WG 1 - TC 77/SC 77C/WG 1

Provides the basic reasons behind HEMP testing and gives a brief description of the most important concepts for shielding element testing. For each test, the following basic information is provided: - theoretical foundation of the test (the test concept); - test set-up; - required equipment; - test procedures; - data processing.

Defines the high-altitude electromagnetic pulse (HEMP) conducted environment that is one of the consequences of a high-altitude nuclear explosion. Establishes a common reference for this environment in order to select realistic stresses to apply to victim equipment for evaluating their performance. Presents the conducted HEMP environment induced on metallic lines, such as cables or power lines, external and internal to installations, and external antennas.
