4、ng 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 been derived fr
5、om 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 and Jet A fuels
