- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- May 27, 2003 - May 28, 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary viscometer (static)
- Key result
- Temp.:
- 20°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- ca. 24.5
- Conclusions:
- The kinematic viscosity of the test substance is 24.5 mm2/sec at 20°C.
- Executive summary:
The viscosity of the test substance was determined according to OECD guideline 114. The viscosity of the test substance was measured using the capillary viscosimeter at 20°C. The test substance was filled into the capillary viscosimeter and the efflux time was measured by the viscoboy equipment. This was repeated five times. For calculation of the kinematic viscosity, average value of the efflux time was taken. The kinematic viscosity of the test substance is 24.5 mm2/sec at 20°C.
- Endpoint:
- viscosity
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid
- Reason / purpose for cross-reference:
- data waiving: supporting information

Description of key information
Viscosity testing is not required for the powder form of the test substance. The viscosity of the liquid form of the test substance was determined according to OECD Guideline 114 using a capillary viscosimeter at 20°C (Keipert, 2003).
Key value for chemical safety assessment
- Viscosity:
- 24.5 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
The kinematic viscosity of the liquid form of the test substance was 24.5 mm2/sec at 20°C.
