Designation:D480918Standard Test Method forHeat of Combustion of Liquid Hydrocarbon Fuels by BombCalorimeter(Precision Method)1This standard is issued under the fixed designation D4809;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 determination of the heat ofcombustion of hydrocarbon fuels.It is designed specifically foruse with aviation turbine fuels when the permissible differencebetween duplicate determinations is of the order of 0.2%.Itcan be used for a wide range of volatile and nonvolatilematerials where slightly greater differences in precision can betolerated.1.2 In order to attain this precision,strict adherence to alldetails of the procedure is essential since the error contributedby each individual measurement that affects the precision shallbe kept below 0.04%,insofar as possible.1.3 Under normal conditions,this test method is directlyapplicable to such fuels as gasolines,kerosines,Nos.1 and 2fuel oil,Nos.1-D and 2-D diesel fuel,and Nos.0-GT,1-GT,and 2-GT gas turbine fuels.1.4Through the improvement of the calorimeter controlsand temperature measurements,the precision is improved overthat of Test Method D240.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific warning statements,see Section 7,10.6,A1.7.1,and Annex A3.1.7 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: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 CalorimeterD1018 Test Method for Hydrogen In Petroleum FractionsD1193 Specification for Reagent WaterD1266 Test Method for Sulfur in Petroleum Products(LampMethod)D2622 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-lometryD3701 Test Method for Hydrogen Content of AviationTurbine Fuels by Low Resolution Nuclear MagneticResonance SpectrometryD4294 Test Method for Sulfur in Petroleum and PetroleumProducts by Energy Dispersive X-ray Fluorescence Spec-trometryD5453 Test Method for Determination of Total Sulfur inLight Hydrocarbons,Spark Ignition Engine Fuel,DieselEngine Fuel,and Engine Oil by Ultraviolet FluorescenceD7171 Test Method for Hydrogen Content of Middle Dis-tillate Petroleum Products by Low-Resolution PulsedNuclear Magnetic Resonance SpectroscopyE1 Specification for ASTM Liquid-in-Glass ThermometersE144 Practice for Safe Use of Oxygen Combustion VesselsE200 Practice for Preparation,Standardization,and Storageof Standard and Reagent Solutions for Chemical Analysis1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.05 on Properties of Fuels,Petroleum Coke and Carbon Material.Current edition approved July 1,2018.Published August 2018.Originallyapproved in 1988.Last previous edition approved in 2013 as D4809 13.DOI:10.1520/D4809-18.2For 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 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 Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.Terminology3.1 Definitions:3.1.1 gross heat of combustion,Qg(MJ/kg)3,nthe quan-tity of energy released when a unit mass of fuel is burned inoxygen in a constant volume enclosure,with the productsbeing ga
