The certified value of the viscosity standard was 4.92 mm2/s. The measured value was 4.86 mm2/s. The measured value is within ± 4 % which equates to an acceptable range of 4.92 ± 0.20 mm2/s, i.e. 4.72 to 5.12 mm2/s for the measured viscosity of the standard.

Conclusions:
The viscosity of the test item was assessed according to OECD guideline 114. The viscosity of the test item was determined to be 2.31 mm^2/s at 20.0 °C and 1.65 mm^2/s at 40.0 °C.
