CEN/TC 307/WG 1 - Test methods on fatty acid methylester

This European Standard specifies a method for the determination of potassium contents equal to or greater than 0,5 mg/kg.
This method is applicable to fatty acid methyl esters intended for addition to mineral oils.
WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This European Standard specifies a gas chromatographic method for the determination of free glycerol content in Fatty Acid Methyl Esters (FAME) in the range of 0,005 % to 0,070 %, hereinafter referred as FAME.
This method aims to evaluate the FAME quality, in terms of transesterification by-products content such as glycerol, whose concentration may affect the fuel behaviour.
WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
NOTE   In the context of this method (m/m) and (v/v) can be used.

This European standard specifies a method for the determination of sodium contents equal to or greater than
1 mg/kg.
This method is applicable to fatty acid methyl esters intended for addition to mineral oils.
WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This European Standard specifies an inductively coupled plasma (ICP) emission spectrometry method for the determination of phosphorus content between 4 mg/kg and 20 mg/kg in Fatty Acid Methyl Esters, hereinafter referred as FAME.
This method aims to evaluate the FAME quality, in terms of transesterification by-products content such as phosphorus, whose concentration may affect the fuel behaviour.
WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This European Standard specifies a titrimetric method for the determination of iodine value in Fatty Acid Methyl Esters, hereinafter referred as FAME.

This European Standard specifies one titrimetric method for the determination of acid value in light coloured Fatty Acid Methyl Esters, hereinafter referred as FAME.
It allows the determination of acid value within a range of 0,10 mg KOH/g to 1,00 mg KOH/g.

This European Standard specifies a method for the determination of methanol content in fatty acid methyl esters (FAME) for use as diesel fuel and domestic heating fuel. The method is applicable for a concentration range from 0,01 % to 0,5 % (m/m) methanol. The method is not applicable to mixtures of FAME which contain other low boiling components.

This European Standard specifies a method for the determination of the oxidation stability of fatty acid methyl esters (FAME) at 110 °C.

This European Standard specifies a method to determine the free glycerol and residual mono-, di- and triglyceride contents in fatty acid methyl esters (FAME) intended for addition to mineral oils. The total glycerol content is then calculated from the results obtained.
This method is suitable for FAME from rapeseed, sunflower, soybean oils but is not suitable for FAME produced from or containing coconut and palm kernel oils because of overlapping of peaks.
WARNING - The use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The purpose of this European Standard is to determine the ester content of fatty acid methyl esters (FAME) intended for use as pure biofuel or as a blending component for heating and diesel fuels. It also allows to determine the linolenic acid methyl ester content.
It allows one to verify that the ester content of FAME is greater than 90 % by mass (m/m) and that the linolenic acid content is between 1 % and 15 %.
This method is suitable for FAME which contain methyl esters between C14 and C24.
