标准范围

本文件提供了一种在室外风化和室内加速风化试验期间评估聚合物早期氧化降解状态的方法，还可以评估各种添加剂的影响。该方法基于一种分析方法，其中通过测量化学诱导的超微弱光子发射（UPE）敏感地检测聚合物氧化降解反应的进展程度。

This document provides a method for assessing the very early oxidative degradation state of polymers during outdoor weathering and indoor accelerated weathering tests and the influence of various additives can also be evaluated.This method is based on an analytical method in which the degree of progress of the oxidative degradation reaction of a polymer is sensitively detected by measurement of chemically induced ultra-weak photon emission (UPE).
