DIN EN 16300:2012-11

This document (EN 16300:2012) has been prepared by Technical Committee CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin"´, the secretariat of which is held by NEN (Netherlands). Regarding the German collaboration, the responsible committee is NA 062-06-32-01 UA "Prüfung von FAME" ("Testing of FAME") at the Petroleum, Fuels, Lubricants and Related Products Standardization Committee (FAM) of the Materials Testing Standards Committee (NMP). This European Standard 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. This calculation procedure is now specified for methyl esters between C14 and C24. The calculation procedure uses as data entry the results from the GC determination according to EN 14103 of individual fatty acid methyl esters; the calculation 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 recognise that the latest version of EN 14103 is to be used for the determination of individual FAME components. In principle, other fatty acid alkyl esters can also be analysed. 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 application range.
