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 1.3 本指南可能涉及在存在加热、移动或所有这些设备或通电设备的情况下使用设备和材料。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 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，并可由红外热像仪执行这些检查。 本指南列出了最终用户和红外热成像仪在使用红外热成像时的共同责任。 红外检测的目的是识别并记录最终用户电气或机械系统中的异常情况，或两者。 4.3.1在电气设备中，温异常通常由连接松动或劣化、短路、过载、负载不平衡或故障、不匹配或安装不当的部件引起的电阻增加引起。 冷异常通常由故障组件引起。 4.3.2在机械设备中，温异常通常由润滑不当、错位、磨损部件或机械负载异常引起的摩擦引起。冷异常通常由故障组件引起。 4.3.3绝缘系统中的例外情况通常由材料缺失或变质、安装不当或材料数量不足引起。 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成像以外的知识和技能。 红外线检查仅提供检查时的设备数据。 红外线检查不是补救措施。 对电气和机械设备进行红外检测不能确保其正常运行。其他测试和适当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 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 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. This guide lists the joint responsibilities of the end user and the infrared thermographer when using infrared thermography. The purpose of an infrared examination is to identify and document exceptions in the end user’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. 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. Infrared examinations provide data about equipment at the time of examination only. Infrared examinations are not remedial. 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.
