标准编号：ISO 2921:2019

中文名称：硫化橡胶 低温收缩性的测定 温度-回缩程序（TR测试）

英文名称：Rubber, vulcanized — Determination of low-temperature characteristics — Temperature-retraction procedure (TR test)

发布日期：2019-10

标准范围

This document specifies a method for the determination of the temperature-retraction characteristics 
of stretched vulcanized rubber.
This document does not cover thermoplastic rubbers, as many thermoplastic elastomers have a yield 
point in the range of 5 % to 20 % elongation.
