A new edition of IEC 61000-4-5 has been published by the International Electrotechnical Committee. IEC 61000-4-5 applies to “Electromagnetic compatibility (EMC) – Part 4-5: Testing and measurement techniques – Surge immunity test.” The new edition is available for purchase on the IEC’s website.
“IEC 61000-4-5:2014 relates to the immunity requirements, test methods, and range of recommended test levels for equipment with regard to unidirectional surges caused by over-voltages 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 standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.”
