This method is for the determination of the kinematic velocity of both transparent and opaque liquid petroleum products using a calibrated glass capillary viscometer. A volume of liquid is allowed to flow under gravity through a calibrated glass capillary viscometer for a period of time.
They dynamic viscosity can also be obtained by multiplying the kinematic viscosity bby the density of the liquid.
The range of kinematic viscosities covered by this test method is from 0.2 to 300 000 mm2/s at all temperatures (refer to Table A1.1 of the method).
