[MW:28362] evaluating of micro structure

Dear All.

Does anybody know how it is possible to evaluate the bainite or martensite of the base metal is tempered or not?
I want to know the method , frequency of testing, acceptance( such as figures) and any other issues that can say with confidently we have tempered micro structure or not?
as you know this is more crucial in sour service and is a requirement in our specification but doesn't mention detail of it.

Regards.
