前言:这是CAN/CSA-IEC 61000-4-4《电磁兼容性（EMC）-第4-4部分:测试和测量技术-电快速瞬变/脉冲群抗扰度测试》的第三版，它是在不修改同名IEC（国际电工委员会）标准61000-4-4（第三版，2012-04）的情况下采用的。它取代了2006年发布的前一版CAN/CSA-CEI/IEC 61000-4-4（采用IEC 61000-4-4:2004）。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。范围:IEC 61000的本部分涉及电气和电子设备对重复电气快速瞬变的抗扰度。它给出了与电快速瞬变/脉冲相关的抗扰度要求和测试程序。它还定义了测试级别的范围，并建立了测试程序。 本标准的目的是建立一个通用且可复制的参考，以评估电气和电子设备在电源、信号、控制和接地端口上遭受电快速瞬变/脉冲时的抗扰度。IEC 61000本部分中记录的试验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适用本抗扰度测试标准，如果适用，则负责确定适当的测试水平和性能标准。本标准定义:试验电压波形；测试水平的范围；测试设备；试验设备的校准和验证程序；测试设置；测试程序。本标准给出了实验室和现场试验的规范。

Preface:This is the third edition of CAN/CSA-IEC 61000-4-4,Electromagnetic compatibility (EMC) — Part 4-4: Testing and measurement techniques — Electrical fast transient/burst immunity test, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Standard 61000-4-4 (third edition, 2012-04). It supersedes the previous edition published in 2006 as CAN/CSA-CEI/IEC 61000-4-4 (adopted IEC 61000-4-4:2004).This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:This part of IEC 61000 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It gives immunity requirements and test procedures related to electrical fast transients/bursts. It additionally defines ranges of test levels and establishes test procedures.The object of this standard is to establish a common and reproducible reference in order to evaluate the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. 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.NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard is applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria.The standard defines:test voltage waveform;range of test levels;test equipment;calibration and verification procedures of test equipment;test setups;test procedure.The standard gives specifications for laboratory and in situ tests.
