This article presents the results of a study of the effect of temperature tests on indicators of thermal oxidative stability: optical density, evaporation, coefficient of thermal oxidative stability. A grapho-analytical model is proposed for determining these parameters for a wide range of temperatures without temperature control of oils using experimental results obtained at two temperatures. A comparative evaluation of the experimental data with the calculated ones obtained using the grapho-analytical model has been carried out.
