Ken,
my experience with the CE-marking (EMC, Low Voltage Directive) is, that many
manufacturer just apply the CE-mark and write a declaration of conformity.
The products do often not comply with even the basic safety or EMC
requirements.
Critical is, when you are buying components like power supplies, controllers
for machines etc. Then the producer of the end product has the liability risk,
but there are components and assemblies built into the product which are in
best case not safe.
Within the EU the controls are not very sufficient and therefore the risk to
get trapped is almost 0. The best way is to ask the supplier to send the test
report with the component. Therefore I agree fully with your statement.
Best regards

Betreff: RE: Meaning of CE mark
Ken
The CE Marking as such simply means that the manufacturer/importer CLAIMS that
the equipment complies with those DIRECTIVES (not specifically the relevant
standards) which both apply to it and require the marking to be applied - thus
it might, or may not, even correctly address EMC for a non-electrical product
(of which there are many which require to be marked).
Effectively, from a standards compliance perspective, it conveys nothing
without the Declaration of Conformity (DoC)which is where the standards SHOULD
be stated with full titles and dates - but often are not!. You might find that
information in the manuals - but that is not obligatory. Again, even then,
some standards have several "pass" levels/criteria - so for "real" information
on the levels met and the methods of conducting the tests, you actually need
to see the test reports which will almost certainly NOT be delivered with the
product (and for which you will probably need to sign an NDA - if the supplier
will even let you see them as he has no basic legal obligation to do that
either unless you are the enforcing authority and there is perceived
non-compliance!).
On balance, the CE Marking requirements have actually achieved quite an
improvement in compliance performance - but, unless you are confident in the
capabilities and track-record of your suppliers, a large "pinch of salt" may
be required when assessing the compliance of 3rd party products and their
effects on the compliance of your own systems into which you are integrating
them.

Subject: Meaning of CE mark
List Members,
My understanding is that while an FCC mark on equipment means it has been
tested and found compliant with relevant EMC limits, the CE mark does not
imply the same thing. The CE mark may only mean that the manufacturer
claims compliance with relevant EMC limits, but he may make that claim
without any test data.
Is this synopsis correct, and if so, can one tell by inspecting the owners
manual or other paperwork delivered with the product whether testing was
actually accomplished or not?
Thank you,
Ken Javor
