Methods of testing petroleum and associated products Standard test method for the identification of ...
This test method is a standard procedure for the determination of paraffins, olefins, naphthenes, aromatics
and unknowns (P.O.N.A.U.) in automotive gasolines using gas chromatography and flame ionization detection
(GC/FID). Individual hydrocarbon components greater than or equal to 0.01 % by mass are determined. Group types
greater than or equal to 0.01 % by mass are determined by summing…
