Difference between types of spectrometry?
(OP)
Dear All,
We wanted to test chemical composition of one our carbon steel plates as per ASME Sec II Part A - SA-751, clause 9(test methods). I opted for E-403 spectrometric analysis of steel, but our AI rejected it and said to use E-212 Spectrographic analysis of steels (rod-to-rod technique). My questions are:
1. What is the technical difference between the two?
2. Why it is not allowed to use E-403? or what are the limitations of E-403?

it was fairly generic, it has been superseded by much more method specific specs.
I agree with MET that there is no specific call out as to which method you use, you simply must use a recognized analysis method.
