Annotation

This European Standard specifies a gas chromatographic method for the quantitative determination, in unleaded petrol having a final boiling point not greater than 220 °C, of individual organic oxygenate compounds in the range 0,17 % (m/m) to 15 % (m/m) in a direct analysis (without dilution), and total organically bound oxygen up to 3,9 % (m/m).
For samples for which one of the oxygenate compounds content is higher than 15 % (m/m), a procedure with a dilution of the sample before the analysis is given.
NOTE 1 - The conversion from percent mass to percent volume is done using the calculation mentioned in 8.3 and 9.5.3.
NOTE 2 - Precision data are not available for an oxygenate compound content higher than 15 % (m/m); see Introduction.
NOTE 3 - For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction, respectively the volume fractio
