I would say it depends a lot more on your trust of the vendor. I have seen C of C's that were absolutely worthless. Simply paper that was spit out automatically and had no basis in reality. All a C of C document is, in my opinion, a document that the lawyers use after the disaster has happened. What you want is independent test data, not a C of C.

However, ultimately the answer to your question depends upon the transition policy of your individual contracts. In the absence of transition policy (likely), I would suggest that the prescribed form provided by 9252 gives you better legal standing for a CofC. You will also find verbiage from IPC/TAEC as to the transition intent. Yes you should stop stating that you have met 652, because to do so places a cancelled/superseded document, as well as, all of the related policy/procedure in your document control system; that's never fun.

On a related subject, should the vendor stop stating they have met ET-652 and state that they have met 9252A?
