Abstract

1 Scope This International Standard specifies the gas chromatographic (GC) method for the determination of saturated, olefinic and aromatic hydrocarbons in automotive motor gasoline and ethanol (E85) automotive fuel. Additionally, the benzene content, oxygenate compounds and the total oxygen content can be determined.

NOTE 1 For the purposes of this document, the terms % ( m/m ) and % ( V/V ) are used to represent respectively the mass fraction, µ , and the volume fraction, φ .

This International Standard defines two procedures, A and B. Procedure A is applicable to automotive motor gasoline with total aromatics of up to 50 % ( V/V ); total olefins from about 1,5 % ( V/V ) up to 30 % ( V/V ); oxygenates from 0,8 % ( V/V ) up to 15 % ( V/V ); total oxygen from about 1,5 % ( m/m ) to about 3,7 % ( m/m ); and benzene of up to 2 % ( V/V ). The system can be used for ethers with 5 or more C atoms up to 22 % ( V/V ) but the precision has not been established up to this level. 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 h...
