immunity test methods for equipmentand systems.

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.
