This report compares the data on physical properties of synthesized hydrocarbon fuels and their blends with those of conventional Jet AJet A-1JP-8 fuels to look for opportunities to safely reduce the amount of fit-for purpose testing defined in ASTM D4054 in the approval process of synthesized kerosenes for use in jet fuel. The comparisons showed that for each property, the temperature dependencies and range of values are the same for all of the fuels, regardless of whether they were synthesized or natural. The evaluation concludes, based on fundamental physical chemistry, that all hydrocarbon kerosenes that meet the minimum density requirement will have bulk physical properties that are typical of conventional jet fuels regardless of resource or processing. These results lay the groundwork for combining all synthesized kerosenes into only a few Annexes in ASTM D7566 without regard to resource or processing.
