Designation:D771915aAn American National StandardStandard Specification forHigh Aromatic Content Unleaded Hydrocarbon AviationGasoline1This 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 under contract and is intended solely for useby purchasing agencies.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 fuel.It does not include all fuels satisfactory forreciprocating aviation engines.Certain equipment or condi-tions of use may permit a wider,or require a narrower,range ofcharacteristics 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 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 fuel at the time and place ofdelivery.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:3D86 Test Method for Distillation of Petroleum Products atAtmospheric 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 FuelD3237 Test Method for Lead in Gasoline byAtomicAbsorp-tion SpectroscopyD3606 Test Method for Determination of Benzene andToluene in Finished Motor and Aviation Gasoline by GasChromatography1This 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 Spark and Compression Ignition Aviation EngineFuels.Current edition approved Oct.1,2015.Published December 2015.Originallyapproved in 2011.Last previous edition approved in 2015 as D7719 15.DOI:10.1520/D7719-15A.2Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:D02-1721.3For 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 States1 D4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4171 Specification for Fuel System Icing InhibitorsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD4306 Practice for Aviation Fuel Sample Containers forTests Affected by Trace ContaminationD4809 Test Method for Heat of Combustion of LiquidHydrocarbon Fuels by Bomb Calori
