CAN/CSA-CEI/IEC 61000-4-5-01 (R2005)

This National Standard of Canada is equivaent to International Standard CEI/IEC 1000-4-5: 1995 (first edition, 1995-02). This section of IEC 1000-4 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 environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment. The object of this section is to establish a common reference for evaluating the performance of equipment when subjected to high-energy disturbances on the power and interconnection lines. This 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. This standard does not intend to specify the tests to be applied to particular apparatus or systems. Its main aim is to give a general basic reference to all concerned product committees of the IEC. The product committees (or users and manufacturers of equipment) remain responsible for the appropriate choice of the tests and the severity level to be applied to their equipment.
