for products such as architectural panels, automotive trim, and consumer electronics, where coatings must withstand outdoor weathering or indoor UV-rich environments. The testing simulates accelerated aging to assess coating degradation, including discoloration, gloss loss, or delamination.
