Designation:D829020An American National StandardStandard Test Method forDetermination of Fatty Acid Methyl Esters(FAME)inAviation Turbine Fuel using Mid-Infrared LaserSpectroscopy1This standard is issued under the fixed designation D8290;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the quantification of the fattyacid methyl esters(FAME)content in aviation turbine fuel inthe range of 10 mgkg to 400 mg kg by measuring infrared(IR)transmission before,during,and after FAME is convertedto molecules that absorb in a different spectral region thanFAME using a selective chemical reaction facilitated by asuitable catalyst.NOTE1This test method detects all FAME components with peak IRabsorbance at approximately 1749 cm-1and C8to C22carbon chain length.The accuracy of this test method is based on the molecular weight of C16to C18FAME species.The presence of other FAME species with differentmolecular weights could affect the accuracy.NOTE2Additives such as antistatic agents,antioxidants,and corro-sion inhibitors are measured with the FAME by mid IR absorption.However,these additives do not contribute to the differential absorptionspectrum used to quantify FAME,as they do not take part in the selectivereaction.1.2 This test method has interim repeatability precisiononly,see Section 15 for more information.1.3 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.Specific warning statements are given in Section 8.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD1655 Specification for Aviation Turbine FuelsD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD6300 Practice for Determination of Precision and BiasData for Use in Test Methods for Petroleum Products,Liquid Fuels,and LubricantsD6751 Specification for Biodiesel Fuel Blend Stock(B100)for Middle Distillate Fuels2.2 CEN Standard:3EN 14214 Liquid petroleum products Fatty acid methylesters(FAME)for use in diesel engines and heatingapplications Requirements and test methods3.Terminology3.1 Definitions:3.1.1 fatty acid methyl esters(FAME),na biodiesel com-posed of long chain fatty acid methyl esters derived fromvegetable or animal fats.3.1.1.1 DiscussionUsed as a component in diesel fuel andfuel oils,it is a potential source of contamination in aviationturbine fuel because of multi-fuel tankers and pipelines.3.1.2 identified incidental materials,nchemicals and com-positions that have defined upper content limits in an aviationfuel specification but are not approved additives.1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.J0.05 on Fuel Cleanliness.Current edition approved Nov.1,2020.Published December 2020.DOI:10.1520/D8290-20.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from European Committee for Standardization(CEN),AvenueMarnix 17,B-1000,Brussels,Belgium,http:/www.cen.eu.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.3.2 Definitions of Terms Specific to This Standard:3.2.1 column,nmulti-use column through which the testspecimen flows containing a suitable catalyst that facilitates theselective conversion of FAME to molecules that
