Automotive fuels - Determination of high-boiling components including fatty acid methyl esters in petrol and ethanol (E85) automotive fuel - Gas chromatography method
This European Standard specifies a determination method of high boiling components in petrol and in ethanol (E85) automotive fuel. The method is based on capilary gas chromatography using flame ionisation detection. High boiling components, such as diesel or fatty acid methyl esters (FAME), are defined by those having a boiling point greater than or equal to 1-methyl-naphthalene.
This European Standard is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature and a boiling range of at least 100 °C. This method pays special attention to fatty acid methyl esters.
Kraftstoffe für Kraftfahrzeuge - Bestimmung von hochsiedenden Komponenten in Ottokraftstoff und Ethanol (E85)-Autokraftstoff - Gaschromatographisches Verfahren
Diese Europäische Norm legt ein Verfahren zur Bestimmung hochsiedender Komponenten in Ottokraftstoff nach EN 228 [1] und in Ethanol (E85)-Autokraftstoff nach CEN/TS 15293 [2] mittels Kapillar-Gaschromatographie mit Flammenionisationsdetektor fest. Dieses Verfahren ist anwendbar auf hochsiedende Substanzen wie Fettsäure-Methylester (FAME) oder Dieselkraftstoff, die einen Siedepunkt größer oder gleich 1-Methylnaphthalin besitzen.
Diese Norm ist anwendbar auf Stoffe mit einem Dampfdruck, der niedrig genug zur Probenahme bei Umgebungstemperatur ist, sowie einem Siedebereich von mindestens 100 °C. Dieses Verfahren berücksichtigt speziell Fettsäuremethylester.
Der Messbereich für den hochsiedenden Anteil ist in Ottokraftstoff von etwa 0,7 % (m/m) bis etwa 2,5 % (m/m). Für FAME ist der Bereich von etwa 0,2 % (m/m) bis etwa 2 % (m/m).
Der Messbereich für den hochsiedenden Anteil ist in Ethanol (E85) Autokraftstoff von etwa 0,2 % (m/m) bis etwa 2,2 % (m/m). Für FAME ist der Bereich von etwa 0,05 % (m/m) bis etwa 1,5 % (m/m).
ANMERKUNG 1 Für Berechnung des FAME Anteils werden im Rahmen dieses Verfahrens nur die C18-Isomere berücksichtigt.
ANMERKUNG 2 Für die Zwecke dieser Europäischen Norm wird zur Angabe des Massenanteils einer Substanz der Ausdruck „% (m/m)“ und für den Volumenanteil einer Substanz der Ausdruck „% (V/V)“ verwendet.
WARNUNG — Die Anwendung dieser Norm kann den Einsatz gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Europäische Norm gibt nicht vor, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Der Anwender dieser Norm ist dafür verantwortlich, vorher angemessene Maßnahmen in Hinblick auf Sicherheit und Gesundheit zu ergreifen und die Anwendbarkeit einschränkender Vorschriften zu ermitteln.

Ta evropski standard opredeljuje metodo določanja komponent z visokim vreliščem v motornem bencinu in etanolu (E85). Metoda temelji na metodi plinske kromatografije z uporabo z zaznavanjem plamenske ionizacije. Komponente z visokim vreliščem, kot so dizelsko gorivo ali metilni estri maščobnih kislin (FAME), so določeni s tistimi, ki imajo vrelišče višje ali enako kot 1-metil-naftalen. Ta evropski standard se uporablja za materiale, ki imajo dovolj nizek parni tlak, da je mogoče izvajati vzorčenje pri temperaturi okolice, in območje vrelišča najmanj 100 °C. Ta metoda posveča posebno pozornost metilnim estrom maščobnih kislin.

Foreword
This document (prEN 16270:2014) has been prepared by Technical Committee CEN/TC 19 “Gaseous and
liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the secretariat of
which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16270:2012. Its scope has been extended to ethanol (E85) automotive fuel,
the precision data have been updated and further technical improvements have been included.
1 Scope
This European Standard specifies a determination method of high boiling components in petrol according to
EN 228 [1] and ethanol automotive fuels according to CEN/TS 15293 [2] by capillary gas chromatography
using flame ionisation detection. This method is applicable to high boiling material, such as fatty acid methyl
ester (FAME) or diesel fuel, having a boiling point greater than or equal to 1-methyl-naphthalene.
The standard is applicable to materials having a vapour pressure low enough to permit sampling at ambient
temperature and a boiling range of at least 100 °C. This method pays special attention to fatty acid methyl
esters.
In petrol the measurement range for the high boiling fraction is from about 0,7 % (m/m) to about 2,5 % (m/m).
For the FAME fraction the range is from about 0,2 % (m/m) to about 2 % (m/m).
In ethanol automotive fuel the measurement range is from about 0,2 % (m/m) to about 2,2 % (m/m), for the
FAME fraction the range is from about 0,05 % (m/m) to about 1,5 % (m/m)
NOTE 1 When calculating the FAME fraction, this method only takes the C18-isomers into account
NOTE 2 For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent
respectively the mass fraction and the volume fraction.
