This document specifies a procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the 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 thermal oxidation 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.rd edition 2021-04 Petroleum products — Determination of thermal oxidation stability of gas turbine fuels Produits pétroliers — Détermination de la stabilité à l'oxydation thermique des carburéacteurs Reference number ISO 6249:2021(E) ？ ISO 2021 ISO 6249:2021(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2021 All rights reserved.
