1.1 This test method covers the determination of the content of biodiesel [fatty acid methyl esters (FAME)] in diesel fuel oils for volume fractions of 0 to 40 %. NOTE 1-ASTM and ISO specification fuels falling within the scope of this test method include Specifications: D975 grades No. 1D and No. 2D, D7467, distillate grades of D396, and MIL-DTL-16884 distillate grades of marine fuel specification ISO 8217. 1.2 The accuracy of this test method is based on the molecular weight of C16 and C18 FAME species. 1.3 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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.

There are no portable handheld devices capable of doing this test in the field. Diesel now contains biodiesel in many territories to meet regulations. This test method gives a means to test on board a ship, or at a terminal.
