There is an on-going (silent) conflict between the European commission and a number of cenelec and cispr committees, notably those responsible for EN 55032 and EN 55011. While the EC has expressed their opinion in the generic standards, and expressed their desire that all product committees comply with the definitions and limit therein, the market (standard committees) does not comply to that, and the EC lacks power (or will) to change that. Therefore the discrepancy between definitions.
Note that it’s a rather complex matter as the standards are born as Worldwide standards (CISPR) and are “common modified” to EN versions. So CISPR11 (world wide) becomes EN 55011 (Europe harmonised) without changing the “Industrial” definition. Regards, Ing.

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.

I have seen and read varying opinions on what criteria to use. It ranges from a transformer isolated factory to the nature of the other products in the immediate vicinity (a mechanical room in a grocery store = industrial due to the equipment in its immediate environment). I am familiar with some of the definitions in places, but am not so sure that those are what are typically followed in practice. I appreciate any thoughts.
