At present, the low temperature test methods of hydraulic oil are characterized by low temperature kinematic viscosity, low temperature dynamic viscosity, low temperature pumping viscosity, low temperature brinell viscosity and pour point. In order to meet the different requirements of low temperature performance indexes of hydraulic oil products at home and abroad, the testing principles of various testing methods are introduced and analyzed, the flow performance of different testing methods under different working conditions is presented and the correlation between the methods is analyzed briefly.
