1.1 This test method determines fatty acid methyl esters (FAME) biodiesel in diesel fuel oils. FAME can be quantitatively determined from 0.50 to 30 volume %. This method is only applicable to FAME. This test method uses linear variable filter (LVF) array-based mid-infrared spectroscopy for monitoring FAME concentration. 1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The proposed test method will most likely be used by fuel regulators, refinery quality control personnel, and others that have a need for a portable analyzer for use in determining biodiesel blends.
