In the US I believe it to be exempt as per 15.103(c). Otherwise it will
probably fall under 61326 (lab equipment) or the Generic for light
industrial.

standards question

Morning folks,
A few weeks ago I asked for help finding a quiet MB. Well, I finally have
got boards in and tested.
I can't name names on the list, but, the best MB came from a US, Vancouver
based company.
Two big problems with ALL MB's. Plug in a PS/2 mouse, and the emissions
dramatically increase. Also, this happens with the KB too. It would seem
that the designers of the boards put a switched mode power supply right
next to the connectors: not a smart move in my opinion.
Anyway, this leads me to another question where I could do with some
guidance:
I'm testing a device that basically does HI-Pot testing on electrical
equipment. What classification of equipment is this, and what product
standard would I use to specify the EMC tests to run? I can only believe
that this is light industrial equipment.
Thanks,
