This test method specifies a 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.
Bath can be operated from ambient +5°C up to +230°C. With the use of the built-in cooling coil and an external Tamson cooler, span lies 5K above the temperature of the cooling liquid. The TV2000, TV4000, and TV7000 have a bath volume of 20, 40, and 70 litres respectively. The TV2000 has a cover with three openings and lids. The TV4000 and TV7000 have a cover with seven openings and lids. These openings accommodate glass capillary viscometers in viscometer holders. The TV4000DC has the same specifications as the TV4000, but with a unique stability of 0,002°C at 40°C. The TV7000 is often used to calibrate long thermometers, to calibrate master viscometers or for oxidation stability tests. A bath overflow outlet protects from expanding bath oil when the bath filling is increasing at higher temperatures. A bath drain is standard included. The bath is fitted with a double window of which the front pane is detachable for cleaning purposes.
