新的！IEC 61000-4-4:20 12作为IEC标准+61000-4-4:20 12提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。 IEC 61000-4-4:20 12涉及电气和电子设备对重复电气快速瞬变的抗扰度。根据IEC指南107，它具有基本EMC出版物的地位。它给出了与电气快速瞬变/突发相关的抗扰度要求和测试程序。它还定义了测试水平的范围并建立了测试程序。本标准的目的是建立一个通用的和可重复的参考，以评估电气和电子设备在电源、信号、控制和接地端口受到电气快速瞬变/突发时的抗扰度。本标准中记录的试验方法描述了评估设备或系统对规定现象的抗扰度的一致方法。本第三版取消并取代了2004年出版的第二版及其修正案1(2010)。它构成了一个技术修订，改进和澄清了模拟器规范、测试标准和测试设置。

NEW! IEC 61000-4-4:2012 is available as IEC Standards+ 61000-4-4:2012 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61000-4-4:2012 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It has the status of a basic EMC publication in accordance with IEC Guide 107. 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 standard describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. This third edition cancels and replaces the second edition published in 2004 and its amendment 1 (2010). It constitutes a technical revision which improves and clarifies simulator specifications, test criteria and test setups.
