Designation:D771921aAn American National StandardStandard Specification forHigh Aromatic Content Unleaded Hydrocarbon AviationGasoline Test Fuel1This standard is issued under the fixed designation D7719;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 specification covers formulating specifications forpurchases of a high aromatic content unleaded hydrocarbonaviation gasoline test fuel under contract and is intended solelyfor use by purchasing agencies for testing purposes.21.2 This specification defines a specific type of high aro-matic content unleaded hydrocarbon aviation gasoline(hereaf-ter also referred to as“D7719 fuel”)for use as an aviationspark-ignition test fuel.It does not include all fuels satisfactoryfor reciprocating aviation engines.Certain equipment or con-ditions of use may permit a wider,or require a narrower,rangeof characteristics than is shown by this specification.1.3 The D7719 fuel defined by this specification does notexhibit identical performance to those leaded fuels for whichthe existing aircraft and ground-based fuel handling equipmenthave been designed to operate on.Therefore,the suitability ofthis test fuel for use on any specific aircraft,aircraft engine,orground-based fuel handling equipment should be evaluatedbefore use on that equipment.1.4 Issuance of this specification does not constitute ap-proval to operate certificated aircraft with this fuel.Fuels usedin certified engines and aircraft are ultimately approved by thecertifying authority subsequent to formal submission of evi-dence to the authority as part of the certification program forthat aircraft and engine model.1.5 This specification,unless otherwise provided,prescribesthe required properties of unleaded D7719 test fuel at the timeand place of delivery.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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:3D86 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)D873 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 FuelsD1266 Test Method for Sulfur in Petroleum Products(LampMethod)D1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD2386 Test Method for Freezing Point of Aviation FuelsD2622 Test Method for Sulfur in Petroleum Products byWavelength Dispersive X-ray Fluorescence SpectrometryD2624 Test Methods for Electrical Conductivity of Aviationand Distillate FuelsD2700 Test Method for Motor Octane Number of Spark-Ignition Engine Fuel1This 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 July 1,2021.Published August 2021.Originallyapproved in 2011.Last previous edition approved in 2021 as D7719 21.DOI:10.1520/D7719-21A.2Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:D02-1721.ContactASTM CustomerService at serviceastm.org.3For 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 R
