THERMAL STABILITY OF AVIATION TURBINE FUELS BY JFTOT PROCEDURE: D3241
(Equivalent Test Methods: IP 323, ISO 6249, JIS K 2276B, and AFNOR M07-051)
EXPLANATION
This test method covers the procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. The test results can be used to assess the level of deposits that form when the liquid fuel contacts a heated surface at a specified temperature.
TEST SUMMARY
This test method uses the Jet Fuel Thermal Oxidation Tester (JFTOT) that subjects the fuel to conditions that can be related to those occurring in gas turbine engine fuel systems. The fuel is pumped at a fixed rate through a heater after which it enters a precision stainless steel filter where fuel degradation products may become trapped. The essential data derived are the amount of deposits on an aluminum heater tube, and the rate of plugging of a 17 μ nominal porosity precision filter.
TEST PRECISION
The precision of this test method is currently being determined.
This test method has no bias.
