Abstract: It is proposed to use the model hydraulic bench for assessing the stability of working fluids. The results of evaluation of changes in physical, chemical and operational properties of the working fluids during testing on the hydraulic bench are given. It is shown that the proposed work scheme for hydraulic bench allows assessing the stability of working fluids during test process. A fundamental technological scheme and description of work of the hydraulic bench that allows to model variable loads, pressure and temperature during work process of working fluids are presented. A program variant for testing of the working fluids is proposed for hydraulic fluid AMG-10 and possibilities for program estimation of the working fluids are described. Correlation of research results of the working fluids stability during testing on the model bench and in the hydraulic system of machinery during operation is determined
