Question
(OP)
Hi Good Morning. A client requested that our technicians test and certify one of their valves (new valve), however, while reviewing the Report, I noticed the following;
Original Nameplate Data: Valve: AG Crosby, Set Pressure 100-PSI, Capacity 91-SCFM, CDTP --; Note; No repairs or disassembly of the valve was done as it was a test only. The final record of testing showed that the set pressure was at 129 PSI and No Capacity change, Test Fluid was Nitrogen.
Is this acceptable and within the required codes and standards?

Read the Codes and make your own mind up whether it meets the Code requirements!!

129 vs 100 looks rather high to me - depending on the type of valve the vendor normally guarantees -10% + 5% as a worst case.
I think you might want to look at previous questions or ask this question in the safety relief valve forum.
PS - It's normal protocol on these forums to be a bit more descriptive in your post title and not something like "Question" or "help", but more like "Test vs set pressure of relief valve"
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Just what I was getting at with my response.
