The substance TFA is considered as a Newtonian liquid. Its viscosity is close to water.
The viscosity of the test substance TFA was measured according to
recognised methods, and under GLP, using a rotary viscometer. At a shear
rate varying from 20 to 100 s-1, the viscosity did not vary
significantly: 0.9 to 9.0 mPa s at 20°C. At a constant shear rate of
2000 s-1, the viscosity was measured to be 1.8 mPa s at 20°C,
and 1.6 mPa s at 40°C. Although these
results are below the
standard working range of the rotary viscometer (estimated
accuracy in this low viscosity range was checked to be ca 14%),
test item can be considered as a low viscous liquid.
