标准摘要
[中文适用范围]： IEC 61000的这一部分涉及电气和电子设备在运行条件下对公共和非公共网络提供的低压电源、控制和信号线路中出现的振铃波的抗扰度要求和测试方法。本文件的目的是建立一个通用参考，用于评估电气和电子设备在受到环波时的抗扰度。 IEC 61000 本部分中记录的测试方法描述了评估设备或系统对特定现象的抗扰度的一致方法。注：如 IEC 指南 107 中所述，这是供 IEC 产品委员会使用的基本 EMC 出版物。正如指南 107 中所述，IEC 产品委员会负责确定是否应用该抗扰度测试标准，如果应用，他们负责确定适当的测试级别和性能标准。 TC 77 及其小组委员会准备与产品委员会合作评估其产品的特定抗扰度测试和测试水平的价值。本文件定义：测试电压和电流波形；一系列测试级别；测验设备;测试设置；测试程序。 [外文原描述]： IEC 61000-4-12:2017 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to ring waves occurring in low-voltage power, control and signal lines supplied by public and non-public networks. The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to ring waves. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. It has the status of a basic EMC publication in accordance with IEC Guide 107. This edition includes the following significant technical changes with respect to the previous edition: a) addition of a mathematical modelling of ring wave waveform; b) new Annex B on selection of generators and test levels; c) new Annex C on explanatory notes; d) new Annex D on measurement uncertainty; e) addition of high speed CDN; f) addition of a calibration procedure for CDN.
