La présente Norme internationale spécifie des méthodes de préparation des esters méthyliques d'acides gras.Elle comprend des méthodes de préparation des esters méthyliques d'acides gras à partir des corps gras d'origines animale et végétale, des acides gras et des savons. Afin de répondre à différentes exigences, trois méthodes de méthylation sont spécifiées, à savoir:a) la méthode au trifluorure de bore (BF3) (voir l'article 3);b) la méthode à l'hydroxyde de triméthylsulfonium (TMSH) (voir l'article 4);c) la méthode de transestérification (voir l'article 5).Les esters méthyliques ainsi obtenus peuvent être utilisés dans diverses méthodes d'analyse exigeant des produits dérivés de ce type, telles que la chromatographie en phase gazeuse (CPG), la chromatographie en couche mince (CCM) ou la spectrométrie à infrarouge (IR).
