DIN EN 14078:2014-09

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 Petroleum, Fuels, Lubricants and Related Products Standardization Committee (FAM) of the Materials Testing Standards Committee (NMP) at DIN. This European Standard specifies a test method for the determination of the Fatty Acid Methyl Ester (FAME) content in diesel fuel or domestic heating fuel by mid infrared spectrometry, which applies to FAME contents of the three measurement ranges as follows: range A: for FAME contents ranging from approximately 0,05 % (V/V) to approximately 3 % (V/V); range B: for FAME contents ranging from approximately 3 % (V/V) to approximately 20 % (V/V); 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 accordingly; however, this standard does not provide any precision data for results outside the specified measurement ranges at present. This test method was verified to be applicable to samples which contain FAME conforming to the requirements standard EN 14214. Reliable results are obtainable only if the samples do not contain any significant amounts of other interfering components, especially esters and other carbonyl compounds with absorption bands in the spectral region used for quantification of FAME. If such interfering components are present, this test method is expected to produce exceedingly high values.
