ISO International Standard

Describes a procedure for the estimation of the net specific energy of aviation fuels from their aniline point, density and sulfur content. Not applicable to pure hydrocarbons. The 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.
