Standard Test Method for Density and Relative Density (Specific Gravity) of Viscous Materials by Bingham Pycnometer. This method is commonly used for viscous liquids such as:
- Lubricating oils
- Bitumen and asphalt binders
- Resins
- Heavy petroleum fractions
- Some heat transfer fluids
The method determines:
- Density (mass per unit volume, e.g., kg/m³ or g/cm³)
- Relative density (specific gravity) at a specified temperature
It is particularly suitable for high-viscosity liquids that cannot be easily measured with hydrometers (like ASTM D1298) due to slow flow or air entrapment. The test uses a Bingham pycnometer, a specialized glass density bottle designed for viscous materials. Temperature control is critical because density changes significantly with temperature. The method requires a constant-temperature bath with tight stability.
The Tamson TV2000 is designed for ultra-precise temperature control. The TV2000 is able to achieve a temperature stability of 0.01°C. The TV2000 is maintenance free and designed to run with minimal operational costs. The TV2000 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. Optionally, the bath can be equipped with a Z41 backpanel illuminator to improve visibility.
The TV2000 is available in the following voltages/frequencies:
- TV2000 230V/50-60Hz (P/N: 00T0782)
- TV2000 115V/60Hz (P/N: 00T0784)
All accessories to be used in conjunction with ASTM D1480 are listed in the specification scheet

Common test temperatures are:
- 15 °C
- 20 °C
- 25 °C
- 40 °C
- 100 °C (for some heavy materials)
