OECD 114: Viscosity of Liquids
The viscosity of fluids is environmentally relevant owing to the penetration of fluids into the soil and the harmful effect on the groundwater which may thus possibly be caused.
The purpose of the study is to evaluate the viscosity of using a rotary viscometer.
Course of the test
Apparatus - Haake Viscotester VT550 with application software
Test Conditions - 20 °C ± 0.2 °C and 40 °C ± 0.2 °C
9 mL test item will be filled into the cup and the sensor system will be fixed to the viscometer. The test item will be thermostated for at least 20 min at the specified test temperature. The viscosity at different shear rates will be determined. The software calculates the viscosity from the relevant measured values (speed, torque, and system geometry). If the viscosity will not vary at different shear rates the measurements will be performed at a constant shear rate.
At least two determinations will be made at each temperature.
The viscosity will be calculated from the relevant measured values (speed, torque, and system geometry) and the mean value [mPa s] at 20 °C and at 40 °C will be reported.
The conclusion whether the test item is one Newtonian or non-Newtonian fluid – will be reported.
(For Newtonian liquids, the viscosity is constant at all shear rates and depends only on the variables pressure and temperature. For non-Newtonian liquids, the viscosity will vary with shear rate.)
