This technical report defines how protective devices for High
Altitude Nuclear Electromagnetic Pulse (HEMP) protection of
civilian systems are specified. Performance requirements will be
given in future IEC standards. This technical report is intended to
be used for the harmonization of existing or future specifications
issued by protective devices manufacturers, electronic equipment
manufacturers, administrative bodies and other buyers.
This technical report covers protective devices currently used for
protection against HEMP radiated EM fields. In general, parameters
relevant to HEMP, that is parameters related to very fast changes
of EM fields, as a function of time, are dealt with.
