Conclusions:

The dynamic viscosity of the test substance at 20 °C was 24.83 mPas and the kinematic viscosity at 20 °C was 23.79 cSt. At 40 °C the dynamic viscosity was 10.45 mPas and the kinematic viscosity at 40 °C was 10.17 cSt.

Executive summary:

A study was conducted according to CIPC MT 192 and OECD TG 114 to determine the dynamic viscosity of the test item using the dynamic rotational viscometer method. The dynamic viscosity was determined to be 24.83 mPa*s at 20 °C and 10.45 mPa*s at 40 °C, respectively. The kinematic viscosity at both temperatures was calculated to be: 23.79 cSt at 20 °C and 10.17 cSt at 40 °C. No observations were made which cause doubt on the validity of the outcome of the study.
