IEC 61000-4-5 relates to the immunity requirements, test methods, and range of recommended test levels for equipment regarding unidirectional surges caused by overvoltages from switching and lightning transients. Several test levels are defined which relate to different environments and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment.

The object of IEC 61000-4-5 is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented in IEC 61000-4-5 describes a consistent method to assess the immunity of equipment or systems against a defined phenomenon.

IEC 61000-4-5 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 equipment under test (EUT) under specified operational conditions to surge voltages caused by switching and lightning effects. 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 standard. The text of IEC 61000-4-5:2014 has been approved in Europe as EN 61000-4-5:2014 without any changes.
