ActivePlastics—Methods of exposure to solar radiation—Part 2: Direct weathering and exposure behind window glass
塑料 太阳辐射暴露试验方法 第2部分：直接自然气候老化和暴露在窗玻璃后气候老化
Application Summary AI generated
This standard specifies procedures for exposing plastic specimens to natural solar radiation, either directly or behind window glass, to assess weathering effects. It is applied in the plastics industry for testing the durability and colorfastness of materials used in outdoor products like automotive parts, building components, and window films. The standard is also used in quality control and research to simulate real-world aging conditions for plastics exposed to sunlight through glass.
