I'm not sure that the Generic standards apply. Your products may be within the scopes of EN 55014-1 and EN 55014-2, which, as Product-Family standards, over-ride the Generics. >These test programs are expensive.

Your EMC experts have to decide if a change is likely to affect the EMC performance adversely or not. For example, changing an induction motor probably would not, whereas changing a commutator motor might. If in doubt, you (or the test house) can do 'pre-compliance' tests. -- OOO - Own Opinions Only.
