This paper aims to characterise the rheological behaviour of hydraulic lubricants in relation to the testing temperature. The oil has been tested on a Brookfield rheometer with a cone plate geometry. In order to determine the rheological model, the variation between shear stress versus shear rate was measured. The thermal properties of the oil were measured by studying the dependence between viscosity and temperature. Finally, a few laws for the variation of the viscosity with temperature have been proposed.
