标准范围
本文件规定了测定硬度范围为30IRHD至80IRHD的硫化橡胶的玻璃化转变温度Tg的方法。动态特性通过在规定的应变和频率下正弦变形中的温度扫描来测量,并且Tg由tan δ对温度曲线中的峰值来确定。以这种方式测定的玻璃化转变温度Tg用于指导材料的使用温度的目的。
This document specifies a method for determining the glass transition temperature, Tg, 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 Tg is determined from the peak in the tan δ versus temperature curve. Glass transition temperature, Tg, determined in this way serves the purpose of a guideline to the service temperature of the material.
