ASTM D7483-2021 Standard Test Method for Dynamic Viscosity and Derived Kinematic Viscosity of Liquids Using Vibrating Piston Viscosity Meters specifies a method for the measurement of dynamic and kinematic viscosity of liquids, such as lubricating oils, by means of an oscillating piston Viscosity meter. Measurement ranges from 0.2 mPa · s to 20,000 mPa · s and Temperature ranges from -40 ° C to 190 ° C. The principle is to use the electromagnetic drive piston to oscillate in the liquid. By measuring the average travel time and the ratio of up and down travel time of the piston, combined with the standard liquid calibrated Linear dispersion of known viscosity, the dynamic viscosity and kinematic viscosity of the liquid are calculated. The method is simple to operate and has high accuracy. It is suitable for transparent, translucent and opaque liquids, and is widely used in petroleum, chemical and mechanical lubrication fields.
