1.1 本规范涵盖铝1350-O（退火）、1350-H12或-H22( 1. / 4. 硬），1350-H14或-H24( 1. / 2. 硬），1350-H16或-H26( 3. / 4. 硬）和1350-H142或-H242( 1. / 2. 硬），适用于绞合成导线或实心单导线，无论是裸导线还是绝缘导线（见 表1 或 表2 ). 1.2 以英寸-磅单位或国际单位表示的数值应单独视为标准值。每个系统中的值不是精确等价的；因此，每个系统应相互独立使用。合并两个系统的值可能会导致不符合规范。 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: 1975年之前，铝1350被指定为EC铝。 注2: 铝和回火名称符合ANSI H35.1。根据惯例，铝1350对应于统一编号系统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（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 1350-O (annealed), 1350-H12 or -H22 ( 1 / 4 hard), 1350-H14 or -H24 ( 1 / 2 hard), 1350-H16 or -H26 ( 3 / 4 hard) and 1350-H142 or -H242 ( 1 / 2 hard), suitable for stranding into conductors or for solid single conductors, either bare or insulated (see Table 1 or Table 2 ). 1.2 The values stated in inch-pound units or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 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 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.
