Electromagnetic Compatibility Directive (89/336 CEE)

The legislation 89/336 CEE “EMC” of the CEE council, which became law on 1.1.96, has, for the first time, set the requirements and the relative control methods for equipment that can cause electromagnetic radiation or equipment that can be effected by such electromagnetic disturbances (article 2). As these directives are affecting more and more the design and production of electrical and electronic equipment, it is important that the product is created right from the laboratory stage with the standards needed to pass the testing to allow the CE approval mark to be applied.

DENEB Electronics has designed an economics systems for the EMC pre-compliance measurements for use in electronic design laboratories, enabling testing of the electromagnetic compatibility to be done step by step, during the designing, according to the principle that the reliability of a product cannot be added at the end of the design work, but can only be born along with the product.

The standards that the DENEB Systems enables to be made on the equipment under test (EUT) are descript in the table on the right.
