Summary
ASTM D5208 is a standardized practice used to evaluate the photodegradability of plastics and similar nonmetallic materials. It simulates the effects of sunlight, heat, and moisture by exposing samples to fluorescent UV light under controlled laboratory conditions. This analysis is primarily aimed at assessing how rapidly materials lose their chemical, physical, or mechanical properties after use when exposed to typical outdoor environments.
ASTM D5208 Testing Method
In this test, samples are exposed to fluorescent UV lamps in a weathering chamber. The samples are periodically extracted at designated intervals and select properties are measured against a control sample to determine the material’s susceptibility to photodegradation. The exposure conditions (UV intensity, temperature, duration, and humidity/cooling cycles) must be defined and controlled closely throughout the test intervals.
It’s best practice to assess the sample’s properties directly after each testing interval as their properties can continue changing post-exposure. This method is suitable for photodegradable plastics and can also be used for insulating materials (up to 20mm thick).
