2、ision,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)uni
3、ts,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
4、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
5、 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
6、 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 S
