1.1 本试验方法涵盖了通过质量法测定拟用于电子应用的非绝缘绞合导线抗拉强度的程序（解释性 注1 ). 1.1.1 本试验方法适用于一种类型的导线（非复合导线）。普通、包层或涂层的导线类型，并绞合在一起，以作为单导线进行机械和电气操作。 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。第7节“危险”中给出了一些具体的危险说明。 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。 ====意义和用途====== 4.1 本试验方法旨在检查或验收绞合金属导线的抗拉强度。

1.1 This test method covers the procedure for determining the tensile strength by a mass method for uninsulated stranded electrical conductors intended for use in electronic application (Explanatory Note 1 ). 1.1.1 The test method is intended for conductors that are one type of wire (non-composite). The wire type being plain, clad, or coated and stranded together to operate mechanically and electrically as a single conductor. 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 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. Some specific hazards statements are given in Section 7 on Hazards. 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. ====== Significance And Use ====== 4.1 This test method is designed as an inspection or acceptance test of tensile strength for stranded metallic conductors.
