Gents, It is generally understood that PMI result reliability is as low as +/- 15%. It is mostly what can be called as go/no go type of test. Can any one confirm if ASME accepts PMI (by XRF) / Spectrometry and under what conditions.

Dear Mr.Binoy, Not necessary , it depends on project spec. and how confident in working system. For me , we will perform PMI internally anyway to double check correct material grade and correct welding rod. Be aware that some PMI spec. require to check Carbon on high or low carbon stainless such as 316L or 347H , etc. Normal PMI cannot perform this check and you have to use portable spectrometer which will be much more costly. You have to review PMI spec. and material you are welding carefully.
