1.1 ,This test method determines fatty acid methyl esters (FAME or biodiesel) in diesel fuel oils. FAME can be quantitatively determined from 1.0 ,% to 30.0 ,% by volume. This test method uses linear variable filter (LVF) array based mid-infrared spectroscopy for monitoring FAME concentration.
Note 1: ,See Section 6 for a list of interferences that could affect the results produced from this method.
