IEC 61000-4-5 Testing – Surge Immunity

The scope of IEC 61000-4-5 testing and EN 61000-4-5 testing 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 equipment.

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

The IEC 61000 4 5 test standard defines:

  • a range of test levels
  • test equipment
  • test setups
  • test procedures

EN 61000-4-5 surge testing defines the task of the described laboratory test as 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 IEC 61000-4-5 compliance testing. IEC 61000-4-5 immunity tests do include specific instructions on power switching transients, lightning transients and simulation of transients.
