1.1 本分类体系涵盖了硫化橡胶材料（天然橡胶、再生橡胶、合成橡胶，单独或组合）的性能，这些材料用于但不限于汽车用橡胶产品。 注1: 该分类系统可以以与SAE编号的钢材大致相同的方式满足其他行业的许多需求。然而，必须记住，当汽车需要时，该系统可能会进行修订。建议始终使用最新版本。 1.2 该分类系统的前提是，所有橡胶产品的性能可以安排为特征材料名称。这些名称由 类型 ，基于耐热老化，以及 课程 ，基于在油中的抗溶胀性。 因此，建立了基本水平，与描述附加要求的值一起，允许完整描述所有弹性材料的质量。 1.3 在所有情况下，如果该分类系统的规定与特定产品的详细规范的规定相冲突，则应以后者为准。 注2: 当橡胶产品用于本分类系统无法完全规定要求的特定用途时，买方有必要提前咨询供应商，以确定适当的性能、测试方法和规格测试限值。 1.4 以国际单位制表示的数值应视为标准值。 1.5 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。

1.1 This classification system covers the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. Note 1: This classification system may serve many of the needs of other industries in much the same manner as SAE numbered steels. It must be remembered, however, that this system is subject to revision when required by automotive needs. It is recommended that the latest revision always be used. 1.2 This classification system is based on the premise that the properties of all rubber products can be arranged into characteristic material designations. These designations are determined by types , based on resistance to heat aging, and classes , based on resistance to swelling in oil. Basic levels are thus established which, together with values describing additional requirements, permit complete description of the quality of all elastomeric materials. 1.3 In all cases where the provisions of this classification system would conflict with those of the detailed specifications for a particular product, the latter shall take precedence. Note 2: When the rubber product is to be used for purposes where the requirements are too specific to be completely prescribed by this classification system, it is necessary for the purchaser to consult the supplier in advance, to establish the appropriate properties, test methods, and specification test limits. 1.4 The values stated in SI units are to be regarded as standard. 1.5 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.
