(OP)
In welds of dissimilar metals as above, what criteria is recommended for an ASTM G48 method A corrosion test. What acceptance criteria would you specify?

I would not use G48 A or B, use one of the newer methods with the acidified solution. They are more repeatable.
It might be even easier to use an electrochemical test for this. You can control the face exposure that way.

edstainless,
Is there a standard that covers the electrochemical test?

There is a ASTM for it, G150.
I can put you in touch with someone that does this work.
