ASTM D445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity)

Online Course • ASTM International

About the CPD course

This test method specifies a procedure for the determination of the kinematic viscosity; v; 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; n; can be obtained by multiplying the kinematic viscosity; v; by the density; p; of the liquid.
