IEC 61000-4-27:2000+A1:2009考虑了电气和/或电子设备（仪器和系统）在其电磁环境中的抗扰度测试。仅考虑传导现象，包括连接到公共和工业网络的设备的抗扰度测试。为评估电气和电子设备在承受不平衡电源电压时的抗扰度建立了参考。适用于每相额定线路电流高达16 A的50 Hz/60 Hz三相供电电气和/或电子设备。 本合并版本由第一版（2000年）组成 及其修正案1（2009年）。因此，无须在 本出版物的补充。

IEC 61000-4-27:2000+A1:2009 considers immunity tests for electric and/or electronic equipment (apparatus and system) in its electromagnetic environment. Only conducted phenomena are considered, including immunity tests for equipment connected to public and industrial networks. Establishes a reference for evaluating the immunity of electrical and electronic equipment when subjected to unbalanced power supply voltage. Applies to 50 Hz/60 Hz three-phase powered electrical and/or electronic equipment with rated line current up to 16 A per phase. This consolidated version consists of the first edition (2000) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
