Liquid petroleum products - Determination of fatty acid methyl ester (FAME) content in middle distillates - Infrared spectrometry method

This European Standard specifies a test method for the determination of Fatty Acid Methyl Ester (FAME) content in diesel fuel or domestic heating fuel by mid infrared spectrometry, which applies to FAME contents of the two measurement ranges as follows:
-  range A: for FAME contents ranging from approx. 0,05 % (V/V) to approx. 3 % (V/V);
-  range B: for FAME contents ranging from approx. 3 % (V/V) to approx. 20 % (V/V);
-  range C: for FAME contents ranging from approx. 20 % (V/V) to approx. 50 % (V/V).
Principally, higher FAME contents can also be analyzed if diluted; however, no precision data for results outside the specified range is available at present.
This test method was verified to be applicable to samples which contain FAME conforming to EN 14214 or EN 14213. Reliable quantitative results are obtained only if the samples do not contain any significant amounts of other interfering components, especially esters and other carbonyl compounds which possess absorption bands in the spectral region used for quantification of FAME. If such interfering components are present, this test method is expected to produce higher values.
NOTE 1   For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction () of a material.
NOTE 2   For conversion of grams FAME per litre (g FAME/l) to volume fraction, a fixed density for FAME of 883,0 kg/m³ is adopted.
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 European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Flüssige Mineralölerzeugnisse - Bestimmung des Gehaltes an Fettsäuremethylester (FAME) in Mitteldestillaten - Infrarotspektrometrisches Verfahren

Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung des Gehaltes an Fettsäuremethylestern (FAME, en: Fatty Acid Methyl Esters) in Dieselkraftstoff oder Heizöl mit Hilfe der Infrarotspektrometrie im mittleren Infrarotbereich fest, und zwar für FAME-Gehalte in den drei folgenden Messbereichen:
   Messbereich A:   für FAME Gehalte von etwa 0,05 % (V/V) bis etwa 3 % (V/V);
   Messbereich B:   für FAME Gehalte von etwa 3 % (V/V) bis etwa 20 % (V/V);
   Messbereich C:   für FAME-Gehalte von etwa 20 % (V/V) bis etwa 50 % (V/V).
Höhere FAME-Gehalte können vom Grundsatz her ebenfalls nach entsprechender Verdünnung analysiert werden, jedoch enthält diese Norm gegenwärtig keine Präzisionsangaben für nicht in den genannten Messbereichen liegende Ergebnisse.
Das Prüfverfahren ist anwendbar auf Proben, deren FAME-Anteil die Anforderungsnormen EN 14214 erfüllt. Zuverlässige Ergebnisse können nur dann erhalten werden, wenn die Proben keine signifikanten Anteile an anderen störenden Komponenten enthalten, insbesondere Ester und andere Carbonylverbindungen, die ebenfalls starke Absorptions¬banden im für die FAME-Bestimmung benutzten Spektralbereich aufweisen. Wenn solche Störkomponenten vorhanden sind, wird dieses Prüfverfahren erwartungsgemäß zu hohe FAME Gehalte ausweisen.
ANMERKUNG 1   Für die Zwecke dieses Dokuments wird zur Angabe des Volumenanteils () einer Substanz der Ausdruck „% (VV)“ verwendet.
ANMERKUNG 2   Für die Umrechnung des FAME-Gehaltes von g FAME je Liter (g FAME/l) in „% (VV)“ wird eine mittlere feste Dichte für FAME von 883,0 kg/m3 verwendet.

Produits pétroliers liquides - Détermination de la teneur en esters méthyliques d'acides gras (EMAG) des distillats moyens - Méthode par spectrométrie infrarouge

Cette Norme européenne spécifie une méthode d'essai pour la détermination de la teneur en esters méthyliques d'acides gras (EMAG) dans le carburant pour moteurs diesel ou le fioul domestique, par spectrométrie dans l'infrarouge moyen. Cette méthode est applicable pour déterminer des teneurs en EMAG comprises dans l’un des deux intervalles de concentrations suivants :
   Intervalle A : pour des teneurs en EMAG comprises entre environ 0,05 % (V/V) et environ 3 % (V/V) ;
   Intervalle B : pour des teneurs en EMAG comprises entre environ 3 % (V/V) et environ 20 % (V/V).
   Intervalle C : pour des teneurs en EMAG comprises entre environ 20 % (V/V) et environ 50 % (V/V).
En principe, des teneurs en EMAG supérieures peuvent aussi être déterminées par une dilution préalable ; par contre, les données de fidélité ne sont pas disponibles actuellement en dehors des gammes de concentrations mentionnées.
Il a été vérifié que la méthode était applicable à des échantillons contenant des EMAG conformes aux spécifications européennes EN 14214 ou EN 14213 [1]. Des résultats quantitatifs fiables sont obtenus seulement lorsque les échantillons ne contiennent pas d’autres constituants interférant en quantités significatives, en particulier les esters et autres composés carbonylés, qui présentent des bandes d’absorption dans la région spectrale utilisée pour la quantification des EMAG. Lorsque de tels constituants sont présents, cette méthode d’essai donne des valeurs surestimées.
NOTE 1 Pour les besoins de la présente Norme européenne, l'expression «% (V/V)» est utilisée pour représenter la fraction volumique () d'un produit.
NOTE 2 Pour la conversion de grammes d’EMAG par litre (g d’EMAG / l) en fraction volumique, une masse volumique donnée d’EMAG de 883,0 kg/m3 est adoptée.
AVERTISSEMENT — L'utilisation de la présente Norme européenne peut impliquer l'intervention de produits, d'opérations et d'équipements à caractère dangereux. La présente norme européenne n'est pas censée aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité de l'utilisateur de consulter et d'établir des règles de sécurité et d'hygiène appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.

Tekoči naftni proizvodi - Določevanje metilnih estrov maščobnih kislin (FAME) v srednjih destilatih - Metoda infrardeče spektroskopije

Standard EN 14078 opredeljuje preskusno metodo za določanje vsebnosti metilnih estrov maščobnih kislin (FAME) v dizelskem gorivu ali gorivih za ogrevanje v gospodinjstvih z metodo srednje infrardeče spektroskopije, ki se nanaša na vsebnost metilnih estrov maščobnih kislin dveh razponov merjenja: - razpon A: za vsebnost metilnih estrov maščobnih kislin v razponu od pribl. 0,05 % (V/V) do pribl. 3 % (V/V); - razpon B: za vsebnost metilnih estrov maščobnih kislin v razponu od pribl. 3 % (V/V) do pribl. 20 % (V/V); - razpon C: za vsebnost metilnih estrov maščobnih kislin od pribl. 20 % (V/V) do pribl. 50 % (V/V). Načeloma je možno analizirati tudi višje vsebnosti metilnih estrov maščobnih kislin, če so razredčene; vendar pa trenutno ni na voljo natančnih podatkov za rezultate izven opredeljenega razpona. Ta preskusna metoda je bila potrjena, da se lahko uporablja za vzorce, ki vsebujejo metilne estre maščobnih kislin, v skladu z EN 14214 ali EN 14213. Zanesljive kvantitativne rezultate je mogoče dobiti le, če vzorci ne vsebujejo znatnih količin drugih motečih sestavin, zlasti estrov in drugih karbonilnih spojin, ki imajo absorpcijske pasove v spektralnem območju, ki se uporablja za količinsko določitev metilnih estrov maščobnih kislin. Če so take moteče snovi prisotne, se pričakuje, da bodo vrednosti, pridobljene s to preskusno metodo, višje.

The article discusses the European Standard EN 14078:2014, which outlines a method for determining the Fatty Acid Methyl Ester (FAME) content in diesel fuel or domestic heating fuel using mid infrared spectrometry. The method is applicable for FAME contents within specific measurement ranges, and higher FAME contents can be analyzed if diluted. However, there is no precision data available for results outside of the specified range. The test method is verified for samples containing FAME conforming to EN 14214 or EN 14213, and accurate results can only be obtained if there are no significant interfering components present. The article also provides notes on the use of "% (V/V)" to represent volume fraction and the conversion of grams FAME per liter to volume fraction. It emphasizes that the use of this European Standard may involve hazardous materials, operations, and equipment, so it is important for users to establish appropriate safety measures and consider regulatory limitations.
