考虑电磁环境中电气和/或电子设备（装置和系统）的抗扰度测试。只考虑传导现象，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不平衡电源电压下的抗扰度提供参考。 适用于50 Hz/60 Hz三相供电电气和/或电子设备，每相额定线路电流高达16 A。

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.
