Applicant's summary and conclusion

Conclusions:
The mean dynamic viscosity of the test item was 66.0 mPa.s at 20.0 °C ± 0.2 °C and 31.5 mPa.s at 40.0 °C ± 0.2 °C.
Executive summary:

The objective of the test was to determine the dynamic viscosity (η) of the test item expressed in mPa.s. The method used is the viscometer with rotational spindles. The rotation of the spindle submerged in the test item allows to measure the torsion strength necessary to overcome the resistance due to the viscosity.

Taking into account the results obtained at 20.0 °C and 40.0 °C, the test item was considered to have newtonian properties in the experimental conditions used.

The mean dynamic viscosity of the test item was 66.0 mPa.s at 20.0 °C ± 0.2 °C and 31.5 mPa.s at 40.0 °C ± 0.2 °C.
