ASTM D 8274 : 2020 : REV A

1.1This 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 %.

1.2The accuracy of this test method is based on the molecular weight of C16 and C18 FAME species.

1.3This method cannot distinguish between vegetable oils, animal fats, FAEE, compounds containing carbonyl groups, and FAME. For more information, see Section 6.

1.4This test method has interim repeatability precision only, see Section 14 for more information.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This 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.

1.7This 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.
