This standard EN 61000-4 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 environmental and installation conditions. These requirements are developed for and applicable to electrical and electronic equipment. The object of this section of standard EN 61000-4 is to establish a common reference for evaluating the performance of equipment when subjected to high energy disturbances on the power and interconnection lines. The standard defines: - range of test levels; - test equipment; - test set-up; - test procedure. The task of the described laboratory test is to find the reaction of the EUT under specified operational conditions caused by surge voltages from switching and lightning effects at certain threat-levels. It is not intended to test the capability of the insulation to withstand high voltage stress. Direct lightning is not considered in this standard.
