SA-516-70 without impact requirements must comply with ASME VIII-Div.2. Material is supplied by stocker. Posibities: a) Material manufacturer shall supplement the MTR to comply and specify with AM 101; b)stampholder shall review the MTR to verify whether the requirements of the SA specification are complied with and
whether the requirements of Part AM and any other supplementary
requirements of Section VIII, Division 2 are complied with. This second alternative means material complies with AF-101. In this case the stamp holder shall certify the compliance with AM 101 on the MTR or on a supplementary page if really it is verified all requirements of AM are complied?.
Considering alternative b) could be simply be made with a note saying ex. "this material complies with AM-101" and signature by Quality Control Manager?, Others ways?

Hello, Jose,
There is no UG-10 in Section VIII Div. 2. Only the material manufacturer can certify the material, and this needs to be a CMTR. You have to go a).

Dear Dirk,
Nice to hear you.
I don´t agree totally with your answer, because on 04/02/02 Michael replied me as follows:
"If material from stock is used for vessels according to Section VIII,
Division 2, either the material manufacturer shall supplement the MTR to comply with AM 101 or the stampholder shall review the MTR to verify whether the requirements of the SA specification are complied with and whether the requirements of Part AM and any other supplementary requirements of Section VIII, Division 2 are complied with. In this case the stamp holder shall certify the compliance with AM 101 on the MTR or on a supplementary page." I agree Michael.
In this way not only one possibility exists. In last phrase of AM-101 is said: "All conflicts between the material specification and the special requirements herein shall be noted and compliance with special requirements stated (see AF-101)."

Please find a reply below, which should be our guideline for the time being:

Only the material manufacturer can certify whether all requirements of the materials specification and all special requirements of Part AM which are to be fulfilled by the materials manufacturer have been complied with. The vessel manufacturer – being unaware how the material manufacturer made the material and the tests on the material - doesn’t know these things and as such cannot supplement or upgrade a MTR to a CMTR.

Besides, the title and the text of § AM-101 refers only to the material manufacturer.
On the other hand, if the vessel manufacturer can proof that there are no special provisions out of ASME Section VIII, Div. 2 to be taken care of, and all the requirements of the material specification fulfil as such also directly all the requirements of Section VIII, Div. 2, the normal certification on a MTR (by the material manuf.) would be acceptable. This practice (proof of correspondence between the material specification and Section VIII, Div. 2) could be confirmed by the vessel manufacturer.

I also want to refer to § AM-105.1 where it is said that standard pressure parts do not need certification to AM-101 and as such can easily be taken from stock.

Best regards,
