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）裸同心绞合导线，由一层或多层螺旋层导线围绕的直圆形中心导线构成。导线一般用于电气目的（说明 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。 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。 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/H35.1M。根据惯例，铝1350对应于统一编号系统A91350 E527 。 注3: 本规范指南中也允许使用旨在防止水纵向传播并进一步覆盖/绝缘的密封导体。 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 concentric-lay-stranded conductors constructed with a straight round central wire surrounded by one or more layers of helically layed wires. The conductors are for general use for electrical purposes (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. 1.2.1 For density, resistivity and temperature, the values stated in SI units are to be regarded as 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/H35.1M. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527 . Note 3: Sealed conductors that are intended to prevent longitudinal water propagation and are further covered/insulated are also permitted within the guidelines of this specification. 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.
