EN55022 is currently the relevant product family specification, hence the
generic specification have no relevnace. EN55022 clearly states that class
B is for equipment intended "primarily" for the residential/domestic
environment and class A is for all other locations.
Hence the Germany government [or any other] can not impose class B when
EN55022 states class A ! Yes there is the problem of home office type
situation but the specification does state "primarily" intended for home use !
What a manufacturer must be aware of is what are the demands of his customers.
If EN55022 changes or a different relevant specification is issued then
this situation may obviously change !
