- Value:
- 5.365
- Conclusions:
- The determined average kinematic viscosity of the tested material at 20 °C was 11.1998 mm2/s and at 40 ºC was 5.3649 mm2/s.
- Executive summary:
The determination of kinematic viscosity of the test substance was performed according to the OECD 114 Guideline, with GLP. The Ubbelohde capillary viscometer was used and the measurements were performed at 20 and 40 ºC. The determined average kinematic viscosity of the tested material at 20 °C was 11.1998 mm2/s and at 40 ºC was 5.3649 mm2/s.
