标准摘要
[中文适用范围]： 本文件规定了使用热重技术分析聚合物的一般条件。 它适用于液体或固体。 固体材料可以是丸粒、颗粒或粉末的形式。 减小到适当样本尺寸的制造形状也可以通过该方法进行分析。 本文件建立了研究与质量变化相关的物理效应和化学反应的方法。 该文件可用于确定聚合物分解的温度和速率，并同时测量它们所含的挥发性物质、添加剂和/或填料的量。 本文件适用于动态模式（在编程温度条件下质量变化随温度或时间变化）或等温模式（在恒温下质量变化随时间变化）的测量。 本文件适用于不同测试气氛下的测量，例如惰性气氛中的分解与氧化降解的分离。 [外文原描述]： This document specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids or solids. Solid materials can be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size can also be analysed by this method. This document establishes methods for the investigation of physical effects and chemical reactions that are associated with changes of mass. This document can be used to determine the temperature(s) and rate(s) of decomposition of polymers, and to measure at the same time the amounts of volatile matter, additives and/or fillers they contain. This document is applicable to measurements in dynamic mode (mass change versus temperature or time under programmed temperature conditions) or isothermal mode (mass change versus time at constant temperature). This document is applicable to measurements at different testing atmospheres, such as separation of decomposition in an inert atmosphere from oxidative degradation.
