- Temp.:
- 20°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 1.26
- Key result
- Temp.:
- 40°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 0.85
- Conclusions:
- The kinematic viscosity of the test item at 20°C and 40°C were 1.26 and 0.85 mm²/s respectively.
The determination of the kinematic viscosity were performed using calibrated glass capillary viscometer. - Executive summary:
The kinematic viscosity was determined by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer according to the OECD method (N°114) at 20°C and 40°C.
The kinematic viscosity of the test item at 20°C and 40°C were 1.26 and 0.85 mm²/s respectively.
Reference
Prior to the measurements of the kinematic viscosity of the mixture DS liquid, the equipment was controlled by measuring the kinematic of ultrapure water at 20 and 40°C. Difference between the Theoretical kinematic viscosity, mm²/s and the Measured kinematic viscosity, mm2 /s were -0.89% and -0.15% at 20°C and 40 °C respectively.

Description of key information
One reliable Key study is available. The kinematic viscosity was determined by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer according to the OECD method (N°114) at 20°C and 40°C.
Key value for chemical safety assessment
- Viscosity:
- 1.26 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
The kinematic viscosity was 0.85 mm²/s at 40°C.
