AS9102 - What needs to be Bubbled on a Contract or Purchase Order

My Customer's interpretation of AS9102 requires our inspectors to bubble the Customer PO as well as the Engineering drawing. This request is to include specifications called out within the PO.

I don't see anything in AS9102 other than to assure that the parts meet the engineering characteristics.

Should I bubble those specifications called out in the Customer PO although some do not pertain to engineering characteristics?

Re: First Article What needs to be bubbled from a Contract

I believe that AS9102 requires that everything identified on the drawing be identified on the forms 1,2 and 3.

However, if your customer sees it a different way then I would have them modify the PO/Contract to reflect their way. :)

If there is a conflict between drawing and PO the face of the PO is legally binding.

Just my opinion.


We only bubble the print characteristics with numbers for each. Forms 1 and 2 are filled out from the PO and print as well but nothing is bubbled on the purchase orders.

If the PO supersedes something bubbled on the drawing, I would add that in the comment for that bubble.


We normally cover such things with our Certificate of Conformance, adding in any special callouts on the PO, but I also have had customers put dimensional changes on a PO and we added them to the AS9102 form three.

It was what I consider a work around for the buyer when production wanted a change (pilot hole position tolerance was added) but it takes to long to get a drawing rev. through the system.

Let us know how this turns out for you J Allen.
