Designation:D843421An American National StandardStandard Specification forUnleaded Aviation Gasoline Test Fuel Containing Organo-metallic Additive1This standard is issued under the fixed designation D8434;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 specification covers formulating specifications forpurchases of an unleaded aviation gasoline test fuel undercontract and is intended solely for use by purchasing agenciesfor testing purposes.1.2 This specification defines a specific type of aviationgasoline for use as an aviation spark-ignition engine test fuel.It does not include all gasolines satisfactory for reciprocatingaviation engines.Certain equipment or conditions of use maypermit a wider,or require a narrower,range of characteristicsthan is shown by this specification.1.3 The unleaded aviation gasoline test fuel defined by thisspecification does exhibit similar octane performance to thoseleaded fuels with which the existing aircraft and ground-basedfuel handling equipment have been designed to operate.1.4 Issuance of this specification does not constitute ap-proval to operate certificated aircraft with this test fuel.Fuelsused in certified engines and aircraft are ultimately approvedby the certifying authority subsequent to formal submission ofevidence to the authority as part of a certification program.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 specification,unless otherwise provided,prescribesthe required properties of unleaded aviation gasoline test fuel atthe time and place of delivery.1.7 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.1.8 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 PressureD130 Test Method for Corrosiveness to Copper from Petro-leum Products by Copper Strip TestD323 Test Method for Vapor Pressure of Petroleum Products(Reid Method)D357 Method of Test for Knock Characteristics of MotorFuels Below 100 Octane Number by the Motor Method;Replaced by D 2700(Withdrawn 1969)3D381 Test Method for Gum Content in Fuels by Jet Evapo-rationD614 Method of Test for Knock Characteristics of AviationFuels by the Aviation Method;Replaced by D 2700(Withdrawn 1970)3D873 Test Method for Oxidation Stability of Aviation Fuels(Potential Residue Method)D909 Test Method for Supercharge Rating of Spark-IgnitionAviation GasolineD910 Specification for Leaded Aviation GasolinesD1094 Test Method for Water Reaction of Aviation FuelsD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD1948 Method of Test for Knock Characteristics of MotorFuels Above 100 Octane Number by the Motor Method;Replaced by D 2700(Withdrawn 1968)3D2386 Test Method for Freezing Point of Aviation FuelsD2392 Test Method for Color of Dyed Aviation GasolinesD2622 Test Method for Sulfur in Petroleum Products byWavelength Dispersive X-ray Fluorescence SpectrometryD2624 Test Methods for Electrical Conductivity of Aviationand Distillate Fuels1This specification is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.J0.02 on Aviation Piston Engine Fuels.Current edition approved Dec.1,2021.Published March 2022.DOI:10.1520/D8434-21.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.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.1D2700 Test Method for Motor Octane Number of
