I have a PQR tested and approved by Bureau Veritas, in conformance with the requirements of clause 4 of AWS D1.1.
I've sent to client a WPS where I write "reference standard ISO 15614".
Is that a mistake? Because I can't find nothing in the rules.
First thing you must do is check the required testing requirements between the two codes.
If the requirements of ISO 15614 exceed the requirements of AWS D1.1 then you cannot try and substitute.
It is up to your client if an alternative WPS is acceptable but if you haven't done enough testing you are wasting your time,
