1.1 本指南列出了最终用户和红外热像仪在检查电气和机械系统时的责任。 1.2 本指南概述了记录电气和机械设备的定性和定量红外检查所需的具体内容。 2. 1.3 本指南可能涉及在存在加热、移动或所有这些或通电设备的情况下使用设备和材料。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 ====意义和用途====== 4.1 本指南可供最终用户用于指定电气和机械设备的红外检查以及执行这些检查的红外热像仪。 4.2 本指南列出了最终用户和红外热像仪在使用红外热像仪时的共同责任。 4.3 红外检查的目的是识别和记录最终用户的电气或机械系统中的异常情况，或两者兼而有之。 4.3.1 在电气设备中，热异常通常是由连接松动或退化、短路、过载、负载不平衡或部件故障、不匹配或安装不当引起的电阻增加引起的。冷却异常通常是由故障部件引起的。 4.3.2 在机械设备中，热异常通常是由润滑不当、错位、部件磨损或机械负载异常引起的摩擦造成的。冷却异常通常是由故障部件引起的。 4.3.3 绝缘系统的异常情况通常是由材料丢失或变质、安装不当或材料量不足引起的。 4.4 提供关于异常原因、设备完整性或纠正措施建议的意见，需要红外热像仪以外的知识和技能。 4.5 红外线检查仅在检查时提供有关设备的数据。 4.6 红外线检查不能补救。 4.7 对电气和机械设备进行红外线检查并不能保证其正常运行。 其他测试和适当的维护是确保其可靠性能所必需的。

1.1 This guide lists the responsibilities of the end user and the infrared thermographer when examining electrical and mechanical systems. 1.2 This guide outlines the specific content required to document qualitative and quantitative infrared examinations of electrical and mechanical equipment. 2 1.3 This guide may involve use of equipment and materials in the presence of heated, moving or all of these or electrically energized equipment. 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. ====== Significance And Use ====== 4.1 This guide can be used by an end user to specify infrared examinations of electrical and mechanical equipment and an infrared thermographer to perform them. 4.2 This guide lists the joint responsibilities of the end user and the infrared thermographer when using infrared thermography. 4.3 The purpose of an infrared examination is to identify and document exceptions in the end user's electrical or mechanical systems, or both. 4.3.1 In electrical equipment, warm exceptions are usually created by an increase in resistance caused by loose or deteriorated connections, short circuits, overloads, load imbalances or faulty, mismatched or improperly installed components. Cool exceptions are usually caused by failed components. 4.3.2 In mechanical equipment, warm exceptions are usually created by friction caused by improper lubrication, misalignment, worn components, or mechanical loading anomalies. Cool exceptions are usually caused by failed components. 4.3.3 Exceptions in insulation systems are usually caused by missing or deteriorated materials, improper installation, or insufficient amounts of material. 4.4 Providing opinions about the causes of exceptions, the integrity of the equipment, or recommendations for corrective actions require knowledge and skills beyond those of infrared thermography. 4.5 Infrared examinations provide data about equipment at the time of examination only. 4.6 Infrared examinations are not remedial. 4.7 An infrared examination of electrical and mechanical equipment does not assure its proper operation. Other tests and proper maintenance are necessary to ensure their reliable performance.
