标准摘要
[中文适用范围]： 本文件规定了两种方法：一种是塑料直接暴露于太阳辐射的方法（方法A），另一种是塑料暴露于经过玻璃过滤的太阳辐射（即暴露在窗玻璃后）的方法（方法B）。其目的是评估经过上述暴露阶段后材料性能的变化。关于ISO 877系列标准[1]的适用范围，可参考ISO 877-1。 [外文原描述]： This document specifies a method for the direct exposure of plastics to solar radiation (method A) and a method for the exposure of plastics to glass-filtered solar radiation (exposure behind window glass) (method B). The purpose is to assess property changes produced after specified stages of such exposures. General guidance concerning the scope of the ISO 877 series [ 1 ] is given in ISO 877-1.
