Hi  Jim,

I understand your concerns, but that is exactly why harmonised standards
give only PRESUMPTION of Compliance only.
and not PROOF of compliance.

Definition of presumption:
PRESUMPTION - A fact assumed to be true under the law is called a
presumption. For example, a criminal defendant is presumed to be innocent
until the prosecuting attorney proves beyond a reasonable doubt that she is
guilty.....

It is exactly what has happened in the case of the hair dryers.


I agree BTW the the EN 55014 is an outdated standard ; of which the
modernisation has been witheld by the
hair dryers manufacturers that conveniently use the clamb mathod over a
limited part of spectrum to "get rid of that EMI hassle".

The base problem is that CENELEC ; as being mandated by the EC to produce
harmonised standards; is a partially
incompetent organisation in the sense that the product committees and voting
comittees define and vote standards.
Voting committees and product committees are overcrowded by parties of
interest (read: manufacturers), and the
CENELEC system does not allow for overruling creating an incompetent
standard.

The EC has on several affairs (f.a DOW dates, and "conditional limits")
threathened the CENELEC of withdrawing the
mandats if they would not comply with their requirements, and that has
created some consistence.

Instruction reports exists for product committees  that explicitly address
the situation of "essential EMC phenomena" that need to be addressed in
every harmonized standard; but it is widely "ignored".

The EC not being idiot, has wisely decided that harmonized standards can
therefore give only presumption of compliance.

Same is true for EN 55022 and interference above 1 GHz; just the standard is
not enough.

This is a pitfall especially for USA based manufs as they often look to the
letter of a standard, losing
the overalll view. This is mainly caused by the former rigid system of FFC
and UL approvals, putting
to much responsibility with the test house.

If I were the manufacturer and had enough money, i'dd sue the product
standards committee responsible for
creating this standard, and not covering the full spectrum in spite of the
EMC directive being in force since 1992.

  I read this article with some consternation, since in my mind it
challenges not the manufacturer or importer, but the concept of Presumption
of Conformity (I'll use PofC...).

  Quote:  "If the standard in question only covers some of the EM phenomena,
or is limited in its scope, then full compliance cannot be guaranteed. The
products thus failed the essential protection requirements and were
incorrectly CE marked".

  I am in strong disagreement with that statement.  If the standard in
question only covers some of the EM phenomena, then the standard in question
does NOT provide PofC and should NOT have been published in the OJ or on the
Europa site as a harmonized standard under the EMC Directive.  It is not the
manufacturer's fault if the EU incorrectly publishes references in the OJ
implying PofC where there are essential requirements not covered.  In my
mind, the CE Mark was correctly applied by the mfr, and the fault lies with
EN55014 (which I have always thought is flawed) and with the EU/CEN for
issuing a standard that fails to provide PofC.

  Am I right or am I delusional, naive, misinformed, an idealist, or all of
the above?!?!?

  At the very least, it seems to me that the EU has an obligation to provide
more information.  If a standard is listed as applicable to the EMC
Directive and does not provide PofC, then the standard's preamble and the
Europa listing should say so, and should point out which essential
requirements are not addressed, and which standards should be used to cover
the missing requirements.  I am getting extremely tired of the "let the mfr
figure it out" approach used by the EU.

  Ok, I'll stop whining now.
