(OP)
Please advise me about this issue: I have an order to manufacture welded structure from steel with inspection certificate type 3.2. May I replace this certificate with type 3.1 and additional accredited laboratory retesting: tensile testing, impact testing and ladle analysis (acc. EN 10025-3). In affirmative case, I would like to know if for tensile testing is enough one test piece for each heat no. (up to 40tons). In EN 10025-1 clause 9.2.2.1 is written that one sample for each test unit must be used. Does this mean that also one test piece is enough for tensile testing?
Many thanks in advance.

I think that the clause that you are looking at says 'at least one sample', your lot size may require more. In some specs it is based on both weight and pieces.
If you move to a spec type that is more restrictive then you are fine. I don't recall the hierarchy in this case.
