Reference oil for testing dynamic viscosity

Use and characteristics of reference oil for testing dynamic viscosity

To meet the needs of manufacturers for the calibration and verification of rotary or vibration viscometers and consistometric cups, LNE offers reference oils in dynamic viscosity, the calibration of which can be carried out between 10°C and 70°C:

• Calibration at temperatures ranging from 20° to 70°C
• Calibration at temperatures of below 20°C and down to 10°C.

To calculate the dynamic viscosity of a fluid, a determination of the fluid mass density relies on the pycnometric method. 

Dynamic viscosity is the product of kinematic viscosity and the mass density of the oil.

*The relative uncertainty (k=2) depends on the actual dynamic viscosity range:

• 0.7 to 70 mPa.s: 0.6%
• 70 to 36,000 mPa.s: 1.2%
• 36,000 to 670,000 mPa.s: 2.0%

Packaging and storage

The oils are delivered in 500-ml, colored glass flasks with an indication of the kinematic viscosity value expressed in mPa.s for the requested calibration temperature(s). The oils must be conserved in their original flask, protected from both heat and light.

The oils are delivered with:

• Their safety data sheet
• A COFRAC calibration certificate calibration n°2-43

The oils must be stored in the original bottle, away from heat and light.
