ASTM D445
KINEMATIC VISCOSITY OF TRANSPARENT AND OPAQUE LIQUIDS (AND CALCULATION OF DYNAMIC VISCOSITY). This test method specifies a procedure for the determination of the kinematic viscosity, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, can be obtained by multiplying the kinematic viscosity, by the density, of the liquid.
