1.1 本规程涵盖了根据聚合物链的化学成分确定的干型和乳胶型基本橡胶的一般分类系统。 1.2 本惯例的目的是为工业、商业和政府中使用的术语提供标准化，其目的不是与现有商号和商标冲突，而是作为对现有商号和商标的补充。 1.3 在技术论文或演示文稿中，如有可能，应使用聚合物的名称。这些符号可以跟在化学名称后面，以便在以后的参考文献中使用。 注1: 有关热塑性弹性体的术语，请参阅规程 D5538 . 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。

1.1 This practice covers a system of general classification for the basic rubbers both in dry and latex forms determined from the chemical composition of the polymer chain. 1.2 The purpose of this practice is to provide a standardization of terms for use in industry, commerce, and government and is not intended to conflict with but rather to act as a supplement to existing trade names and trademarks. 1.3 In technical papers or presentations the name of the polymer should be used if possible. The symbols can follow the chemical name for use in later references. Note 1: For terms related to thermoplastic elastomers, see Practice D5538 . 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.
