ASTM D2196
RHEOLOGICAL PROPERTIES OF NON-NEWTONIAN MATERIALS BY ROTATIONAL VISCOMETER.
These test methods cover the determination of the apparent viscosity and the shear thinning and thixotropic properties of non-Newtonian materials in the shear rate range from 0.1 s-1 to 50 s-1 using a rotational viscometer operating in a fluid contained in a 600 mL low form Griffin beaker.
