This International Standard specifies a Procedure A using manual glass viscometers and a Procedure B using glass capillary viscometers in an automated assembly, 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, ?, is obtained by multiplying the measured kinematic viscosity by the density, ?, of the liquid. The range of kinematic viscosities covered in this test method is from (0,2 to 300000) mm2/s over the temperature range (- 40 to +150)°C.
