ÖNORM EN 16270

This European Standard specifies 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 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).
