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），1350-H142或-H242( 1. / 2. 硬质）和铝合金8XXX系列，如规范所列 B800型 对于回火“O”和H1X或H2X，裸绞合导线由一个或多个辊形或模具压缩的螺旋层导线组成。导线一般用于电气目的（解释性 注释1和 2. ). 注1: 就本规范而言，单输入线（SIW）结构定义如下:一种绞合导线设计方法，在导线尺寸范围内改变导线数量，以允许该导线尺寸范围由单线尺寸构成。 1.2 电阻率的SI值被视为标准值。对于所有其他属性，英寸-磅单位被视为标准单位，国际单位制可能是近似单位。 注2: 1975年之前，铝1350被指定为EC铝。 注3: 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 . 8000系列的铝合金符合统一编号系统A98XXX的要求 E527 . 注4: 本规范还允许导线用作覆盖或绝缘导线。 注5: 本规范指南中也允许使用旨在防止纵向水传播并进一步覆盖/绝缘的密封导线。 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-H19 (extra hard), 1350-H16 or -H26 ( 3 / 4 hard), 1350-H14 or -H24 ( 1 / 2 hard), 1350-H142 or -H242 ( 1 / 2 hard), and aluminum alloy 8XXX series as listed in Specification B800 for tempers “O” and H1X or H2X, bare stranded conductors composed of one or more roller shaped or die compressed layers of helically layed wires. The conductors are for general use for electrical purposes (Explanatory Notes 1 and 2 ). Note 1: For the purposes of this specification, single input wire (SIW) construction is defined as follows: a stranded conductor design methodology that varies the number of wires within a range of conductor sizes in order to permit that range of conductor sizes to be constructed from a single wire size. 1.2 The SI values for resistivity are regarded as standard. For all other properties, the inch-pound units are regarded as standard and the SI units may be approximate. Note 2: Prior to 1975, aluminum 1350 was designated as EC aluminum. Note 3: The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527 . Aluminum alloys in the 8000 series correspond to Unified Numbering System A98XXX in accordance with Practice E527 . Note 4: This specification also permits conductors for use as covered or insulated electrical conductors. Note 5: Sealed conductors, which 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.
