ASTM D4486 Test Method for Kinematic Viscosity of Volatile and Reactive Liquids
4. Summary of Test Method
4.1 The time is measured, in seconds, for a fixed volume of liquid to flow under gravity through the capillary of the viscometer under a reproducible driving head and at a closely controlled temperature. The kinematic viscosity is calculated from the measured flow time and the calibration constant of the viscometer.
5. Significance and Use
5.1 Kinematic viscosity is a physical property which is of importance in the design of systems in which flowing liquids are used or handled.
