- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study was carefully performed using capillary viscometers which in design and use are described in ISO3104 and ISO3105 (per OECD114). It is not known whether the viscometers used in this study are compliant with ISO standards nor whether the study was con
- Qualifier:

- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- GLP compliance:
- not specified
- Type of method:
- capillary viscometer (static)
- Temp.:
- other: 24.93°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- 0.392
- Remarks on result:
- other: Kinematic viscosities (Table 2) are reported in centistokes. This unit is equivalent to mm2/s.
- Conclusions:
- Kinematic viscosity of CAS# 756-13-8 at 24.93 °C is 0.3922 mm2/s.
- Executive summary:
The kinematic viscosity of CAS# 756-13-8 was measured at twelve temperatures by capillary viscometry using calibrated Schott-Ubbelohde glass capillary viscometers, along with a Schott AVS350 viscosity timing system and a Lawler temperature control bath. Factory-supplied calibrations were used, and Hagenbach corrections were applied (kinetic energy corrections) using interpolation of table values supplied with the viscometers. The kinematic viscosity of CAS# 756-13-8 at 24.93°C is 0.3922 mm2/s.
The study addresses kinematic viscosity directly, and is therefore relevant to the viscosity endpoint. The study was performed using capillary viscometers which in design and use are described in ISO3104 and ISO3105 (per OECD114). It is not known whether the viscometers used in this study are compliant with ISO standards nor whether the study was conducted in accord with GLP guidelines. Therefore the study is classified as acceptable with restrictions.
Reference
Experimental values of kinematic viscosity at several temperatures are reported in Table 2. Kinematic viscosity was correlated using the equation
KVisc (cS) = exp(660.0991/(T(°C) + 200) + 3.8731), R2= 0.99971

Derived values of kinematic viscosity from the above regression are reported in Table 3. The study report also contains derived values of density at the reported temperatures, and accordingly dynamic viscosities are calculated for this summary using tabulated values of water density.
