This standard specifies a procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within a fuel system. It is applicable to middle distillate and wide-cut fuels, and is particularly specified for the performance of aviation gas turbine fuels.
The test results are indicative of fuel stability during gas turbine operation and can be used to assess the level of deposits that form when liquid fuel contacts a heated surface at a specified temperature.Falex
