Well....there are some cord attributes found in Article 422 but those are for appliances that are permitted to be cord and plug and such, to paraphrase of course.Very true. Still wouldn't be a bad idea to have Breakaway chords on coffee pots, I know my Fry Daddy only has like an 18 inch long cord and it is a breakaway type. 190 degree water or 400 degree oil, either way I don't want to come in contact with either.
I don't suppose it is possible to submit such proposals as appliances are outside the scope of the NEC?
In your case it would be better directed to the UL Standard for the actual appliance standard since you are referring to coffee pots and fry daddy type appliances which you are correct in thinking the NEC doesn't govern.
