Applicant's summary and conclusion

Executive summary:

The determination of the dynamic viscosity was performed according to DIN 53019 (German industry norm) and OECD 114 using a rotary viscosimeter at 20°C and 40°C. The kinematic viscosity was calculated with the dynamic viscosity and the density at test temperature. The following results were obtained:

Dynamic viscosity at 20 °C: 1.63 E-02 Pa · s

Dynamic viscosity at 40 °C: 8.6 E-03 Pa · s

Kinematic viscosity at 20 °C: 1.28 E-05 m2/s

Kinematic viscosity at 40 °C: 6.8 E-06 m2/s
