B31.3 UNLISTED MATERIAL

B31.3 UNLISTED MATERIAL

(OP)
Hi!

I have WPHY70, A694 F70 and API 5L X70 material to be welded to each other and also to P1 Group 1 and 2 materials. WPHY70, A694 F70 and API 5L X70 are all classed as P1 Group 3 in ASME IX but WPHY70 and A694 are not represented in Table A-1 of ASME B313. As they are not listed in B31.3, do I have to carry out impact testing on all material combinations where these WPHY70 and A694F70 materials are used as per B31.3?
