EMC

The EMC laboratory from the University of Liège performs tests on electrical appliances in conformity with international and European standards. With over 150 industrial references, the laboratory offers services covering the entire process, from product development to certification, ensuring compliance with European Directive 2014/30/EU.

The whole measurement system is either driven by software (for fast full-compliant tests) or manually for R&D. The laboratory is accredited ISO/IEC 17025.
