This method specifies 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 range of kinematic viscosities covered in this test method is from 0,2 mm²/s to 300 000 mm²/s over the temperature range –20 °C to +150 °C. VTW Classic, NVB Classic, viscometer tubes (ubbelohde, CF opaque, CF routine…)
