1.1 本术语汇编了ASTM文件中有关医疗器械用镍钛形状记忆合金的术语定义。该术语仅包括ASTM有标准或ASTM镍钛形状记忆合金标准中使用的术语。它不是与形状记忆合金相关的所有术语列表。 1.2 与其他标准机构发布的定义类似的定义用该组织名称的缩写标识；例如，ICTAC是国际热分析和量热联合会。 1.3 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 of terms used in ASTM documents relating to nickel-titanium shape memory alloys used for medical devices. This terminology includes only those terms for which ASTM either has standards or which are used in ASTM standards for nickel-titanium shape memory alloys. It is not intended to be an all-inclusive list of terms related to shape memory alloys. 1.2 Definitions that are similar to those published by another standards body are identified with abbreviations of the name of that organization; for example, ICTAC is the International Confederation for Thermal Analysis and Calorimetry. 1.3 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.
