- Conclusions:
- The test item is non-Newtonian fluid with decreasing viscosity with increasing applied stresses. The viscosity at 20°C ranges from 270000 mPa.s at 2.5 rpm to 21.500 mPa.s at 100 rpm.
- Executive summary:
The viscosity is measured with the rotational viscometer at 20°C and 40 °C. No single value for dynamic viscosity is available. The test item is a non-Newtonian fluid with a decreasing viscosity for increasing stresses. The viscosity ranges from 270000 mPa.s at 2.5 rpm to 21.500 mPa.s at 100 rpm at 20°C and from 97000 mPa.s at 5.0 rpm to 11400 mPa.s at 100 rpm at 40°C.
