1.1 本术语汇编了聚合物材料（包括溶液、熔体和固体）动态机械性能测量中使用的技术术语的定义和说明。在其他现成来源中普遍理解或充分定义的术语要么不包括，要么确定来源。 1.2 定义是注释中包含附加信息的单个句子。每五年审查一次，并附上上次审查或修订的年份。 1.3 与其他标准组织或ASTM委员会发布的定义相同的定义用该组织或ASTM委员会名称的缩写标识。 1.4 动态机械测量专用术语的描述用斜体开头短语表示。 注1: 该术语标准类似于ISO 6721-1，但ISO文件引用的术语较少。 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 terminology is a compilation of definitions and descriptions of technical terms used in dynamic mechanical property measurements on polymeric materials, including solutions, melts, and solids. Terms that are generally understood or defined adequately in other readily available sources are either not included or sources identified. 1.2 A definition is a single sentence with additional information included in notes. It is reviewed every five years and the year of the last review or revision is appended. 1.3 Definitions identical to those published by another standards organization or ASTM committee are identified with the abbreviation of the name of the organization or the ASTM committee. 1.4 Descriptions of terms specific to dynamic mechanical measurements are identified with an italicized introductory phrase. Note 1: This terminology standard is similar to ISO 6721–1 however, the ISO document cites fewer terms. 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.
