Defines a determination method of high boiling components in petrol according to EN 228 and ethanol (E85) automotive fuels according to CEN/TS 15293 by capillary gas chromatography using flame ionization detection.

This European Standard specifies a determination method of high boiling components in petrol according to EN 228 [1] and ethanol (E85) automotive fuels according to CEN/TS 15293 [2] by capillary gas chromatography using flame ionization detection. This method is applicable to high boiling material, such as fatty acid methyl ester (FAME) or diesel fuel, having a boiling point greater than or equal to 1-methyl- naphthalene.

This European Standard is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature and covers a boiling range of at least 100 °C. This method pays special attention to fatty acid methyl esters.

In petrol the measurement range for the high boiling fraction is from about 0,7 % (m/m) to about 2,5 % (m/m). For the FAME fraction the range is from about 0,2 % (m/m) to about 2 % (m/m).

In ethanol (E85) automotive fuel the measurement range for the high boiling fraction is from about 0,2 % (m/m) to about 2,2 % (m/m), for the FAME fraction the range is from about 0,05 % (m/m) to about 1,5 % (m/m)

NOTE 1 When calculating the FAME fraction, this method only takes the C18 FAME compounds into account.

NOTE 2 For the purposes of this European Standard, the terms “% (m/m)?? and “% (V/V)?? are used to represent respectively the mass fraction and the volume fraction.

WARNING The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
