Has the CE+CE=CE idea been adopted?
Absolutely not in general, only for electrical switchboards, AIUI.

Thanks to everyone that responded to my query. Here is my original question
and a synopsis of the replies.
Question:
We currently design our products to comply with the Class B emissions limits
of EN 55022, but I am getting a lot of pressure from engineering to allow
the limits to be raised to

Although it can be argued that my products are Class A,
we design our products to meet Class B. I have had the
occassion where I was at the limit and was under pressure

I have often wondered exactly why there are two classes in EN55022. The
limits are pretty similar, does a 13dB difference in conducted emission QP
limits really make a difference above 5MHz? I know the 23dB difference
5MHz (conducted emissions) helps with products that have a SMPS, for
example.
Hi Richard,
My business/commercial/industrial ITE clients have usually aimed for Class B
but if they did not get there, Class A hass always been accepted by their
customers. Most customers do not know the difference very few will insist
on Class B (tending toward laoratories and such locations
