key study
Study period:
2012-04-03 till 2012-10-02
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
other: DIN 53019
Deviations:
no
Qualifier:
according to guideline
Guideline:
OECD Test Guideline 114 (Viscosity of Liquids)
Version / remarks:
(adopted, 12th May 1981)
Deviations:
no
Principles of method if other than guideline:
Viscosity at 20 °C:
For measurement of dynamic viscosity a commercially available rotational viscometer is used. The dynamic viscosity η is determined at 20 °C. The viscosity is determined applying shear rates within the range from 20 s-1 to 100 s-1 .
GLP compliance:
yes (incl. QA statement)
Type of method:
rotational viscometer (dynamic)
Temp.:
20°C
Parameter:
dynamic viscosity (in mPa s)
Value:
231

Result:

Dynamic viscosity at 20 °C: 231.6 mPa*s / 231.3 mPa*s

Mean value: 231 mPa*s

Conclusions:
The dynamic viscosity of the test item was measured at 231 mPa*s at 20 °C.
Executive summary:

The dynamic viscosity of the test item was determined according to DIN 53019 (OECD 114) by means of a rotational viscometer and showed a value of 231 mPa*s at 20 °C.

Description of key information

According to OECD Guideline 114, the dynamic viscosity of the test item was measured at 231 mPa*s at 20 °C.
