ASTM D 8290 : 2022

1.1This test method covers the quantification of the fatty acid methyl esters (FAME) content in aviation turbine fuel in the range of 10 mg/kg to 400 mg/kg by measuring infrared (IR) transmission before, during, and after FAME is converted to molecules that absorb in a different spectral region than FAME using a selective chemical reaction facilitated by a suitable catalyst.

1.2This test method has interim repeatability precision only, see Section 15 for more information.

1.3Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This 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. Specific warning statements are given in Section 8.

1.5This 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.
