标准摘要
[中文适用范围]: 本文件规定了测定硬度范围为 30 IRHD 至 80 IRHD 的硫化橡胶的玻璃化转变温度 Tg 的方法。 动态特性是通过在定义的应变和频率下正弦变形中的温度扫描来测量的,Tg 由 tan δ 与温度曲线中的峰值确定。 以这种方式确定的玻璃化转变温度 Tg 可作为材料使用温度的指南。 [外文原描述]: This document specifies a method for determining the glass transition temperature, T g, of vulcanized rubbers in the hardness range from 30 IRHD to 80 IRHD. The dynamic properties are measured via temperature sweep in sinusoidal deformation at a defined strain and frequency and T g is determined from the peak in the tan δ versus temperature curve. Glass transition temperature, T g, determined in this way serves the purpose of a guideline to the service temperature of the material.
