The ASTM D4459-2021 standard describes the xenon arc exposure test method for indoor plastics. The standard simulates the aging process of plastics under indoor lighting conditions by using a Xenon-arc device fitted with a window glass Filter. Standard practices G151 and G155 are to be followed for testing operations to ensure the accuracy of the results. Special attention should be paid to the status of operating equipment, such as voltage, temperature, and Humidity control, as well as the maintenance of lamps and filters during testing. The standard recommends testing control materials with known performance at the same time, and performing multiple repeability tests to ensure the Reliability of the results. This standard does not cover all safety issues related to use, and users need to take appropriate safety measures according to the actual situation.
