I pose the opposite problem: a term that does in fact exist in the FAR but, in my humble opinion, should be revisited. When I first started in contracting (only a couple of years ago) I was so confused when a teacher referred to "data other than certified cost and pricing data," and then proceeded to give examples of what it was. It looked just like...lo and behold...CERTIFIED cost and pricing data. In my limited experience, it is rarely anything other than cost and pricing data that simply has not been certified.
I would love to see them rename it "uncertified cost and pricing data" or maybe "cost and pricing information." Does anyone else find this term irksome?
