Besides a number of other parameters, brake fluid must fulfill viscosity specifications according to the respective standards. Kinematic viscosity is a very important, safety relevant parameter for automotive hydraulic fluids. Therefore, Anton Paar provides the SVM 3001 Stabinger Viscometer, an instrument measuring according to ASTM D7042 and ASTM D4052. It is an excellent solution for fast and economical measurement of low-shear kinematic viscosity in a wide temperature range between -60 °C and +135 °C.
Download this application report to see in detail how the SVM 3001 are used in the testing of automotive hydraulic fluids to get data comparable to ASTM D445.
