NACE Vs ASTM Hardness values

[engineer2385]

Hello Everyone,
If a material(e.g.F22 after heat treatment)hardness falls within NACE requirements but outside ASTM requirements, what should govern accept/reject criteria?


Thanks

Pure logic:

If end user/project requires both: Reject
If ASTM only Reject
If NACE only OK

Note: Valid for any regulation or requirement: If something was OK before, but then is not OK anymore, then it is not OK until repaired or replaced !
