Petroleum products and fat and oil derivates - Fatty acid methyl esters (FAME) for diesel engines - Determination of polyunsaturated (≥ 4 double bonds) fatty acid methyl esters (PUFA) by gas chromatography

This European Standard specifies a method for the determination of the polyunsaturated (≥ 4 double bonds) fatty acid (PUFA) methyl esters content of fatty acid methyl ester (FAME) as a whole between 0,6 % (m/m) and 1,5 % (m/m). The method covers the predominant four polyunsaturated fatty acid methyl esters of eicosatetraenoic acid (C 20:4 (n-6)), eicosapentaenoic acid (C 20:5 (n-3)), docosapentaenoic acid (C 22:5 (n-3), and docosahexaenoic acid (C 22:6 (n-3)). Studies have indicated that based on the linearity of results from this European Standard, PUFA methyl esters can be determined in FAME in the range between 0,3 % (m/m) to 3,0 % (m/m). However, the precision was not established in that range, as no samples within the upper ranges where included in the final interlaboratory test (see 10.1). Although the method is applicable to all uses, it is predominantly for FAME for use in diesel engines.

Mineralölerzeugnisse und Erzeugnisse aus pflanzlichen und tierischen Fetten und Ölen - Fettsäuremethylester (FAME) für Dieselmotoren - Bestimmung von mehrfach ungesättigten (≥ 4 Doppelbindungen) Fettsäuremethylestern (PUFA) mittels Gaschromatografie

Diese Europäische Norm legt ein Prüfverfahren für die Bestimmung des Gehaltes an mehrfach ungesättigten
(≥ 4 Doppelbindungen) Fettsäuremethylestern (en: polyunsaturated fatty acid methyl ester, PUFA methyl
ester) in Fettsäuremethylester (FAME) im Bereich von 0,6 % (m/m) bis 1,5 % (m/m) fest.
Das Prüfverfahren umfasst die Bestimmung der vier vorherrschenden mehrfach ungesättigten Fettsäuremethylester
Eicosatetraensäure (C 20:4 (n-6)), Eicosapentaensäure (C 20:5 (n-3)), Docosapentaensäure
(C 22:5 (n-3)) und Docosahexaensäure (C 22:6 (n-3)).
Studien haben gezeigt, dass basierend auf der Linearität von Ergebnissen nach dieser Europäischen Norm,
PUFA-Methylester in FAME in einem Bereich von 0,3 % (m/m) bis 3,0 % (m/m) bestimmt werden können. Da
im abschließenden Ringversuch keine Proben aus dem oberen Konzentrationsbereich einbezogen worden
waren, ist die Präzision für diesen Bereich nicht bestimmt worden (siehe 10.1).
Obwohl dieses Prüfverfahren allgemein eingesetzt werden kann, gilt es hauptsächlich für die Untersuchung
von FAME für den Einsatz in Dieselmotoren.
ANMERKUNG 1 Für die Zwecke dieses Dokuments wird das Symbol % (m/m) verwendet, um Massenanteile von
Materialien in % auszudrücken.
ANMERKUNG 2 Diese Europäische Norm wurde auf der Basis von A.O.C.S. Official Method Ce 1b-98 [1] erstellt.

Produits pétroliers et produits dérivés des corps gras - Esters méthyliques d'acides gras (EMAG) pour moteurs diesel (gazole) - Détermination de la teneur en esters méthyliques d'acides gras polyinsaturés (≥ 4 doubles liaisons) (PUFA) par chromatographie en phase gazeuse

La présente Norme européenne prescrit une méthode pour déterminer la teneur en esters méthyliques
d'acides gras polyinsaturés (≥4 doubles liaisons) (PUFA) des esters méthyliques d'acides gras (EMAG) en
totalité, entre 0,6 % (m/m) et 1,5 % (m/m).
La méthode couvre les quatre principaux esters méthyliques d'acides gras polyinsaturés des acides
éicosatétraénoïque (C 20:4 (n-6)), éicosapentaénoïque (C 20:5 (n-3)), docosapentaénoïque (C 22:5 (n-3)) et
docosahexaénoïque (C 22:6 (n-3)).
Les études ont montré, à partir de la linéarité des résultats obtenus suivant la présente Norme européenne,
que la teneur en esters méthyliques des PUFA peut être déterminée dans les EMAG quand celle-ci est
comprise entre 0,3 % (m/m) et 3,0 % (m/m). Cependant, les valeurs de fidélité n’ont pas été établies dans ce
domaine, étant donné qu’il n’y avait aucun échantillon dans la fourchette supérieure lors du dernier essai
interlaboratoires (voir 10.1).
Bien que cette méthode soit valable pour toutes les applications, elle est principalement destinée aux EMAG
utilisés dans les moteurs diesel.
NOTE 1 Pour les besoins de ce document, le terme « % (m/m) » est utilisé pour représenter la fraction massique des
produits.
NOTE 2 La présente Norme européenne est basée sur la Méthode Officielle A.O.C.S Ce 1b-89 [1].

EN 15779:2009 (E) 4 Introduction Polyunsaturated fatty acid methyl esters are considered as a critical component in FAME since they show a low stability against oxidation and polymerization reactions. The specification on polyunsaturated ester content is needed in FAME and biodiesel products to limit the content of polyunsaturated FAME with more than three double bonds. At the time of the first FAME fuel specifications no test method was available for such a complicated determination in terms of identification and quantification, so technical work has been done in a joint working group with CEN/TC 307 before any standardisation steps could be taken. The method has been prepared by the partners of the project "BIOScopes" (Lot 1, Task a) funded by the European Commission, DG TREN, with the purpose to execute a Pan-European round robin test to determine the precision data and the usability of this new and other revised determination methods for FAME.
