This European Standard specifies a determination method of high boiling components in petrol according to EN 228 [1] by capillary gas chromatography using flame ionisation 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 a boiling range of at least 100 °C. This method pays special attention to fatty acid methyl esters.

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

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

NOTE 2 For the purposes of this standard, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction (μ) and the volume fraction (φ) of a material respectively.

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.
