| Our company has quite a few directives in
its archive and we use them in order to give you up-to-date
advice on the current EMC-regulations in the EU.
These directives are not free of charge and can be acquired
through IEC.
EMC Directives - History
The European union is a front runner
in the development of EMC regulations. Already before the
second world war countries like Germany, France, the Netherlands,
Belgium and the United Kingdom formed the CISPR (Comite International
Special des Perturbations Radioelectriques) dealing with the
emission of electric appliances and the ir potential interference
problems. CISPR still exists and the CISPR emission norms
of today are used as the basis for the unified IEC and EN
norms on emission.
In 1984 CENELEC (Comite Europeen de Normalisation Electrotechnique)
was given the assignment by the EU to study and develop the
European standards. As a result they published standards for
emission, immunity and safety. Tests on these 3 are all compulsory
now but emission is perhaps in general terms the most essential.
Emission is based on the principle of "Thy shall not
disturb others". Immunity is concerned with possible
failure of the apparatus as a consequence of the influence
of another instrument. Safety refers to electrical safety,
for example the protection from the high voltage towards the
user of the apparatus.
There is a great diversity of standards available at the moment
and when an apparatus complies with the standards relevant
to it, this can be considered an important element in the
quality assessment process. CE compliance is highly regarded
throughout the whole world. European laws are in most cases
the most severe and complete standards available. Manufacturers
are of course allowed to use even more severe standards but
at least compliance with European standards guarantees a place
for your electrical appliance on the European sales markets.
