Procedure for 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 dynamic viscosity can be obtained by multiplying the kinematic viscosity by the density of the liquid.

Procedure for the determination of kinematic viscosity of liquid asphalts (bitumens), road oils and distillation residues of liquid asphalts (bitumens) all at 60°C (140°F) and of asphalt cements at 135°C (275°F) in the range from 6 to 100.000 mm2/s (cSt).

For the determination of the kinematic viscosity of bituminous binders at 60°C and 135°C in the ranfge from 6 to 300.000 mm2/s (cSt). Bituminous Emulsions are not covered within the scope of this method..
