IEC 61000-2-11 Ed. 1.0 b:1999

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.
