42、hods forelectrical and electronic equipment and systems exposed to high-altitude electromagneticpulse (HEMP) environments. It defines ranges of immunity test levels and establishes testprocedures. Specifications for test equipment and instrumentation test set-up, test procedures,pass/fail criteria,
43、and test documentation requirements are also defined by this standard.These tests are intended to demonstrate the immunity of electrical and electronic equipmentwhen subjected to HEMP radiated and conducted electromagnetic disturbances. For radiateddisturbance immunity tests, specifications are defi
44、ned in this standard both for small testfacilities and large HEMP simulators.This part of IEC 61000 defines specifications for laboratory immunity tests. On-site testsperformed on equipment in the final installation to verify immunity are also specified. Theseverification tests use the same specific
45、ations as laboratory tests, except for the climaticenvironmental specifications.The objective of this part of IEC 61000 is to establish a common and reproducible basis forevaluating the performance of electrical and electronic equipment, when subjected to HEMPradiated environments and the associated
46、 conducted transients on power, antenna, andinput/output (I/O) signal and control lines.2 Normative referencesThe following normative documents contain provisions which, through reference in this text,constitute provisions of this part of IEC 61000.
