EN 61000-4-5 EMC Surge Immunity Testing of Radio-Frequencies

The scope of EN 61000-4-5 testing relates to the immunity requirements. EN 61000-4-5 also relates to the range of recommended test levels for equipment to unidirectional surges. These are 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 apply to electrical and electronic equipment.

EN 61000-4-5 testing establishes a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The EN 61000-4-5 test method assesses the immunity of an equipment or system against a defined phenomenon.

The EN 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 reaction of an 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 EN 61000-4-5 compliance testing. EN 61000-4-5 immunity tests do include specific instructions on power switching transients, lightning transients, and simulation of transients.
