Andy: I applaud the direction of your thought, but we should modify it a bit by saying "...no reasonable amount of EMI..." You can't expect a household appliance to withstand 200 or 500 V/M, as if it was a military system. OTOH, 3 V/M is far too low. I would suggest that, for safety critical items, perhaps 50 V/M immunity for residential products would be a good level.
Gas ovens that turn themselves on, even in the presence of a ridiculously positioned cell phone, shouldn't be acceptable.
