EMC Directive:
The EMC Directive was adopted in 1989 and then amended in 1992
(92/31/ECC) and 1993 (93/68/EEC). It is regarded as one of the most complex
"new approach" directives, as it affects almost all electronic
manufacturers and products (including battery-supplied products going to the
European Union).
The EMC Directive applies to apparatus, systems, equipment, and installations
containing electrical or electronic components.
Definitions
"Apparatus" is defined as a final product with an intrinsic function
intended for the final user and intended to be placed on the European Union
market as a single commercial unit.
"Equipment" is equivalent to "apparatus."
"System" is defined as several apparatus combined to fulfill a
specific function and intended to be placed on the European market as a single
functional unit.
"Installation" is defined as several apparatus or systems combined at
a given place to fulfill a specific function, and not intended to be
placed on the European market as a single functional unit.
"Electromagnetic Compatibility" (EMC) is defined as the combination
of electromagnetic emissions and immunity.
An "emission" is defined as electromagnetic energy emitted by a
device/product over a power line or through the air.
"Immunity" is defined as the ability of a device/product to not
be influenced by the application of electromagnetic energy from external
sources.
