The United States Pharmacopeia has stated that references to General Chapter <911> "Viscosity" will be changed to General Chapter <911> "Viscosity-Capillary Viscometer Methods," <912> "Rotational ...
Capillary viscometer and flow cups (orifice viscometers) The working principle of these instruments is based on the determination of the time needed for a standard volume of fluid to pass through a ...
Kinematic viscometers have historically been of the gravity-driven glass capillary type, as specified in ASTM D446, and directly measure kinematic viscosity following the ASTM D445 Test Method.
