Administrative data
Link to relevant study record(s)
- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-10-20 to 2010-07-12
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC method MT 22 1994, reprinted 2007
- Deviations:
- no
- Principles of method if other than guideline:
- The viscometer is charged with sample to the upper charging mark with precaution, so that the walls above the mark are not made wet by sample. Sample is then allowed to flow in an unbroken column through the capillary to about 5 mm below the lower charging mark. The flow is stopped by closing the timing tube and more sample added to make up to the mark. The viscometer is then allowed to attain temperature equilibrium, and then the timing tube is opened to allow the sample to flow to the lower charging mark. The tube is closed again and the upper level of the sample is adjusted by adding or removing sample.
The timing tube is opened to allow the liquid to flow under its own head. The time, to within 0.2 seconds, is measured as the sample transverse the tube from the bottom of the lower timing mark to the upper timing mark. Liquid surface is taken as the uppermost portion of the advance liquid.
The viscometer is cleaned with a suitable solvent, dried, then refilled and flow time measurement is repeated. The difference between the repeated measurements must not be more than 0.2 seconds.
The kinetic viscosity for each run is obtained from the equation: Kinetic viscosity = C x T (cSt), where C = constant of the viscometer, T = Flow time in seconds - GLP compliance:
- yes
- Type of method:
- capillary viscometer (static)
- Specific details on test material used for the study:
- Component of a Polyurethane System
Polyoxypropylene triamine
(39423-51-3) 60-100% - Key result
- Temp.:
- 20°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 110
- Conclusions:
- The kinetic viscosity of the test substance was demonstrated as 110 cSt (mean of 2 results).
Reference
Kinetic Viscosity = 110 cSt (mean of 2 results)
Both the first and second run resulted in a kinetic viscosity of 110 cSt.
Description of key information
The kinetic viscosity was determined to be 110 cSt following a GLP study conducted according to CIPAC method MT 22 1994, using the capillary method (Baker, 2010).
Key value for chemical safety assessment
- Viscosity:
- 110 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
The outcome of the study is based upon two individual results for which the mean was taken to reflect the final value. Although no temperature was reported it was assumed that the study was conducted at ambient temperature.
