|| P-IEC 61000-4-5 ed2.0 withdrawn corrigendum
|| Electromagnetic compatibility (EMC) - Part 4-5: Testing and
measurement techniques - Surge immunity test
||Relates to the immunity requirements, test methods, and range of
recommended test levels for equipment to unidirectional surges
caused by overvoltages from switching and lightning transients.
Several test levels are defined which relate to different
environment and installation conditions. These requirements are
developed for and are applicable to electrical and electronic
The object of this standard is to establish a common reference for
evaluating the immunity of electrical and electronic equipment when
subjected to surges. The test method documented in this part of IEC
61000 describes a consistent method to assess the immunity of an
equipment or system against a defined phenomenon.
This standard defines:
- a range of test levels;
- test equipment;
- test setups;
- test procedures.
The task of the described laboratory test is to find the reaction of
the EUT under specified operational conditions, to surge voltages
caused by switching and lightning effects at certain threat levels.
It is not intended to test the capability of the EUT's insulation to
withstand high-voltage stress. Direct injections of lightning
currents, i.e, direct lightning strikes, are not considered in this
