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.

Goriva za motorna vozila - Določanje jodnega števila v metilnih estrih maščobnih kislin (FAME) - Računska metoda iz podatkov pridobljenih s plinsko kromatografijo

Ta evropski standard določa postopek izračuna za določanje jodnega števila (»CIV« – izračunano jodno število) v metilnih estrih maščobnih kislin (FAME), ki se uporabljajo kot gorivo za motorna vozila ali gorivo za ogrevanje za dizelske motorje, kot je določeno v standardu EN 14214 [2], ali kot aditiv za gorivo za motorna vozila za dizelske motorje, kot je določeno v standardu EN 590 [4].
Ta postopek je bil izvorno opisan v dodatku B k standardu EN 14214:2008 [2]. Postopek izračuna je zdaj določen za metilne estre med C14 in C24. Postopek izračuna kot podatkovne vnose uporablja rezultate plinske kromatografije (GC) v skladu s standardom EN 14103 posameznih metilnih estrov maščobnih kislin in temelji na priporočeni praksi AOCS Cd 1c – 85 za določanje jodnega števila v jedilnem olju iz njegove maščobno-kislinske sestave. Pomembno je poudariti, da je treba za ugotavljanje posameznih komponent metilnih estrov maščobnih kislin uporabiti najnovejšo različico standarda EN 14103.
OPOMBA 1:   Izkušnje s terena in izkušnje, pridobljene v številnih kampanjah za vrednotenje natančnosti v Nemčiji in drugod, kažejo, da so rezultati določanja jodnega števila z izračunom, navedeni v tem dokumentu, zelo blizu rezultatom, pridobljenim s titracijo z Wijsovim topilom v skladu s standardom EN 14111. Ugotovljene majhne razlike so bile vselej manjše od ponovljivosti, objavljene v dejanskem standardu EN 14111.
Standard EN 14331 [5] je mogoče – samo v informativne namene, vendar ne v primeru spora – uporabiti tudi za pridobivanje vsebnosti metilnih estrov maščobnih kislin (FAME) iz dizelskih goriv,ki vsebujejo metilne estre maščobnih kislin (npr. B5, B7, B30 itd.), in za uporabo vsebnosti posameznih komponent metilnih estrov maščobnih kislin iz te metode kot podatkovne vnose za izračun, določen v tem evropskem standardu.
Načeloma je mogoče analizirati tudi druge alkilne estre maščobnih kislin. Vendar tesna povezava s titracijsko metodo EN 14111 ni bila preverjena, niti niso na voljo informacije o natančnosti za tako razširitev področja uporabe.
OPOMBA 2:   V tem evropskem standardu se za predstavitev masnega deleža (µ) materiala uporablja izraz »% (m/m)«.
