Liquid petroleum products. Determination of fatty acid methyl ester (FAME) content in middle distillates. Infrared spectrometry method Ingestion-build-239834 BS 1647-1 is the first1 Scope This European Standard specifies a test method for the determination of 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 approx. 0,05 % (V V) to approx. 3 % (V V); range B: for FAME contents ranging from approx. 3 % (V V) to approx. 20 % (V V); range C: for FAME contents
