本出版物的目的是帮助规定包含电气或电子部件的物品（如设备或子系统）的抗扰度要求，以确保其在暴露于高空电磁脉冲（HEMP）波形期间和/或之后运行。它为包含可能受电磁信号干扰电路的任何组件、装置、设备、子系统或系统的抗扰度测试水平的选择提供了基本指导。

The purpose of this publication is to help specify the immunity requirements of an item (e.g. equipment or subsystem) containing electrical or electronic parts to ensure that it will operate during and/or after exposure to a high-altitude electromagnetic pulse (HEMP) waveform. It provides basic guidance for the selection of immunity test levels for any component, device, equipment, subsystem or system which contains electrical circuits that may be disturbed by electromagnetic signals.
