GB/T 3681.2-2021 "Plastics solar radiation exposure test methods, Part 2: direct natural ageing and climate aging after exposure to window glass" specifies two plastic aging test methods: Method A is the exposure of plastics to direct solar radiation, Method B is the exposure of plastics to solar radiation after penetrating the window glass. The standard aims to evaluate the performance change of plastic materials under these conditions through exposure experiments with a set period. It is suitable for weathering resistance testing of various plastics and provides a scientific basis for the study of material durability.
