Standard test method for estimation of net and gross heat of combustion of burner and diesel Fuels

Scope

This test method covers the estimation of the gross and net heat of combustion in SI units, megajoules per kilogram, of petroleum fuels from the fuel density, sulfur, water, and ash content.
This test method is especially useful for estimating, using a minimum number of tests, the heat of combustion of burner and diesel fuels for which it is not usually critical to obtain very precise heat determinations.
This test method is purely empirical. It is applicable only to liquid hydrocarbon fuels derived by normal
refining processes from conventional crude oil that conform to the requirements of specifications for petroleum fuels. This test method is valid for those fuels in the density range from 750 kg/m3 to 1000 kg/m3 and those that do not contain an unusually high aromatic content. High aromatic content fuels will not normally meet fuel specification criteria.
This test method is not applicable to pure hydrocarbons. It is not intended as a substitute for experimental measurements of heat of combustion.
