In service Inspection

[blaqesmith]

Dear experts please suggest me solution for following issue

I am inspecting a vessel as per API 510. Vessel name plate shows that it was manufactured on british standard but its material identification is not available. Infact no other documents are available. Please tell me what i will have to do? Should i move to material testing or any other solution exist?
