BS EN 14331:2004 PDF

1 Scope This European Standard specifies a method for the separation of fatty acid methyl esters (FAME) from middle distillates by liquid chromatography (LC) and for quantitative determination of the individual esters by gas chromatography (GC). This method is applicable to FAME of vegetable or animal origin that contain methyl esters between C 14 to C 24 . These FAME are mainly composed of C 16 - C 18 esters from fatty acids. This method is applicable whatever the origin of the middle distillate. This test method has been evaluated for the separation and characterisation of FAME present at up to 5 %  (V/V) in middle distillate. NOTE     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.
