Conclusions:

The viscosity of 400112 was determined as 401.054 ± 1.579 mPa * s at 20.00 ± 0.04 °C.

Executive summary:

The viscosity of 400112 was determined according to OECD guideline 114 and EN ISO 12058-1 (2002) in a GLP certified testing facility.

The viscosity was determined as 401.054 ±1.579 mPa*s which is the mean of two determinations with three individual measurements each. Precision of the value is given as standard deviation of all six individual measurements. As the measured RSD was 0.39 %, the validity criterion for the used ball was met. Measurements were performed at 20.00±0.04 °C.

No observations arousing doubts concerning the accuracy of the results and the validity of the study were made.
