This part of IEC 61000 describes the immunity test levels and related test methods for
electrical and electronic equipment and systems exposed to high-altitude electromagnetic
pulse (HEMP) environments. It defines ranges of immunity test levels and establishes test
procedures. Specifications for test equipment and instrumentation test set-up, test procedures,
pass/fail criteria, and test documentation requirements are also defined by this standard.
These tests are intended to demonstrate the immunity of electrical and electronic equipment
when subjected to HEMP radiated and conducted electromagnetic disturbances. For radiated
disturbance immunity tests, specifications are defined in this standard both for small test
facilities and large HEMP simulators.
This part of IEC 61000 defines specifications for laboratory immunity tests. On-site tests
performed on equipment in the final installation to verify immunity are also specified. These
verification tests use the same specifications as laboratory tests, except for the climatic
environmental specifications.
The objective of this part of IEC 61000 is to establish a common and reproducible basis for
evaluating the performance of electrical and electronic equipment, when subjected to HEMP
radiated environments and the associated conducted transients on power, antenna, and
input/output (I/O) signal and control lines.
