Saybolt universal second

The Saybolt universal second (SUS or SSU) is a measure of kinematic viscosity used in classical mechanics. It is the time that 60 cm of oil takes to flow through a calibrated tube at a controlled temperature, 38°C. The SUS is used for oils with flowing time up to 5600 seconds, in the range of low to medium viscosity such as machine oils.
