- Conclusions:
- Under the study conditions, the viscosity of the test substance ranged from 24.08 to 24.28 (average: 24.18) mm2/s at 20°C and was 10.93 mm2/s at 40°C.
- Executive summary:
A study was conducted to determine the viscosity of the test substance using a Cannon Fenske viscosimeter according to US EPA Guideline OPPTS 830.7300, in compliance with GLP. Under the study conditions, the viscosity of the test substance ranged from 24.08 to 24.28 (average: 24.18) mm2/s at 20°C and was 10.93 mm2/s at 40°C (Sloan, 1999).

- Value:
- 2.64
- Temp.:
- 40°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 6.45
- Conclusions:
- Under the study conditions the measured viscosity of the test substance was 2.64 mm²/s at 20°C and 6.45 mm²/s at 40°C (capillary viscometer).
- Executive summary:
A study was conducted to determine the viscosity of the test substance according to OECD Guideline 114. The determination was performed in duplicate at test temperatures of 20.0 ± 0.5°C and 40.0 ± 0.5°C by capillary viscometer. Under the study conditions the measured visosity was 2.64 mm²/s at 20°C and 6.45 mm²/s at 40°C (White, 2007).
