The standard specifies the operating procedures for the Xenon-arc lamp device in exposure to non-metallic materials. The device is used to simulate the aging process of the material in both sunlight and moisture conditions to evaluate its performance in the actual use environment. The standard details the use of the Xenon-arc lamp and its Optical inspection Filter, as well as the basic operating procedures for exposing the sample to light, heat and moisture. To ensure Reliability of the results, it is recommended that control materials with known performance be used concurrently, and good laboratory practice followed to reduce variation. This standard does not address specific exposure condition settings, but provides guidance on operating the device and evaluation results.
