One
of the most important markets in the world is the European Economic Area ,
which includes the European Free Trade Association
and the European Union countries, that
with its nearly
500 million inhabitants is one of the most important market
in the world. After
the enlargements of 2004 and 2007, it
is possible
that other countries
like Croatia, F.Y.R.O.M. and Turkey are trying to become membership
in the EU; so
these countries must make
similar their
political and economic structures to that of the European Union. This
includes the adoption of directives and standards mandatory in the EU. There
are Directives regarding Electromagnetic Compatibility (EMC), Low Voltage
equipment, Machinery and Medical Devices that have a major impact on
European and Global industries selling products in this region of the
World. New
requirements regarding Electromagnetic Compatibility
and safety have to meet the European legislation, so that they
comply with these Directives. European
norms are in general based on or adopted from the International
Electrotechnical Commission (IEC) standards. Approximately
60 member countries create IEC standards with the input of their national
standards working groups and committees. The
United States is represented through the American National Standards
Institute (ANSI) and is very
interested to
a variety of standards such as IEC 60950, IEC 61010 and IEC 60601. These
IEC standards have been harmonized as European Norms (EN) with the same
numbers EN 60950, EN 61010, EN 60601 plus very limited European Amendments
which reflect
national conditions. The
CE marking, that
is similar to the one
used by Chinese companies, is
supposed to
make easy the free
movement of goods within the European Union and
guarantees that
products meet
the requirements of directives issued by EU and standards are
respected. There
are directives some adopted
other ones to be
written that set out
mandatory technical and safety requirements for a variety of products,
including appliances, electrical machines, medical devices, passenger
lifts, telecommunications products, recreational boats and children's toys. Equipment
today must be designed for the global market with safety and EMC
compliance in mind. For
EMC, both emissions and immunity issues must be addressed. Typical safety
design issues to consider are creepage and clearance distances, the use of
components with third party approval, printed circuit board layouts,
transformer design and construction, insulation thicknesses, safety
interlocks and protective earth grounding. Many
of these items are easily incorporated in new designs but often become
serious issues when one is faced with the redesign of existing products
because of limited enclosure space, EMC compliance issues and the use of
specially designed components. It
is important to recognize the appropriate standards that need to be met.
EN 50081-1, Generic Emission - Residential, commercial and light industry,
EN 50082-1, Generic Immunity - Residential, commercial and light industry
and for safety EN 60335-1, Safety of household and similar electrical
appliances - General requirements, along with the EN 60335-2-xx series are
the applicable standards for appliances. Manufacturers
should evaluate their technical construction files and declarations of
conformity to verify that EMC and Product Safety tests have been carried
out for the complete product.
