There appears to be some conflict in the interpretation of testing for USP Medical Air:
Specifically, under 5.1.3.6.1(2) we are required to assure medical air complies with USP, which monograph includes Oxides of nitrogen and Sulfur dioxide.
However, under 5.1.12.4.12.3 and the Table, these two are missing.
In a verification, how many are in fact including these two?
