The ASTM D5071-2006 standard test method is used to evaluate the durability of photodegradation plastics exposed in xenon arc devices. This method simulates the photodegradation process of plastics in an environment of solar radiation, oxygen, heat and moisture, but does not include the effects of local weather phenomena. The test accelerates the degradation process of materials by controlling temperature and Humidity and does not directly reflect the absolute degradation rate in the actual environment. Reliability of test results depends on the operation and maintenance of the equipment. It is recommended to use control materials with known performance for comparison to improve test conformity. This standard applies to specific test procedures and conditions for photodegradation plastics.
