Automotive fuels - Determination of high-boiling components including fatty acid methyl esters in petrol and ethanol (E85) automotive fuel - Gas chromatographic method
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 ionization 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.
WARNING -The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

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.

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.
General Information

Overview
EN 16270:2015 - published by CEN - specifies a gas chromatographic method for the determination of high‑boiling components (including fatty acid methyl esters, FAME) in petrol (EN 228) and ethanol (E85) automotive fuel (CEN/TS 15293). The method uses capillary gas chromatography with a flame ionization detector (FID) and is applicable to high‑boiling materials with boiling points ≥ 1‑methyl‑naphthalene and a boiling range of at least 100 °C. The standard includes safety warnings and sampling guidance.
Key topics and technical requirements
- Analytical principle: separation by capillary GC with a linear temperature program; detection by FID; fraction limits established using a calibration mixture.
- Target fraction definitions:
- Total high‑boiling fraction: from 1‑methyl‑naphthalene up to and including dotriacontane (n‑C32).
- FAME (C18) fraction: cumulative area of C18:0, C18:1, C18:2 and C18:3 FAME peaks (note: only C18 isomers are used for FAME calculation).
- Measurement ranges:
- Petrol high‑boiling: ~0.7 % (m/m) to ~2.5 % (m/m). Petrol FAME: ~0.2 % to ~2 % (m/m).
- Ethanol (E85) high‑boiling: ~0.2 % to ~2.2 % (m/m). E85 FAME: ~0.05 % to ~1.5 % (m/m).
- Calibration: gravimetric calibration mixture typically containing 1‑methyl‑naphthalene, dotriacontane (C32) and a C18‑rich FAME in a solvent (e.g., n‑heptane). Users must calculate total calibration areas for high‑boiling and FAME fractions.
- Apparatus & conditions: capillary column (example: 10 m × 0.53 mm ID, dimethyl polysiloxane, df ≈ 0.88 µm), PTV or cool on‑column inlet, oven ramp capability to ~350 °C, and FID capable of the required temperatures. Carrier gas purity and cleanliness are emphasized.
- Sampling & safety: samples per EN ISO 3170 / EN ISO 3171; avoid plastic storage; follow safety precautions for flammable gases and solvents.
Applications and users
- Fuel quality control laboratories assessing petrol and E85 compliance.
- Automotive fuel producers monitoring contamination by high‑boiling materials (diesel, FAME).
- Regulatory and standards bodies enforcing fuel specifications.
- Analytical laboratories specializing in gas chromatography, FAME analysis, and petroleum product testing. Practical uses include verifying blend integrity, detecting carry‑over of diesel or biodiesel components into petrol/E85, and routine QC of incoming fuel batches.
