标准摘要
[中文适用范围]: 本文件规定了一种使用热膨胀法[1]的测试方法,通过热机械分析(TMA)测定固态塑料的线性热膨胀系数。 本文件还规定了使用 TMA 测定玻璃化转变温度。 注:线性热膨胀系数可以使用各种类型的热膨胀仪来测量。 本文件仅涉及 TMA 设备。 [外文原描述]: This document specifies a test method, using thermodilatometry [1] , for the determination of the coefficient of linear thermal expansion of plastics in a solid state by thermomechanical analysis (TMA). This document also specifies the determination of the glass transition temperature using TMA. NOTE The coefficient of linear thermal expansion can be measured using various types of thermodilatometry apparatus. This document concerns only TMA apparatus.
