A wide range of legislation and of harmonized standards have come into force and been published
in the field of EMC in the past few years. In the European Union, the EMC Directive 89/336/EEC of
the Council of the European Communites has come into effect on the 1st of January 1996. As of
this date, all electronic equipment must comply with the protection objectives of the EMC Directive.
The conformity with the respective standards must be guaranteed by the manufacturer or importer
in the form of a declaration of conformity. A CE mark of conformity must be applied to all equipment.
As a matter of principle, all electrical or electronic equipment, installations and systems must meet
the protection requirements of the EMC Directive and/or national EMC legislation. A declaration of
conformity by the manufacturer or importer and a CE mark are required for most equipment. Excep-
tions to this rule and special rulings are described in detail in the EMC laws.
New, harmonized European standards have been drawn up in relation to the EEC’s EMC Directive
and the national EMC laws. These specify measurement procedures and limit values or test sever-
ities, both for interference emission and for the interference susceptibility (or rather, immunity to in-
terference) of electronic devices, equipment and systems.
The subdivision of the European standards into various categories (cf. following table) makes it
easier to find the rules that apply to the respective equipment.
The generic standards always apply to all equipment for which there is no specific product family
standard or dedicated product standard.
The basic standards contain information on interference phenomena and general measuring
methods.
