ASTM D2170 is a Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens).

This test method covers procedures 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) (Note 1) in the range from 6 to 100 000 mm2/s (cSt).

Results of this test method can be used to calculate viscosity when the density of the test material at the test temperature is known or can be determined.

The Tamson TV4000 is designed for precise temperature control. The TV4000 is able to achieve a temperature stability of 0.01°C. All wetted parts are made of stainless steel and brass, providing resistance against all usual bath fluids. The bath is fitted with adjustable feet for leveling. The bath is equipped with two windows. The TV4000 is maintenance free and designed to run with minimal operational costs. The TV4000 can be operated from ambient +5 up to +230°C (..446°F). With the use of the built-in cooling coil, sub ambient temperatures down to +5°C can be achieved. The bath is equipped with both a drain and an overflow outlet. Also the viscosity bath is equipped with a float that will switch off the bath when the level of the bath fluid is too low. The bath conforms to CE-regulation. Further the bath is equipped with a mechanical over temperature protection. Optionally, the bath can be equipped with a Z41 backpanel illuminator to improve visibility.

The Tamson TV4000 can be used for viscosity determinations at these temperatures. The TV4000 offers seven positions for Cannon Fenske Opaque, Zeitfuchs Cross Arm or BS/IP/RF viscometers. The bath is completely conforms to ASTM D2170, D445 and ISO 3104.

The TV4000 is available in the following voltages/frequencies:

• TV4000 230V/50-60Hz (P/N: 00T0772)
• TV4000 115V/60Hz (P/N: 00T0774)
