DIN EN 14078:2014-07

This document (EN 14078:2014) 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). The responsible German body is Working Subcommittee NA 062-06-32-01 UA "Prüfung von FAME" ("Testing of FAME") at the Standardization Committee for Petroleum, Fuels, Lubricants and Related Products (FAM) of the Materials Testing Standards Committee (NMP) at DIN. This European Standard specifies a test method for the determination of Fatty Acid Methyl Esters (FAME) content in diesel fuel or domestic heating fuel by infrared spectrometry in the mid-infrared range, which applies to FAME contents of the two measurement ranges as follows: a) measurement range A: for FAME contents ranging from approximately 0,05 % (V/V) to approximately 3 % (V/V); b) measurement range B: for FAME contents ranging from approximately 3 % (V/V) to approximately 20 % (V/V); c) measurement range C: for FAME contents ranging from approximately 20 % (V/V) to approximately 50 % (V/V). Principally, higher FAME contents can also be analysed if diluted; however, no precision data for results outside the specified range is available at present. The test method was verified to be applicable to samples which contain FAME conforming to EN 14214. 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.
