Fat and oil derivatives - Fatty Acid Methyl Esters (FAME) - Determination of ester and linolenic acid methyl ester contents

The purpose of this European Standard is to determine the ester content of fatty acid methyl esters (FAME) intended for use as pure biofuel or as a blending component for heating and diesel fuels. It also allows to determine the linolenic acid methyl ester content.
It allows one to verify that the ester content of FAME is greater than 90 % by mass (m/m) and that the linolenic acid content is between 1 % and 15 %.
This method is suitable for FAME which contain methyl esters between C14 and C24.

Erzeugnisse aus pflanzlichen und tierischen Fetten und Ölen - Fettsäure-Methylester (FAME) - Bestimmung des Ester-Gehaltes und des Gehaltes an Linolensäure-Methylester

Der Zweck dieser Europäischen Norm ist die Bestimmung des Estergehaltes von Fettsäure-Methylester (FAME), der als reiner Dieselkraftstoff oder als Blendkomponente für Heizöl oder Dieselkraftstoff Verwendung findet. Darüber hinaus ermöglicht die Norm auch, den Gehalt von Linolensäuremethylester zu bestimmen.
Das Prüfverfahren dient der Feststellung, ob der Ester-Gehalt in Pflanzenöl-Methylester größer als 90 % (m/m) ist und ob der Linolensäuregehalt zwischen 1 % (m/m) und 15 % (m/m) liegt.
Dieses Verfahren ist für FAME aus Methylestern mit einer Kettenlänge von C14 bis C24 anwendbar.

Produits dérivés des corps gras - Esters méthyliques d'acides gras (EMAG) - Détermination de la teneur en ester et en ester méthylique de l'acide linolénique

Cette Norme européenne a pour objet la détermination de la teneur en ester des esters méthyliques d'acides gras (EMAG) destinés a etre utilisés comme biocombustibles purs ou comme composant d'un combustible de chauffage et de carburant diesel. Elle permet également la détermination de la teneur en ester méthylique de l'acide linolénique.
Elle permet de vérifier que la teneur en ester des EMAG est supérieure a 90 % en masse (m/m) et que la teneur en acide linolénique est comprise entre 1 % et 15 %.
La présente méthode est applicable aux EMAG dont les esters méthyliques sont compris entre C14 et C24.
