PQR using EN materials listed in sec IX
(OP)
Hi Everyone,
Is it possible use a PQR(prepared acc. to Sec IX) with EN material S235JR (which is listed in Sec IX table QW/QB422 as P1 material) for manufacturing stamped Sec I Boiler or Sec VIII vessel from P1 material (eg SA516)
Is there any restriction etc.

A senior eng. told me if a material not listed in Section 2 tables it cannot be used to qualify WPQR. S235JR not listed Section II D tables.
But i could not find any code reference supporting his argument. Does his argument valid?
