I'll try to give this a shot.

It is against the law to sell products in Europe which do not meet each
country's safety and EMC regulations.  These regulations have been
harmonized across the EC by use of the EN standards (EN 61010, etc.)  The CE
mark is YOUR claim that a product meets all the applicable standards for its
product family.  You can self certify (do your own tests, hire a test lab,
etc.), which means that YOU are responsible for defending your evidence
should your CE marking ever be challenged.  You can also hire a group like
TUV to certify (third party) your application of the CE mark.  They bring
their wisdom, expertise, and cachet to the table, and take much of the legal
burden off of you.  This is perhaps advisable if you are not well schooled
in these standards.  It is not, however, required that you take this route.
First thing to do is hook up with a reputable test house, as you will need
them in any case to do a lot of the testing.  Then, you can decide to bring
in a Competent Body or not.

Hope this helps.

Dear Group,

I'm just getting started in the world of EMI and would like to ask a few
questions.  I'm not sure if I should be going the TCF route or the Standards
Route.  The company that I work for manufactures products which have many
variants.


1)  Is it EC law that a manufacturer must perform EMI testing before
applying the CE mark?

2)  If a manufacturer follows the Standards Route, does EC law require each
variant to be tested? 

3)  If, when testing, the limit is exceeded, can the CE mark still be
applied?

4)  Are the services of a Competent Body required in order to put together a
TCF or can the manufacturer do that on his own?


Thanks in advance,
Joseph C. Fries
