JFTOT - A New Fuel Thermal Stability Test (A Summary of Coordinating Research Council Activity) 730385

This paper reports the results of an evaluation by the Coordinating Research Council (CRC) of a new test to measure the thermal stability of jet fuels. This new test, the jet fuel thermal oxidation test (JFTOT) by Alcor Inc., was designed to improve upon the ASTM-CRC Coker test.
The Alcor JFTOT is described as to fuel system, the heater test tube section, the thermocouple calibration tube rating methods-both visual rating and light reflectance methods, test program format, effect of test time on deposit formation, the heater tube temperature profile, and visual and tube deposit rater ratings. The relationship between the ASTM-CRC Coker and the JFTOT is evaluated, and the precision of the JFTOT and various measurements are discussed.
