Conclusions:
The kinematic viscosity of the test substance was found to be 10580 mm^2 x s^-1 at 20°C and 1270 mm^2 x s^-1 at 40°C.

The dynamic viscosity of the test substance was found to be 11110 mPa x s at 20°C and 1340 mPa x s at 40°C.
Executive summary:

The viscosity of the test substance was determined at 20°C and 40°C using a pre-calibrated reverse flow capillary U-tube viscometer according to CIPAC MT 22 and OECD Method 414 guidelines under GLP. Under the conditions of the study, the kinematic viscosity of the test substance was found to be 10580 mm2.s-1 at 20°C and 1270 mm2.s-1 at 40°C and the dynamic viscosity was found to be 11110 mPa.s at 20°C and 1340 mPa.s at 40°C.
