EN 14214 Automotive Fuels - Fatty Acid Methyl Esters (FAME) for Diesel Engines - Requirements and Test Methods

EUROLAB laboratory provides testing and compliance services within the scope of EN 14214 standard. The EN 14214 standard specifies requirements and test methods for marketed and delivered fatty acid methyl esters (hereinafter FAME) to be used as fuel for diesel engines and for heating applications at 100% concentration or as an extender for distillate fuel for diesel engines.

In accordance with EN 590 requirements and for fuel heating. Applies to fuel at 100% concentration, for use in diesel engines and heating applications designed or retrofitted to operate with 100% FAME.

For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent the mass fraction µ and the volume fraction φ, respectively.

This European Standard gives all relevant specifications, requirements and test methods for fatty acid methyl esters (FAME) which are currently known to be required to identify the product to be used as automotive diesel fuel and in heating applications.

Most of the test methods contained in this European Standard have been subjected to several interlaboratory tests to determine their applicability and precision with respect to different FAME sources. These FAMEs were produced from vegetable oils available on the market at the time, particularly rapeseed, palm, soybean and sunflower oil. This does not imply any restriction on feedstock for fats and oils for which FAME has been made to comply with this European Standard.

Regarding total contamination, an interlaboratory study with field samples following a study with artificial samples is pending and therefore the reproducibility and reproducibility of EN 12662 has not yet been fully established. For FAME, certainty is sought.

With respect to the cold temperature properties of diesel blends regarding the quality of FAME used as a blending component, strong indications of association with saturated mono-glycerides and sterile-glycosides are known. An intermediate solution for setting CFPP and cloud point constraints is included in this standard, as a test method to individually detect these components has not yet been developed. A study within CEN has shown that FAME complies with the current precision statements of EN 116 and EN 23015.

Although there are technical indications that the iodine value could be eliminated as an indicator of FAME stability, relaxation at this time would be premature. The stability assurances introduced by this revision are maintained until proven on the market and also avoid the use of unnecessarily high levels of antioxidant additives. Reducing the phosphorus limit, sodium and potassium limit is being investigated to meet the needs of state-of-the-art engines.
