1.1 本规范涵盖由圆形或异型导线制成的铝/单输入线（SIW）绞合导线，用于有盖或绝缘电线或电缆。这些导线应由一个或多个滚压或模压的螺旋应用导线层组成（说明 注1 解释性的 注释2 ，并进行解释 附注3 ). 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。 1.2.1 对于密度、电阻率和温度，以国际单位制表示的值应视为标准值。 注1: 铝和回火名称符合ANSI H35.1。根据惯例，铝1350和铝合金8XXX对应于统一编号系统A91350和A98XXX E527 . 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 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》中确立的国际公认标准化原则制定的。

1.1 This specification covers aluminum/single input wire (SIW) stranded conductors made from round or shaped wires for use in covered or insulated electrical wires or cables. These conductors shall be composed of one or more roller or die compacted layers of helically applied wires (Explanatory Note 1 , Explanatory Note 2 , and Explanatory Note 3 ). 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. 1.2.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard. Note 1: The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 and Aluminum-Alloy 8XXX correspond to Unified Numbering System A91350 and A98XXX, in accordance with Practice E527 . 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.
