EMC directive
(89/336/EEC)
One of the EU directives that FSC complies with is the EMC
directive, or Council Directive 89/336/EEC of 3 May 1989 on the
approximation of the laws of the Member States relating to
electromagnetic compatibility as it is officially called. It "applies to
apparatus liable to cause electromagnetic disturbance or the
performance of which is liable to be affected by such disturbance"
(Article 2).
The EMC directive defines protection requirements and inspection
procedures relating to electromagnetic compatibility for a wide range
of electric and electronic items.
Within the context of the EMC directive, 'apparatus' means all
electrical and electronic appliances together with equipment and
installations containing electrical and/or electronic components.
'Electromagnetic disturbance' means any electromagnetic phenomenon
which may degrade the performance of a device, unit of equipment or
system. An electromagnetic disturbance may be electromagnetic noise,
an unwanted signal or a change in the propagation medium itself.
'Electromagnetic compatibility' is the ability of a device, unit of
equipment or system to function satisfactorily in its electromagnetic
environment without introducing intolerable electromagnetic
disturbances to anything in that environment.
There are two sides to electromagnetic compatibility: emission and
immunity. These two essential requirements are set forth in Article 4,
which states that an apparatus must be constructed so that:
(a) the electromagnetic disturbance it generates does not exceed a
level allowing radio and telecommunications equipment and other
apparatus to operate as intended;
(b) the apparatus has an adequate level of intrinsic immunity of
electromagnetic disturbance to enable it to operate as intended.
The EMC directive was originally published in the Official Journal of
the European Communities on May 23, 1989. The directive became
effective on January 1, 1992, with a four-year transitional period.
During the transitional period, a manufacturer can choose to meet
existing national laws (of the country of installation) or comply with
the EMC directive (demonstrated by the CE marking and Declaration
of Conformity). The transitional period ended on December 31, 1995,
which meant that as of January 1, 1996 compliance with the EMC
directive became mandatory (a legal requirement). All electronic
products may now only be marketed in the European Union if they
meet the requirements laid down in the EMC directive. This also
applies to FSC system cabinets.
