Designation:D782615An American National StandardStandard Guide forEvaluation of New Aviation Gasolines and New AviationGasoline Additives1This standard is issued under the fixed designation D7826;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 guide provides procedures to develop data for usein research reports for new aviation gasolines or new aviationgasoline additives.1.2 These research reports are intended to support thedevelopment and issuance of new specifications or specifica-tion revisions for these products.Guidance to develop ASTMInternational standard specifications for aviation gasoline isprovided in Subcommittee J on Aviation Fuels OperatingProcedures,Annex A6,“Guidelines for the Development andAcceptance of a New Aviation Fuel Specification for Spark-Ignition Reciprocating Engines.”1.3 The procedures,tests,selection of materials,engines,and aircraft detailed in this guide are based on industryexpertise to give appropriate data for review.Because of thediversity of aviation hardware and potential variation infuel/additive formulations,not every aspect may be encom-passed and further work may be required.Therefore,additionaldata beyond that described in this guide may be requested bythe ASTM task force,Subcommittee J,or Committee D02upon review of the specific composition,performance,or othercharacteristics of the candidate fuel or additive.1.4 While it is beyond the scope of this guide,investigationof the future health and environmental impacts of the newaviation gasoline or new aviation gasoline additive and therequirements of environmental agencies is recommended.1.5 The values stated in SI units are to be regarded asstandard.1.5.1 Some industry standard methodologies utilize impe-rial units as their primary system.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D86 Test Method for Distillation of Petroleum Products andLiquid Fuels at Atmospheric PressureD97 Test Method for Pour Point of Petroleum ProductsD156 Test Method for Saybolt Color of Petroleum Products(Saybolt Chromometer Method)D323 Test Method for Vapor Pressure of Petroleum Products(Reid Method)D381 Test Method for Gum Content in Fuels by Jet Evapo-rationD395 Test Methods for Rubber PropertyCompression SetD412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD445 Test Method for Kinematic Viscosity of Transparentand Opaque Liquids(and Calculation of Dynamic Viscos-ity)D471 Test Method for Rubber PropertyEffect of LiquidsD664 Test Method for Acid Number of Petroleum Productsby Potentiometric TitrationD873 Test Method for Oxidation Stability of Aviation Fuels(Potential Residue Method)D892 Test Method for Foaming Characteristics of Lubricat-ing OilsD909 Test Method for Supercharge Rating of Spark-IgnitionAviation GasolineD910 Specification for Leaded Aviation GasolinesD924 Test Method for Dissipation Factor(or Power Factor)and Relative Permittivity(Dielectric Constant)of Electri-cal Insulating LiquidsD943 Test Method for Oxidation Characteristics of InhibitedMineral OilsD1002 Test Method for Apparent Shear Strength of Single-Lap-Joint Adhesively Bonded Metal Specimens by Ten-sion Loading(Metal-to-Metal)D1056 Specification for Flexible Cellular MaterialsSponge or Expanded Rubber1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.J0.02 on Spark and Compression Ignition Aviation Engine Fuels.Current edition approved Nov.1,2015.Published December 2015.Originallyapproved in 2013.Last previous edition approved in 2013 as D7823 13.DOI:10.1520/D7826-15.2For 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 States1 D1094 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 MethodD1621 Test Method for Compressive Properties of RigidCellular PlasticsD2240 Test Method for Rubber PropertyDurometer Hard-nessD2344/D2344M Test Method for Short-Beam Strength ofPolymer Matrix Composite Materials and Their LaminatesD2386 Test Method for
