Abstract : The tendency of liquid hydrocarbon-based fuels, such as kerosene, diesel fuel, and jet fuel toward the formation of fuel-insoluble solids during thermal stress in an aircraft fuel system is assessed by an accelerated test method comprising passing a predetermined quantity of a sample of fuel through a heated test section maintained at a predetermined temperature, at a predetermined fuel flow rate. A metal test strip, weighed before the test, is clamped in the heated test section during the test. It is weighed again after the test and the weight of solids buildup during the test is determined. It is related directly to the tendency of the fuel to form fuel-insoluble solids during thermal stress. A filter is weighed before the test. It is then connected to the outlet of the test section, and liquid fuel leaving the test section during the test is passed through it.
