Not exactly. The question was strictly about 'Class', which of course
can mean different things in different standards, but my answer is, I
think, correct for Europe. Intentional radiation is excluded from the
CISPR standards and is covered by the ETSI standards cited by Charlie
Blackham.

John,
Are you saying that a product with intentional radiator only needs to
meet Class A for emissions in EU? i.e there is no difference in terms
of the limit between intentional and unintentional radiators when it
comes to EU. Is that a correct statement?
Thanks
Peter

That should be CISPR 35, not CISPR 24 now. In Europe, it would be
Class A. The manual should say 'This product is not to be used in a
residential environment.'.

To give a reliable answer, we need to know the type of product or the
EMC emission standard that applies (e.g. CISPR 14-1/EN 55014-1) and
which countries/regions it will be sold in.

Dear Colleagues,
I have a client that design and manufacture products for use in
non-residential environment. This product consists of a BT module. I
am told that the product must meet Class B emissions. Is this correct?
What if we put an statement in the user manual stating that this
product is not to be used in residential market? Would that give us
the pass to go to Class A?
Thank you all
Peter
