Qualifier:
according to
Guideline:
OECD Test Guideline 114 (Viscosity of Liquids)
Deviations:
no
GLP compliance:
no
Type of method:
rotational viscometer (dynamic)
Key result
Temp.:
20°C
Parameter:
dynamic viscosity (in mPa s)
Value:
16 400
Remarks on result:
other: an averaged viscosity value is indicated based on viscosity for two samples of the test substance: 16380 mPas (rotation speed 4 rpm) and 16360 mPas (rotation speed 2.5 rpm)

System check (20 °C):

Spindle no.:                      63

Rotation speed:               20 rpm

Reference oil certified:                      3301 [mPa x s]

Reference oil, measurement:              3270 [mPa x s]

Sample measurement (20 °C):

Spindle no.:                      63

Sample, meas. 1 (rotation speed, 4 rpm):        16380 [mPa x s]

Sample, meas. 2 (rotation speed, 2.5 rpm):       16360 [mPa x s]

Average dynamic viscosity (20 °C): 16400 [mPa x s]

Conclusions:
The viscosity of the test substance has been determined in accordance with OECD114 guideline. An averaged dynamic viscosity has been identified to be 16400 mPas, at 20 °C.

Description of key information

The dynamic viscosity of the substance has been determined to be 16400 mPa*s at 20 °C. Based on this, the substance does not need to be classified for aspiration hazard.
