Lessons to be learned from Finnish EMC market surveillance projects

The empirical material for this paper was composed from Finnish market surveillance projects that inspected the electromagnetic compatibility (EMC) of products. The projects were carried out between 1997 and 2002 and they were concentrated on equipment groups whose EMC features had been known to be problematic: uninterruptible power supplies, personal computers, frequency converters and energy-saving lamps. In each project, typical products in this group were tested, results were analysed and the reasonableness of products' EMC requirements were evaluated from technical, as well as administrative points of view. In this paper, the lessons to be learned from these projects are discussed.
