美国阿特拉斯户外紫外加速试验系统跟踪研究

摘要

The structure composition and function of Atlas’s UV-accelerated weathering system were analyzed in detail in this paper. At the same time, by comparing the UV radiant exposure of the sample on the ultra-accelerated device in a single year exposure with that in a SAE J2527 xenon arc exposure in 45° South Florida measured using the ASTM G90 standard me-thod, the acceleration and correlation of the system were described.%详细剖析了美国阿特拉斯研发的紫外加速试验系统（UAWS）的结构构成和功能，同时通过该系统样品暴露1年接受的紫外辐射量与佛罗里达州南45°、使用SAE J2527氙弧暴露、ASTM G90标准方法之间的量值比较，对该系统的加速性和相关性进行了阐述。
