Abstract The issues of assessing the most important operational property of jet fuels, which is thermal oxidation stability, are reviewed in the article. It is under conditions of termination of foreign laboratory equipment supplies to Russia from the unfriendly countries. Following the statistical data about the application of GOST R 52954 (ASTM D3214) method, based on JFTOT American laboratory equipment unit, the inability of this method to perform the main task of its intended purpose is to rank domestic fuels for jet engines according to their thermal oxidation stability to determine their sort and area of application (subsonic or supersonic aviation). Differences in composition and properties of domestic and foreign jet fuels are considered as the reason for that. The termination of supplies of JFTOT laboratory equipment units and consumables to Russia dictates of import substitution when assessing the compliance of jet fuels in the Russian Federation. As an alternative to ASTM D method, a domestic method for determining thermal oxidation stability under dynamic conditions on DTS laboratory equipment unit is proposed, capable of reliably determining the brand and naming of Russian jet fuels. To implement this method, it is proposed to amend GOST 17751, GOST 10227, Appendix 5 to Technical Regulations TR CU 013/2011.
