Hardness - PQR Qualification - Acceptance Criteria for Weld Metal

[Sham Shahabuddin -Welding Inspector, HANBO]

Dear Experts

Can anyone explain about the Acceptance criteria of Hardness for the weld metal. If my PQR is as per ASME SEC IX and if the hardness test is done, on what basis the test results are acceptable. 

Also please explain the same condition if we are qualifying dissimilar metals

Thanks and Regards

Hardness acceptance based on client specification / NACE  applicable also for 

dissimilar metals
