(Main)Automotive fuels - Determination of iodine value in fatty acid methyl esters (FAME) - Calculation method from gas chromatographic data
Automotive fuels - Determination of iodine value in fatty acid methyl esters (FAME) - Calculation method from gas chromatographic data
This European Standard specifies a calculation procedure for the determination of Iodine value ("CIV" - "calculated iodine value"), of fatty acid methyl esters (FAME) to be used either as automotive or heating fuel for diesel engines as specified in EN 14214 [2] or as an extender for automotive fuel for diesel engines as specified in EN 590 [4].
This procedure has originally been described in Annex B of EN 14214:2008 [2]. The calculation procedure is now specified for methyl esters between C14 and C24. The calculation procedure uses as data entry the results from the gas chromatography determination (GC) according to EN 14103 of individual fatty acid methyl esters and is based on AOCS recommended practice Cd 1c – 85 for the determination of the iodine value of edible oil from its fatty acid composition. It is important to recognise that the latest version of EN 14103 is to be used for the determination of individual FAME components.
NOTE 1 Experience from the field and from several precision evaluation campaigns in Germany and elsewhere indicates that the results of the determination of iodine value by calculation specified here are very close to results obtained by titration with Wijs solvent according to EN 14111. Observed small differences were always found to be smaller than the reproducibility published in the actual EN 14111.
For informative purposes only, but not for cases of dispute, EN 14331 [5] may also be used to extract the FAME contents from FAME containing diesel fuels (like B5, B7, B30, etc.) and to use the contents of the individual FAME components from this method as data entry for the calculation specified in this European Standard.
In principle, other fatty acid alkyl esters can also be analysed. However, neither the close correlation to the titration method EN 14111 has been verified nor is any precision information available for such an extension of application range.
NOTE 2 For the purposes of this European Standard, the term "% (m/m)" is used to represent the mass fraction, µ, of a material.
Kraftstoffe für Kraftfahrzeuge - Bestimmung der Iodzahl in Fettsäure-Methylester (FAME) - Berechnung aus gaschromatographischen Daten
Dieses Dokument legt ein Berechnungsverfahren zur Bestimmung der Iodzahl ("CIV", en: calculated iodine value - "berechnete Iodzahl") von Fettsäure Methylestern (FAME, en: fatty acid methyl esters) fest, die entweder als Kraftstoff für Dieselmotoren nach EN 14214 [2], oder als Heizöl, oder als Blendkomponente für Kraftstoff für Dieselmotoren nach EN 590 [3] verwendet werden. Dieses Verfahren gilt nicht für Ethylester oder für aus Fischöl gewonnene Ester und Gemische daraus.
Das Berechnungsverfahren gilt für Methylester zwischen C6 und C24:1. Als Eingangsdaten für das Berechnungsverfahren dienen die Ergebnisse der Bestimmung mittels Gaschromatographie (GC) nach EN 14103 für die einzelnen Fettsäure Methylester. Die Berechnung beruht auf dem von der AOCS empfohlenen Verfahren Cd1c 85 zur Bestimmung der Iodzahl von Speiseöl aufgrund seiner Fettsäurezusammensetzung. Es ist wichtig zu beachten, dass die aktuelle Fassung der EN 14103 zur Bestimmung der einzelnen FAME Komponenten vorgesehen ist.
ANMERKUNG Erfahrungen aus der Praxis und aus der Auswertung mehrerer in Deutschland und anderen Ländern durchgeführter Ringversuche haben gezeigt, dass die Ergebnisse der Iodzahlbestimmung nach der hier festgelegten Berechnung sehr nahe bei den Ergebnissen liegen, die durch Titration mit Wijs Lösemittel nach EN 14111 [1] erhalten werden. Beobachtete geringe Unterschiede waren stets kleiner als die in der aktuellen EN 14111 angegebene Vergleichpräzision.
Nur für Informationszwecke, jedoch nicht in Streitfällen, darf EN 14331 [4] auch für die Extraktion der FAME Komponenten aus FAME haltigen Dieselkraftstoffen (wie B5, B7, B30 usw.) und zur Verwendung der Gehalte der einzelnen FAME Komponenten nach diesem Verfahren als Eingangsdaten für die in diesem Dokument festgelegte Berechnung angewendet werden.
Dieses Berechnungsverfahren kann nur dann angewendet werden, wenn die untersuchte Probe die Anforderung an den Estergehalt, wie in EN 14214 angegeben, erfüllt.
Die Präzisionsangabe dieses Prüfverfahrens wurde durch Berechnung im Rahmen einer Ringversuchaufgabe mit Iodzahlen in dem Bereich von 16 g Iod/100 g bis 126 g Iod/100 g bestimmt.
Das Prüfverfahren ist auch für höhere Iodzahlen anwendbar; die Präzisionsangabe wurde jedoch nicht für Iodzahlen oberhalb von 126 g Iod/100 g bestimmt.

1 Scope
This document specifies a calculation procedure for the determination of iodine value (“CIV” -
“calculated iodine value”), of fatty acid methyl esters (FAME) to be used either as automotive fuel for
diesel engines as specified in EN 14214 [2] or heating fuel or as an extender for automotive fuel for
diesel engines as specified in EN 590 [3]. Ethyl esters or esters made from fish oil and mixtures thereof
are not covered by this procedure.
The calculation procedure is specified for methyl esters between C6 and C24:1. The calculation
procedure uses as data entry the results from the gas chromatography determination (GC) according to
EN 14103 of individual fatty acid methyl esters and is based on AOCS recommended practice Cd 1c - 85
for the determination of the iodine value of edible oil from its fatty acid composition. It is important to
recognize that the latest version of EN 14103 is intended to be used for the determination of individual
FAME components.
NOTE Experience from the field and from several precision evaluation campaigns in Germany and elsewhere
indicates that the results of the determination of iodine value by the calculation specified here are very close to
results obtained by titration with Wijs solvent according to EN 14111 [1]. Observed small differences were always
found to be smaller than the reproducibility published in the actual EN 14111.
For informative purposes only, but not for cases of dispute, EN 14331 [4] may also be used to extract
the FAME contents from FAME containing diesel fuels (like B5, B7, B30, etc.) and to use the contents of
the individual FAME components from this method as data entry for the calculation specified in this
document.
This calculation method can be used only if the evaluated sample fulfils the requirement for ester
content as reported in EN 14214.
The precision statement of this test method was determined by calculation from a Round Robin
exercise with iodine values in the range of 16 g iodine/100 g to 126 g iodine/100 g.
