Establishes a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. The test method documented in this part of IEC 61000-4 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.The standard defines:- test voltage waveform;- range of test levels;- test equipment;- verification procedures of test equipment;- test set-up;- test procedure.The standard gives specifications for laboratory and post-installation tests.The contents of the corrigenda of August 2006 and June 2007 have been included in this copy.
