What is BS EN 16300 - Determination of Iodine value FAME in automotive fuels about?
FAME is a type of biofuel produced from vegetable oils, animal fats, or waste cooking oils by a process called transesterification. BS EN 16300 discusses automotive fuels for the determination of iodine value in fatty acid methyl esters (FAME) to improve the quality of fat and oil derivatives.
BS EN 16300 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 or as an extender for automotive fuel for diesel engines as specified in EN 590.
This procedure has originally been described in Annex B of EN 14214:2008. 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 recognize 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.
Note 2: For the purposes of BS EN 16300, the term “% (m/m)” is used to represent the mass fraction, μ, of a material.
Who is BS EN 16300 - Determination of Iodine value FAME in automotive fuels for?
BS EN 16300 on the determination of Iodine value FAME in automotive fuels is useful for:
- Biodiesel industry
- Food technologists/ Scientists
- Biochemical engineers
- Automotive industry
- FAME component manufacturers
- Food laboratories
- Food health and safety departments
Why should you use BS EN 16300 - Determination of Iodine value FAME in automotive fuels?
The iodine value (IV) indicates the degree of unsaturation of a fat or oil. It is defined as the number of grams of iodine absorbed by 100 g of FAME.
For informative purposes only, but not for cases of dispute, EN 14331 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 BS EN 16300.
In principle, other fatty acid alkyl esters can also be analyzed. 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 the application range.
BS EN 16300 helps in determining the mass percentage of total methyl esters of fatty acids and the mass percentage of linolenic acid methyl ester present in the sample, by gas chromatography according to a procedure using internal calibration (nonadecanoic acid methyl ester).
With obedience and compliance to BS EN 16300, you can enhance fat and oil derivatives’ effectiveness and efficacy, create new products, and launch them successfully in a global market.
