Designation:D334322Standard Test Method forEstimation of Hydrogen Content of Aviation Fuels1This standard is issued under the fixed designation D3343;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This test method covers the estimation of the hydrogencontent(mass percent)of aviation gasolines and aircraftturbine and jet engine fuels.1.2 This test method is empirical and is applicable to liquidhydrocarbon fuels that conform to the requirements of speci-fications for aviation gasolines or aircraft turbine and jet enginefuels of types Jet A,Jet A-1,Jet B,JP-4,JP-5,JP-7,and JP-8.NOTE1The procedure for the experimental determination of hydro-gen in petroleum fractions is described in Test Methods D1018,D3701,D5291,and D7171.NOTE2The estimation of the hydrogen content of a hydrocarbon fuelis justifiable only when the fuel belongs to a well-defined class for whicha relationship among the hydrogen content and the distillation range,density,and aromatic content has been derived from accurate experimen-tal measurements on representative samples of that class.Even in thiscase,the possibility that the estimates may be in error by large amounts forindividual fuels should be recognized.The fuels used to establish thecorrelation presented in this test method are defined by the followingspecifications:FuelSpecificationAviation gasolinesD910Aircraft turbine and jet engine fuelsJP-4 and JP-5MIL-DTL-5624JP-7MIL-DTL-38219JP-8MIL-DTL-83133Jet A and Jet A-1D1655Miscellaneous hydrocarbonsNo.2 Diesel fuelKerosene distillates(similar to Jet A)Miscellaneous(includes thinners,gasoline fractions,and unidentified blends)Special production fuels(commercial products of nearly pure hydrocarbonsand special high-temperature fuels(HTF)produced for Air Force tests.Pure hydrocarbons1.3 The values stated in SI units are to be regarded as thestandard.1.3.1 ExceptionThe values given in parentheses are forinformation only.1.4 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.1.5 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 PressureD910 Specification for Leaded Aviation GasolinesD1018 Test Method for Hydrogen In Petroleum Fractions(Withdrawn 2021)3D1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD1319 Test Method for Hydrocarbon Types in Liquid Petro-leum Products by Fluorescent Indicator AdsorptionD1655 Specification for Aviation Turbine FuelsD2887 Test Method for Boiling Range Distribution of Pe-troleum Fractions by Gas ChromatographyD3701 Test Method for Hydrogen Content of AviationTurbine Fuels by Low Resolution Nuclear MagneticResonance SpectrometryD4175 Terminology Relating to Petroleum Products,LiquidFuels,and LubricantsD5291 Test Methods for Instrumental Determination ofCarbon,Hydrogen,and Nitrogen in Petroleum Productsand LubricantsD7171 Test Method for Hydrogen Content of Middle Dis-tillate Petroleum Products by Low-Resolution PulsedNuclear Magnetic Resonance Spectroscopy1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.04.0K on Correlative Methods.Current edition approved Nov.1,2022.Published November 2022.Originallyapproved in 1974.Last previous edition approved in 2016 as D3343 16.DOI:10.1520/D3343-22.2For 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.*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
