Steve, From the IPC perspective, 9252A supersedes 652. 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 Yes you should stop stating that you have met 652, because to do so places a cancelled/superseded document, as well as, all of the related policy/procedure in your document control system; that's never fun.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?
