标准编号：ISO 2921:2011
中文名称：硫化橡胶 低温收缩性的测定（TR试验）
英文名称：Rubber, vulcanized — Determination of low-temperature retraction (TR test)
发布日期：2011-10
标准范围
This International Standard specifies a method for the determination of the temperature-retraction characteristics of stretched vulcanized rubber.This International Standard does not cover thermoplastic rubbers, as many thermoplastic elastomers have a yield point in the range of 5 % to 20 % elongation. This fact might affect the result when carrying out TR tests on thermoplastic rubbers, and the results obtained from such tests should be analysed with caution.
