1、Designation:D1405/D1405M08(Reapproved 2013)Standard Test Method forEstimation of Net Heat of Combustion of Aviation Fuels1This standard is issued under the fixed designation D1405/D1405M;the number immediately following the designation indicates theyear of original adoption or,in the case of revisio
2、n,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This test method covers the
3、estimation of the net heat ofcombustion at constant pressure in SI units(megajoules perkilogram)or inch-pound units Btu per pound.1.2 This test method is purely empirical and is applicableonly to liquid hydrocarbon fuels derived by normal refiningprocesses from conventional crude oil,which conform t
4、o 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 aniline-gravity product is justifiable only when the fuel be
5、longsto a well-defined class for which a relation between heat of combustionand aniline-gravity product has been derived from accurate experimentalmeasurements on representative samples of that class.Even in this case,the possibility that the estimates may be in error by large amounts forindividual
6、fuels should be recognized.The classes of fuels used toestablish the correlation presented in this test method are represented bythe following specifications:FuelSpecificationAviation gasoline fuels:Specification D910Grades 80,82,100/130,and 115/145Specification D6227DEF STAN 9190NATO Code F-18Aviat

8、al measurementsof heat of combustion.1.4 The heat of combustion may also be determined in SIunits by Test Method D4529.Test Method D4529 requirescalculation of a single equation for all aviation fuels with aprecision equivalent to that of this test method.1.5 The values stated in either SI units or
9、inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.6 This standard does not purport
10、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 M
