John - I remember people trying to argue their product was ISM (when it was clearly not ISM) and use EN 55011 Class A limits because they did not want to use the light industrial generic emissions limits, and in those instances I would agree with you.
I would disagree with you for instances where you based compliance around the generic standards' requirements because your product standard did not address a phenomena that was addressed in the generic standards, provided that the generic standard was appropriate to your operating environment.
