My understanding has always been based on the Class and Group designations in CISPR 11 / EN 55011 for ISM equipment (based on the 2009 edition):
> 5.3 Division into classes > Class A equipment is equipment suitable for use in all establishments other > than domestic and > those directly connected to a low voltage power supply network which supplies > buildings used > for domestic purposes. > > Class A equipment shall meet class A limits. > > Warning: Class A equipment is intended for use in an industrial environment. > In the > documentation for the user, a statement shall be included drawing attention > to the fact that > there may be potential difficulties in ensuring electromagnetic compatibility > in other > environments, due to conducted as well as radiated disturbances. > > Class B equipment is equipment suitable for use in domestic establishments > and in > establishments directly connected to a low voltage power supply network which > supplies > buildings used for domestic purposes. > > Class B equipment shall meet class B limits. The key in all of this is the source of power supply for the equipment. If the equipment is supplied from mains that are shared with domestic establishments, then it must meet Class B requirements IMO. If the equipment is intended for industrial use, i.e., Class A, where the power supply from the mains is not shared with domestic establishments, then Class A performance is acceptable. The deciding factor is the sharing of the supply with domestic establishments. If a location is fed from its own substation and there are no dwellings supplied from that substation, it’s an industrial location, and therefore Class A.
