Standard Test Method for Estimation of Net Heat of Combustion of Aviation Fuels (Withdrawn 2019)


1.1 This test method covers the estimation of the net heat of combustion at constant pressure in metric (SI) units, megajoules per kilogram or inch-pound units Btu per pound.

1.2 This test method is purely empirical and is applicable only to liquid hydrocarbon fuels derived by normal refining processes from conventional crude oil, which conform to the requirements of specifications for aviation gasolines, or aircraft turbine and jet engine fuels of limited boiling ranges and compositions as described in Note 1.

Note 1--The estimation of the net heat of combustion of a hydrocarbon fuel from aniline-gravity product is justifiable only when the fuel belongs to a well-defined class for which a relation between heat of combustion and aniline-gravity product has been derived from accurate experimental measurements on representative samples of that class. Even in this case, the possibility that the estimates may be in error by large amounts for individual fuels should be recognized. The classes of fuels used to establish the correlation presented in this test method are represented by the following specifications:

Fuel Specification
Aviation gasoline fuels:Specification D 910
Grades 80, 82, 100/130, and 115/145Specification D 6227
DEF STAN 91-90
NATO Code F-18
Aviation turbine fuels:MIL-DTL-5624
JP-4,Avtag/FSII DEF STAN 91-88
NATO Code F-40
DEF STAN 91-86
NATO Code F-44
Jet A, Jet A-1, AvturSpecification D 1655
DEF STAN 91-91
NATO Code F-35

1.3 This test method is not applicable to pure hydrocarbons. It is not intended as a substitute for experimental measurements of heat of combusiton.

1.4 The values stated in acceptable metric units are to be regarded as the standard.

1.5 The heat of combustion may also be determined in SI units by Test Method D4529. Test Method D4529 requires calculation of a single equation for all aviation fuels with a precision equivalent to that of this test method.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
