IEC 61000-4-25:2001+A1:2012描述了暴露于高空电磁脉冲（HEMP）环境的电气和电子设备和系统的抗扰度测试水平和相关测试方法。本标准还定义了测试设备和仪器测试设置、测试程序、通过/失败标准和测试文件要求的规范。这些测试旨在证明电气和电子设备在受到大麻辐射和传导电磁干扰时的抗扰度。IEC 61000这一部分的目的是建立一个通用且可重复的基础，用于评估电气和电子设备在受到HEMP辐射环境以及电源、天线、输入/输出（I/O）信号和控制线上的相关传导瞬变时的性能。修正案1引入了最近发布的阻尼正弦波标准IEC 61000-4-18。 本合并版本由第一版（2001年）组成 及其修正案1（2012）。因此，无须在 本出版物的补充。

IEC 61000-4-25:2001+A1:2012 describe immunity test levels and related test methods for electrical and electronic equipment and systems exposed to high-altitude electromagnetic pulse (HEMP) environments. Specifications for test equipment and instrumentation test set-up, test procedures, pass/fail criteria, and test documentation requirements are also defined by this standard. These tests are intended to demonstrate the immunity of electrical and electronic equipment when subjected to HEMP radiated and conducted electromagnetic disturbances. The objective of this part of IEC 61000 is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment, when subjected to HEMP radiated environments and the associated conducted transients on power, antenna, and input/output (I/O) signal and control lines. The amendment 1 introduces the damped sinusoidal wave standard recently published IEC 61000-4-18. This consolidated version consists of the first edition (2001) and its amendment 1 (2012). Therefore, no need to order amendment in addition to this publication.
