This European standard specifies a column switching gas chromatographic method for the quantitative determination of benzene content in the range 0,05 % (V/V) to 6 % (V/V) in unleaded petrol having a final boiling point not greater than 220 °C.
The method described in this standard is suitable for determining benzene in petrol, including petrol containing oxygenates, in line with the relevant EC Directives1).

NOTE For the purposes of this European Standard, the terms “% (V/V) and “% (m/m)” are used to represent respectively the volume fraction and the mass fraction.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
