电磁兼容性(EMC).第4-4部分:试验和测量技术.快速瞬变脉冲/脉冲串抗扰性试验

[中文适用范围]： 本部分IEC 61000标准涉及电气和电子设备对重复性电快速瞬变脉冲群的抗扰度。它给出了与电快速瞬变脉冲群相关的抗扰度要求和试验程序。此外，它还定义了试验电平范围并建立了试验程序。本标准的目的是建立一个共同且可重复的参考，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快速瞬变脉冲群作用时的抗扰度。本部分IEC 61000中记录的试验方法描述了一种评估设备或系统对定义现象抗扰度的一致方法。标准定义了：试验电压波形；试验电平范围；试验设备；试验设备的校准和验证程序；试验布置；试验程序。该标准给出了实验室试验和现场试验的规格。 [外文原描述]： 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.
