Conclusions:
The kinematic viscosity of the tested substance was determined to be 11.8 mm2/s at 20 ºC and was 5.93 mm2/s at 40 ºC.
Executive summary:

The kinematic viscosity was carried out in accordance with the OECD Guideline 114 with an Ubbelohde capillary viscometer (PN-EN ISO 3104). The determined average kinematic viscosity of the tested material at 20 °C temperature was 11.8 mm2/s and at 40 ºC was 5.93 mm2/s.
