ASTM D 445 - 06 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity)

American Society for Testing and Materials (ASTM). Current edition approved May 15, 2006. Published June 2006. 10p. This test method specifies a procedure for the determination of the kinematic viscosity, n, 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, h, can be obtained by multiplying the kinematic viscosity, n, by the density, r, of the liquid.
