John,
Good points and questions. Sounds like a good discussion for CISPR H.
Without interference complaints being noted by regulators and reported to
CISPR there would have to be a significant research project to see if the
existing limits are adequate. I'm not aware of interference complaint
Oh, and one other thing, I sometimes ponder is whether some of the immunity
withstand limits (especially for radiated and conducted RF) for Class B
equipment are higher enough for the "modern world" ,because:

smaller and

On the issue of the "residential" environment, I think that whole issue is
now becoming very blurred in reality with the (at least in the UK) trend to
using former industrial buildings for residential use - as well as the more
general diffusion of the physical barriers between residential and

Might that be a result of a classic case of the FCC/IC position of
specifying emissions but not immunity limits (presumably the Yachtboy is/was
aimed at the European market which does have immunity requirements?

The Class B requirements are intended to offer
adequate protection to broadcast services within
the residential environment.

Hi Ian,
The "residential" environment is generally understood to be the
household/domestic environments where humans typically "reside". With that said
and further into EN 55032 clause 4, there is a subtle and a bit of a loose

Independent of the standards, the EMC directive requires marking on

Unwilling standards committees have been "reluctant" in including the

Ian,
There is no definition of "residential" environment in the standard or the EMC
Guide. For reference, the FCC classifies products into consumer (Class B) and
non-consumer (Class A) categories. In Europe the manufacturer has a similar
responsibility to make a product that meets the EMC req
I suggest you check the Equipment documentation section of the standard for the
reference to the notice.
Also the 10 m separation distance is still referenced therefore there are no
changes in CISPR32 over 22 for these 2 aspects.

Dear colleagues
In the 2015 edition of EN 55032 an interesting statement in clause 4.
"Equipment intended primarily for use in a residential environment shall meet
the class B limits. All other equipment shall comply with the Class A limits."
