- Guideline:
- OECD Test Guideline 114 (Viscosity of Liquids)
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7100 (Viscosity)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- rotational viscometer (dynamic)
- Key result
- Temp.:
- 40°C
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- 5 121
- Conclusions:
- The viscosity of the test material was determined to be 5121 mPa.s at 40.0 ± 0.5 °C and 1209 mPa.s at 60.0 ± 0.5 °C.
- Executive summary:
The viscosity was determined using a capillary viscometer method, designed to be compatible with Method 114 of the OECD Guidelines for Testing of Chemicals, 12 May 1981 and Method 830.7100 of the OCSPP Guidelines. The results are as followed:
Temperature (°C) Viscosity (mPa.s) 40.0 ± 0.5 5121 60.0 ± 0.5 1209
