1 Scope
The purpose of this part of IEC 61000 is to describe the effects that have occurred during actual and simulated electromagnetic
pulse testing throughout the world. These effects include those observed during the
high-altitude nuclear tests conducted by the United States and the Soviet Union in
1962, and the HEMP simulator tests conducted by many countries during the years after
atmospheric testing ended. In addition to direct effects, this technical report also
contains information on HEMP coupling to “long lines” as it is important to verify
that particular levels of currents and voltages can be induced by HEMP on these lines;
this provides a basis for direct injection testing of electronic equipment. It should
be noted that, in most cases, the electrical equipment tested or exposed did not contain
the sensitive electronics in use today. Also it should be emphasized that all tests
and exposures did not produce failure of the equipment; factors such as the geometry
of the HEMP interaction and the electromagnetic shielding of the equipment are variables
that can produce differing results. The description of these effects is intended to
illustrate the seriousness of the possible effects of HEMP on modern electronic systems.
