1.1 这些定义涵盖了通用术语，包括商业重要性术语，这些术语出现在一个或多个关于含有高模量（大于20 GPa（3 × 10 6. psi））纤维。 1.2 在大多数情况下，这些定义涵盖了复合材料行业中使用的特殊含义。没有人试图将复合材料行业外使用的相同术语的共同含义包括在内。 1.3 一般来说，所包含的定义已被批准为标准。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 These definitions cover generic terms, including terms of commercial importance, that appear in one or more standards on composites containing high-modulus (greater than 20 GPa (3 × 10 6 psi)) fibers. 1.2 The definitions cover, in most cases, special meanings used in the composites industry. No attempt has been made to include common meanings of the same terms as used outside the composites industry. 1.3 Definitions included have, in general, been approved as standard. 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.
