Designation:D827420aStandard Test Method forDetermination of Biodiesel(Fatty Acid Methyl Esters)Content in Diesel Fuel Oil by Portable Rapid Mid-InfraredAnalyzer1This standard is issued under the fixed designation D8274;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.Scope*1.1 This test method covers the determination of the contentof biodiesel(fatty acid methyl esters(FAME)in diesel fueloils for volume fractions of 0.1%to 31.0%by mid-infraredanalyzer with a resolution of 0.1%.NOTE1ASTM and ISO specification fuels falling within the scope ofthis test method include Specifications:D975 grades No.1D and No.2D,D7467,distillate grades of D396,MIL-DTL-16884,and distillate gradesof marine fuel specification ISO 8217.1.2 The accuracy of this test method is based on themolecular weight of C16 and C18 FAME species.1.2.1 DiscussionBiodiesel contains a variety of specieswith different molecular weights.Typical market FAMEs fromNorth America and Europe,which are predominantly soy,rapeseed,and used cooking oil derived FAME were included inthe pilot study.FAME derived from coconut,which predomi-nantly 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 6.1.4 This test method has interim repeatability precisiononly,see Section 14 for more information.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 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.1.7 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:2D86 Test Method for Distillation of Petroleum Products andLiquid Fuels at Atmospheric PressureD396 Specification for Fuel OilsD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D975 Specification for Diesel FuelD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD4307 Practice for Preparation of Liquid Blends for Use asAnalytical StandardsD6299 Practice for Applying Statistical Quality Assuranceand Control Charting Techniques to Evaluate AnalyticalMeasurement System PerformanceD6300 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 FuelsD7371 Test Method for Determination of Biodiesel(FattyAcid Methyl Esters)Content in Diesel Fuel Oil Using Mid1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.04.0F on Absorption Spectroscopic Methods.Current edition approved Oct.1,2020.Published October 2020.Originallyapproved in 2019.Last previous edition approved in 2020 as D8274 20.DOI:10.1520/D8274-20A.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.*A Summary of Changes section appears at the end of this standardCopyright 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.Infrared Spectroscopy(FTIR-ATR-PLS Method)D7467 Specification for Diesel Fuel Oil,Biodiesel Blend(B6 to B20)D7797 Test Method for Determination of the Fatty AcidMethyl Esters Content of Aviation Turbine Fuel UsingFlo
