1.1 本规范涵盖以下应用的裸圆形覆铜钢:电气、电子、接地、电信和其他应用。 1.2 四种电导率如下:21 %, 30 %, 40 %, 和70 %. 1.3 回火被指定为退火。 1.4 以英寸磅或国际单位制表示的数值应单独视为标准。每个系统应独立使用。将两个系统的值组合在一起可能会导致不符合规范。对于AWG指定的导线尺寸，以国际单位表示的要求已从以英寸表示或导出的相应值进行了数字转换- 磅单位。对于仅用国际单位制指定的导线尺寸，要求以国际单位制表示或推导。 1.5 以下预防声明仅适用于第节中的试验方法部分 7. ，本规范: 本标准并非旨在解决所有与使用相关的安全问题（如有）。本标准的使用者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。 1.6 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 This specification covers bare round copper-clad steel for the following applications: electrical, electronic, grounding, telecommunications, and other applications. 1.2 Four conductivities are covered as follows: 21 %, 30 %, 40 %, and 70 %. 1.3 Temper is designated as annealed. 1.4 The values stated in inch-pound or SI units are to be regarded separately as the standard. Each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. For conductor sizes designated by AWG, 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. 1.5 The following precautionary statement pertains to the test method portion only, Section 7 , of this specification: 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. 1.6 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.
