Designation:D452901(Reapproved 2011)Designation:381/97Standard Test Method forEstimation of Net Heat of Combustion of Aviation Fuels1This standard is issued under the fixed designation D4529;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 test method covers the estimation of the net heat ofcombustion at constant pressure in metric(SI)units,mega-joules per kilogram.1.2 This test method is purely empirical,and it is applicableonly to liquid hydrocarbon fuels derived by normal refiningprocesses from conventional crude oil which conform to therequirements of specifications for aviation gasolines or aircraftturbine and jet engine fuels of limited boiling ranges andcompositions as described in Note 1.NOTE1The estimation of the net heat of combustion of a hydrocarbonfuel from its aniline point temperature and density is justifiable only whenthe fuel belongs to a well-defined class for which a relationship betweenthese quantities has been derived from accurate experimental measure-ments on representative samples of that class.Even in this class,thepossibility that the estimates can be in error by large amounts forindividual fuels should be recognized.The JP-8 fuel,although notexperimentally tested,has properties similar to JP-5 and Jet A fuels andcan be considered in the same class.The classes of fuels used to establishthe correlation presented in this test method are represented by thefollowing applications:FuelSpecificationAviation gasoline fuels:Specification D910Grades 80,82,100/130,and 115/145Specification D6227DEF STAN 9190NATO Code F-18Aviation turbine fuels:MIL-DTL-5624JP-4,Avtag/FSIIDEF STAN 9188NATO Code F-40JP-5,Avcat/FSIIMIL-DTL-5624DEF STAN 9186NATO Code F-44JP-8,Avtur/FSIIMIL-DTL-83133DEF STAN 9187NATO Code F-34Jet A,Jet A-1,AvturSpecification D1655DEF STAN 9191NATO Code F-351.3 The net heat of combustion can also be estimated byTest Method D1405.Test Method D1405 requires calculationof one of four equations dependent on the fuel type with theprecision equivalent to that of this test method.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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:2D129 Test Method for Sulfur in Petroleum Products(Gen-eral High Pressure Decomposition Device Method)D240 Test Method for Heat of Combustion of Liquid Hy-drocarbon Fuels by Bomb CalorimeterD611 Test Methods for Aniline Point and Mixed AnilinePoint of Petroleum Products and Hydrocarbon SolventsD910 Specification for Aviation GasolinesD941 Test Method for Density and Relative Density(Spe-cific Gravity)of Liquids by Lipkin Bicapillary Pycnom-eter(Withdrawn 1993)3D1217 Test Method for Density and Relative Density(Spe-cific Gravity)of Liquids by Bingham PycnometerD1250 Guide for Use of the Petroleum Measurement TablesD1266 Test Method for Sulfur in Petroleum Products(LampMethod)D1298 Test Method for Density,Relative Density(SpecificGravity),or API Gravity of Crude Petroleum and Liquid1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products and Lubricants and is the direct responsibility of SubcommitteeD02.05 on Properties of Fuels,Petroleum Coke and Carbon Material.Current edition approved Dec.1,2011.Published April 2012.Originallyapproved in 1985.Last previous edition approved in 2006 as D452901(2006).DOI:10.1520/D4529-01R11.2For 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 States1 Petroleum Products by Hydrometer MethodD1405 Test Method for Estimation of Net Heat of Combus-tion of Aviation FuelsD1655 Specification for Aviation Turbine FuelsD2622 Test Method for Sulfur in Petroleum Products byWavelength Dispersive X-ray Fluorescence SpectrometryD3120 Test Method for Trace Quantities of Sulfur in LightLiquid Petroleum Hydrocarbons by Oxidative Microcou-lometryD4052 Test Method for Density,Relative Density,and APIGravity of Liquids by Digital Density MeterD4294 Test Method for Sulfur in Petroleum and PetroleumProducts by Energy Dispersive X-ray Fluorescence Spec-trometryD4809 Test Method for Heat of Combustion of LiquidHydrocarbon Fue
