标准摘要
[中文适用范围]： IEC 61000的该部分涉及与开关和雷电瞬变引起的过电压有关的单向浪涌的抗扰度要求、测试方法和建议的测试等级范围。定义了若干测试等级，涉及不同的环境和安装条件。这些要求是为电气和电子设备开发并适用于它们的。本标准旨在为评估电气和电子设备在遭受浪涌时的抗扰度建立一个共同参考。IEC 61000的该部分记录的测试方法描述了评估设备或系统对定义现象的抗扰度的一致性方法。注：如IEC指南107所述，这是IEC产品委员会使用的基本EMC出版物。如指南107所述，IEC产品委员会负责确定是否应用此抗扰度测试标准，如果应用，则负责确定适当的测试等级和性能标准。TC 77及其分委员会准备与产品委员会合作评估特定抗扰度测试等级对其产品的价值。本标准定义了：测试等级范围；测试设备；测试设置；测试程序。所描述的实验室测试的任务是确定被试设备（EUT）在规定的操作条件下对开关和雷电效应引起的浪涌电压的反应。本标准的意图不是测试EUT的绝缘承受高压应力的能力。不考虑雷电电流的直接注入，即直接雷击。 [外文原描述]： IEC 61000-4-5:2014+A1:2017 relates to the immunity requirements, test methods, and range of recommended test levels for equipment with regard to unidirectional surges caused by over-voltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. This standard defines a range of: - test levels; - test equipment; - test setups; and - test procedures. The task of the described laboratory test is to find the reaction of the equipment under test (EUT) under specified operational conditions to surge voltages caused by switching and lightning effects. It is not intended to test the capability of the EUT's insulation to withstand high-voltage stress. Direct injections of lightning currents, i.e. direct lightning strikes, are not considered in this standard. This third edition cancels and replaces the second edition published in 2005, and constitutes a technical revision which includes the following significant technical changes with respect to the previous edition: - a new Annex E on mathematical modelling of surge waveforms; - a new Annex F on measurement uncertainty; - a new Annex G on method of calibration of impulse measuring systems; and - a new Annex H on coupling/decoupling surges to lines rated above 200 A. Moreover while surge test for ports connected to outside telecommunication lines was addressed in 6.2 of the second edition (IEC 61000-4-5:2005), in this third edition (IEC 61000-4-5:2014) the normative Annex A is fully dedicated to this topic. In particular it gives the specifications of the 10/700 µs combined wave generator. This consolidated version consists of the third edition (2014) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.
