ActivePlastics—Methods of exposure to laboratory light sources—Part 3: Fluorescent UV lamps
塑料 实验室光源暴露试验方法 第3部分：荧光紫外灯
Application Summary AI generated
This standard specifies the test method for exposing plastics to fluorescent UV lamps in a laboratory setting to simulate the damaging effects of sunlight, particularly the UV spectrum. It is applied in the plastics industry for accelerated weathering tests to evaluate material degradation, such as color change, gloss loss, or mechanical property reduction. Manufacturers and quality control labs use it to predict the long-term outdoor durability of plastic products, including automotive parts, building materials, and packaging.
