Hi Kevin,
I am inclined to side with the regulatory authority.  If you have a
device that has an R&TTE component in it, than that directive applies.
Since the R&TTE Directive requires compliance to the EMC and LV
directives in order to declare conformity to it, it is not necessary to
declare to them individually.  If the R&TTE Directive did not require
conformity to either the EMC or LV directives, then those would have to
be applied and declared to separately.

Subject: R&TTE DoC Philosophy Question


Hello,

I just had an interesting conversation with the head of a approvals
authority for a country in Europe for our type of products. The
discussion
centred around DoCs for the R&TTE directive. His claim was since I had a
product that has a R&TTE element to it then I just make a declaration to
the
R&TTE directive and not to the EMC directive. To support his claim he
refers
to Article 3.1(b) of the R&TTE directive which states "1.The following
essential requirements are applicable to all apparatus"  and part (b)
"the
protection requirements with respect to electromagnetic compatibility
contained in Directive 89/336/EEC. His interpretation is, then, that any
standard published in the OJ for the EMC standard is (by this clause)
also
valid for the R&TTE directive and one should make their declaration
accordingly.

My interpretation of this statement is slightly different. I believe
that I
cannot make an R&TTE directive DoC using EMC published standards. I felt
that the intention of this clause meant that just because you are
declaring
to the R&TTE directive you are in no way relieved of the obligations of
the
EMC directive. Accordingly we produce a EMC declaration and a R&TTE
declaration. The EMC declaration uses standards published in the EMC OJ
to
show compliance and the R&TTE directive DoC is to the standards
published in
the OJ for that directive.

In the end I suppose this is all semantics as you end up doing the same
test
suite regardless but........
What are the feeling of this group. Do you agree with either position?
Do
you have another interpretation?
