Significance and Use
5.1 Biodiesel is a fuel commodity primarily used as a blending component with diesel fuel. It is important to check the concentration of biodiesel in the diesel fuel in order to verify it is within limits or does not exceed the maximum allowable limit.
5.2 This test method is applicable for quality control in the production and distribution of diesel fuel and biodiesel blends.
5.3 This test is simple to run, completed in less than one minute, with no dilution of the test sample, no cleaning solvents are required, and the analyzer is portable and self-contained.
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 0.1 % to 31.0 % by mid-infrared analyzer with a resolution of 0.1 %.
Note 1: ASTM and ISO specification fuels falling within the scope of this test method include Specifications: grades No. 1D and No. 2D, , distillate grades of , MIL-DTL-16884, and 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.
1.2.1 Discussion—Biodiesel contains a variety of species with different molecular weights. Typical market FAMEs from North America and Europe, which are predominantly soy, rapeseed, and used cooking oil derived FAME were included in the pilot study. FAME derived from coconut, which predominantly contains C12, will over-read by approximately 30 %.
1.3 This method cannot distinguish between vegetable oils, animal fats, FAEE, compounds containing carbonyl groups, and FAME. For more information, see Section .
1.4 This test method has interim repeatability precision only, see Section for more information.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
