Design, Implementation, and Evaluation of Proficiency Testing in EMC Surge Immunity

Interlaboratory comparisons and proficiency testing are receiving increasing attention by electromagnetic compatibility (EMC) test and calibration laboratories due to the need for accreditation according to ISO/IEC 17025. In EMC, the proficiency testing offer is restricted to a few test standards, mostly emission. In order to increase this offer, we recently developed a novel equipment that enables the assessment of the test capabilities of laboratories for IEC 61000-4-5 (surge immunity). This article presents an overview of this reference equipment and its capabilities, as well as the interlaboratory comparison recently realized in Switzerland.
