This report compares test data on the compatibility of elastomeric materials with 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 results of two studies are presented 1 material properties of coatings, sealants, and O-rings at service temperatures, and 2 the effect of aromatics, natural and synthesized, on volume swell in these same materials. The results demonstrate that the responses of elastomers to kerosenes containing synthesized hydrocarbons are within the scope of responses to conventional jet fuels of similar aromatic content regardless of resource or processing. Also, the presence of cyclo-paraffins and tetralins plus indans do not affect the fundamental correlation with aromatic content at the concentrations used in the reported test programs.
