This International Standard specifies the gas chromatographic (GC) method for the determination of saturated, olefinic and aromatic hydrocarbons in automotive motor gasoline. Additionally, the benzene content, oxygenate compounds and the total oxygen content can be determined. This method defines two procedures, A and B. Procedure A is applicable to automotive motor gasoline with a total volume fraction of aromatics of up to 50 %; a total volume fraction of olefins from about 1,5 % up to 30 %; a volume fraction of oxygenates, from 0,8 % up to 15 %; a total mass fraction of oxygen from about 1,5 % to about 3.7 %; and a volume fraction of benzene of up to 2 %. Although this test method can be used to determine higher-olefin contents of up to 50% (V/V), the precision for olefins was tested only in the range from about 1,5 % (V/V) to about 30% (V/V). Although specifically developed for the analysis of automotive motor gasoline that contains oxygenates, this test method can also be applied to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.
