1.1 本规范涵盖了电力设施和相关行业在电压高于1 kV的带电线路上使用的未使用绳索的要求、尺寸、施工、测试和程序。 1.2 本规范涵盖制造商保证的最低电气、机械和物理性能，以及确定此类性能的详细程序。买方可以选择执行或已经执行任何这些测试，以验证担保。不符合规范的索赔应由制造商进行验证。 1.3 本规范适用的绳索设计用于清洁干燥的条件下，在通电线路上或附近使用。 1.4 最大电压和工作距离与测试电压和测试长度之间应留有安全余量。 1.5 这类设备的用户通常会编制完整的说明和规定，以详细管理此类设备的正确和安全使用。 1.6 本设备的使用和维护不在本规范范围内。 1.7 以国际单位制表示的数值应视为标准。 1.8 以下安全隐患警告仅适用于试验方法部分第节 11 ，本规范: 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。 本标准中使用的测试水平用于实验室条件下的测试，不被视为安全使用水平。 1.9 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 the requirements, sizes, construction, tests, and procedures for unused ropes for use by electrical utilities and related industries on energized lines operating at voltages higher than 1 kV. 1.2 This specification covers the minimum electrical, mechanical, and physical properties guaranteed by the manufacturer and the detailed procedures by which such properties are to be determined. The purchaser has the option to perform or have performed any of these tests in order to verify the guarantee. Claims for failure to meet the specification are subject to verification by the manufacturer. 1.3 The rope to which this specification applies is designed to be used in a clean and dry condition, on or near energized lines. 1.4 A margin of safety shall be allowed between the maximum voltage and working distances on which it is used and the test voltage and lengths at which it is tested. 1.5 It is common practice for the user of this type of equipment to prepare complete instructions and regulations to govern in detail the correct and safe use of such equipment. 1.6 The use and maintenance of this equipment is beyond the scope of this specification. 1.7 The values stated in SI units are to be regarded as the standard. 1.8 The following safety hazards caveat pertains only to the test method portion, Section 11 , of this specification: 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. The test levels used in this standard are for testing under laboratory conditions and are not to be regarded as safe use levels. 1.9 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.
