1.1 本规范涵盖尺寸为0.2043至0.0808英寸的一般电气用途的裸、硬拉、圆形铝包钢线的四种电导率。包括（4到12 AWG）( 注1 ). 本规范不适用于ACSR导线中用作钢筋的导线。（见规范 B502型 .) 注1: 根据本规范订购的电线不用于重新绘制。如果需要使用电线，应咨询制造商。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 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 specification covers four conductivities of bare, hard-drawn, round, aluminum-clad steel wire for general use for electrical purposes in sizes 0.2043 to 0.0808 in. incl (4 to 12 AWG) ( Note 1 ). This specification does not apply to wires used as reinforcement in ACSR conductors. (See Specification B502 .) Note 1: Wire ordered to this specification is not intended for redrawing. If wire is desired for this purpose, the manufacturer shall be consulted. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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.
