1.1 本试验方法涵盖了确定高温对硫化橡胶物理性能影响的程序。由于性能条件差异很大，因此该测试方法的结果可能与使用性能没有精确的相关性。然而，本试验方法可用于在实验室比较的基础上评估橡胶化合物。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 （有关具体预防说明，请参阅 注1 .) 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 橡胶和橡胶制品必须能够抵抗氧化和热老化引起的物理性能随时间的恶化。本试验方法提供了一种在规定的某些加速条件下评估橡胶性能特征的方法。 4.2 请参阅 附件A1 有关用于加速试验老化评估精密试验的标准化合物的重要信息。

1.1 This test method covers a procedure to determine the influence of elevated temperature on the physical properties of vulcanized rubber. The results of this test method may not give an exact correlation with service performance since performance conditions vary widely. This test method may, however, be used to evaluate rubber compounds on a laboratory comparison basis. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (For specific precautionary statement, see Note 1 .) 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Rubber and rubber products must resist the deterioration of physical properties with time caused by oxidative and thermal aging. This test method provides a way to assess these performance characteristics of rubber, under certain accelerated conditions as specified. 4.2 Please refer to Annex A1 for important information on standard compounds used for precision testing for accelerated test aging evaluation.
