Acceptance criteria for P8 PQR

[MHMaterials]

Hello,
I'm reviewing a PQR and the tensile test report specified the fracture of both specimens in weld metal. I recall that it's not correct to fail in weld material, fail should be in base metal...
I'm trying to find the acceptance criteria that tells me it's incorrect to have the welding fail but QW-153 (ASME IX) didn't got me the answer I was expecting.

Material is P8-P8 (SA240 - 304).

Can anyone point me in good direction or specify if I'm wrong in my understanding?
Thanks in advance.

Tensile test may fail in the weld metal. It's accepted as long as the minimum specified tensile strength of the base metal is achieved.

Agree with stanweld. ASME Section IX QW-153.1 is very clear with the tension test criteria listed in (a) through (e).

Agreed, but you want to ensure that you have a ductile failure, rather than a brittle fracture mode in the weld metal.

Thanks guys, I just had that in mind (for some reason) that it wasn't good to fail in the weld, but after reading it I along with your comments is more clear for me now.
