1.1 本规范涵盖架空铝导线的非镜面表面处理。架空铝导线在安装时通常具有光亮的表面外观。这种“反射”或“镜面反射”表面可以使传输线在背景景观中的外观更明显。铝线外表面的工厂处理过程可以使表面光洁度变暗、不反光、哑光灰色。这种非反射或“去眩光”表面光洁度使导体在远距离观察时变得不可见，并使输电线路与天际线或景观背景融合。 2. 1.2 本规范旨在通过漫反射测量建立用户可接受的导体表面均匀性。该规范将为一致的制造过程控制提供基础。 1.3 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。 1.4 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。 1.5 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 non-specular surface finishes on overhead aluminum electrical conductors. Overhead aluminum electrical conductors, when installed, typically have a shiny surface appearance. This “reflective” or “specular” surface can make a transmission line more noticeable in appearance against the background landscape. A factory treatment process of the outer surface of the aluminum wires can render the surface finish into a dull, non-reflective, matte grey finish. This non-reflective or “de-glared” surface finish allows the conductor to become less visible when observed from a distance and enables the transmission line to blend in with the skyline or landscape background. 2 1.2 This specification is intended, by means of diffuse reflectance measurement, to establish a uniformity of conductor finish which is acceptable to the user. Such a specification will furnish a basis for consistent manufacturing process control. 1.3 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. 1.4 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. 1.5 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.
