ASTM 2196 – Standard Test Methods for Rheological Properties of Non-Newtonian Materials by Rotational Viscometer.
1.1 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 to 50 s−1 using a rotational viscometer operating in a fluid of “infinite” dimensions.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
