ASTM D445 method for kinematic viscosity of transparent and opaque liquids
4. Summary of Test Method4.1 The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature. The kinematic viscosity (determined value) is the product of the measured ...
