1.1 本规范涵盖了电气工人使用的结构安装绝缘工作平台的机械和电气特性的设计测试。 1.2 本规范涵盖的平台是长度不超过9英尺（2.75米）的单人平台。设计为一次支持多个工人的平台超出了本规范的范围。 1.3 非绝缘平台不在本规范的范围内。 1.4 本设备的使用和维护超出了本规范的范围。 1.5 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 1.6 以下安全危害警告仅适用于试验方法部分，章节 9 本规范: 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.7 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》中确立的国际公认的标准化原则制定的。

1.1 This specification covers the design testing of mechanical and electrical characteristics of structure-mounted insulating work platforms used by electrical workers. 1.2 Platforms covered by this specification are singleworker platforms not exceeding 9 ft (2.75 m) in length. Platforms designed to support more than one worker at a time are beyond the scope of this specification. 1.3 Non-insulating platforms are not within the scope of this specification. 1.4 The use and maintenance of this equipment are beyond the scope of this specification. 1.5 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. 1.6 The following safety hazards caveat pertains only to the test method portion, Section 9 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. 1.7 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.
