Electro-Magnetic Compatibility (EMC)
All manufacturers / assemblers of electrical apparatus which "performs a complete
intrinsic function and is placed on the market as a single unit intended for the end user"
must comply with the EMC directive EEC/89/336.
There are three routes for the manufacturer/assembler to demonstrate compliance:
This is a manufacturer's declaration that the European standards applicable to the
electrical environment for which the apparatus is intended have been met. Only
standards that have been officially published in the Official Journal of the European
Community can be cited in the manufacturer's declaration.
Technical Construction File
A technical construction file can be prepared for the apparatus describing its EMC
characteristics. This file must be approved by a 'Competent Body' appointed by the
appropriate European government organization. This approach allows the use of
standards that are still in preparation.
EC Type Examination Certificate
This approach is only applicable to radio communication transmitting apparatus. All
MICROMASTER units are certified for compliance with the EMC directive, when installed
in accordance with the recommendations in Section 2.
