Electromagnetic compatibility
Electromagnetic compatibility (EMC)
All manufacturers/assemblers of electrical units which "perform an essentially complete
function and are marketed as a single unit designed for the end-user", must comply with the
EMC Directive 89/336/EEC.
There are three ways for the manufacturer/assembler to verify compliance:
Self-certification
The manufacturer declares that the European standards applicable to the electrical
environment for which the unit is intended are satisfied. Only standards which have been
officially published in the official journal of the European Union are allowed to be cited in the
manufacturer's declaration.
