1.1 本规范涵盖由圆铜线制成的裸束绞合导体，不论是未涂覆的还是涂覆有锡、铅或铅合金的，用作电导体（说明 附注1 和解释性的 附注2 ). 1.2 涂层导线应仅包括成品直径和密度基本上等于未涂层导线各自直径和密度的那些导线。 1.3 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中陈述的值可能不完全等同；因此，每个系统应独立使用。合并两个系统的值可能导致不符合标准。 1.3.1 对于由AWG或kcmil指定的导体尺寸，以SI单位表示的要求已由以英寸为单位的相应值进行数值转换-磅单位。对于仅由SI单位指定的导体尺寸，要求以SI单位陈述或推导。 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》中确立的国际公认的标准化原则制定的。

1.1 This specification covers bare bunch-stranded conductors made from round copper wires, either uncoated or coated with tin, lead, or lead-alloy for use as electrical conductors (Explanatory Note 1 and Explanatory Note 2 ). 1.2 Coated wires shall include only those wires with finished diameters and densities substantially equal to the respective diameters and densities of uncoated wires. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3.1 For conductor sizes designated by AWG or kcmil, the requirements in SI units have been numerically converted from corresponding values, stated or derived, in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units. 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.
