Electromagnetic Compatibility Laboratory
The CEM laboratory from the University of Liège performs tests on electrical appliances in conformity with the International and European standards. The laboratory has more than 150 industrial references and provides testing services of their products in compliance with the 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 (see also the annex).
In addition to compliance tests, we provide
- competence on standards;
- precompliance tests.
