意义及用途
4.1 Rubber and rubber products need to resist the deterioration of physical properties over time caused by oxidation and thermal aging. The test method provides a way to evaluate these performance characteristics of rubber under certain acceleration conditions specified.
4.2 For important information on standard compounds used for precision testing to accelerate test aging assessment, see Annex A1.

1.1 This test method covers procedures for determining the effect of high temperature on the physical properties of vulcanized rubber. Because performance conditions vary widely, the results of this test method may not fully correlate with service performance. 然而, the test method can be used to evaluate rubber compounds on the basis of laboratory comparisons.
1.2 以 SI 单位表示的值应被视为标准值. 括号内的数值仅供参考.
1.3 本标准并非旨在解决所有安全问题, 如果有的话, 与其使用相关. 本标准的使用者有责任建立适当的安全机制, 健康和环境实践，并在使用前确定监管限制的适用性. See Note 1 for specific precautions.
1.4 本国际标准基于《关于制定国际标准的原则的决定》中确立的国际公认的标准化原则, Guidelines and Recommendations issued by the WTO Committee on Technical Barriers to Trade.
