Determination of the Hydroperoxide Potential of Jet Fuels

Abstract
In 1963 and in 1976, peroxide attack on certain engine rubber parts was found on some Far Eastern fuels. The problem was corrected by requiring oxidation inhibitor be added to fuels meeting Specifications DERD 2494 and MIL- T-5624. Because the majority of commercial aviation turbine fuel had not shown significant peroxide formation, CRC was requested to develop a technique which would identify the hydroperoxide-forming tendencies of jet fuels. Heating the fuel at 65 C for four weeks and measuring the peroxide number after four weeks is concluded to be an adequate Go/No Go test. Keywords: Gasturbines, Turbine components.
