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 total oxygenate content can be determined. This International Standard is applicable to automotive motor gasoline with a total content of aromatics of up to 50 % (V/V); a total olefin content from about 1,5 % (V/V) up to 30 % (V/V); oxygenate compounds, from 0,8 % (V/V) up to 15 % (V/V); a total oxygen content from about 1,5 % (m/m) to about 3 % (m/m); and a benzene content of up to 2 % (V/V). NOTE 1 For the purposes of this document, the terms“% (m/m)” and “% (V/V)” are used the represent, respectively, the mass fraction and the volume fraction. NOTE 2 While developing this method, the final boiling point was limited to 215 °C.
