Conclusions:

The kinematic viscosity of the test item was determined to be 66.3 mm²/s at 25 °C.

Executive summary:

The kinematic viscosity of the test item was determined according to OECD Test Guideline 114, using a capillary viscosimeter (Ubbelohde viscosimeter). The liquid flowed under gravity through the capillary and the times when the liquid surface reached the start and stop marks were detected. Due to the fact that the test item has a melting point of 25 °C, the measurement was performed at 25 °C and 40 °C instead of 20 °C and 40 °C. The kinematic viscosity of the test item was determined to be 66.3 mm²/s and 28.6 mm²/s at temperatures of (25 ± 0.1) °C and (40 ± 0.1) °C, respectively.
