1.1 本规范涵盖铝1350-H19（超硬）、1350-H16或-H26( 3. / 4. 硬），1350-H14或-H24( 1. / 2. 硬）和1350-H142或-H242( 1. / 2. 硬）裸紧凑圆形同心绞合导线，由圆形或异形导线制成，用作非绝缘电导体或覆盖或绝缘电导体。这些导线应由一个中心芯组成，中心芯由一个或多个滚压或压模压实的螺旋线层包围（解释 注1 和 注2 )。 1.2 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 注1: 在1975年之前，铝1350被指定为EC铝。 注2: 铝和回火名称符合ANSI标准H35.1。铝1350对应于符合规程的统一编号系统A91350 E527 。 1.3 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 aluminum 1350-H19 (extra hard), 1350-H16 or -H26 ( 3 / 4 hard), 1350-H14 or -H24 ( 1 / 2 hard) and 1350-H142 or -H242 ( 1 / 2 hard) bare compact-round concentric-lay-stranded conductors made from round or shaped wires for use as uninsulated electrical conductors or in covered or insulated electrical conductors. These conductors shall be composed of a central core surrounded by one or more roller or die compacted layers of helically applied wires (Explanatory Note 1 and Note 2 ). 1.2 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. Note 1: Prior to 1975, aluminum 1350 was designated as EC aluminum. Note 2: The aluminum and temper designations conform to ANSI Standard H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527 . 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.
