Standard Test Method for Shear Thinning Index of Non-Newtonian Liquids Using a Rotational Viscometer

Importancia y uso:

5.1 The flow behavior of many fluids of interest is non-Newtonian in nature. Non-Newtonian behavior is best studied using rheometry apparatus. Nonetheless, estimations on non-Newtonian behavior may be made by recording viscosity at differing rotational speeds (or shear rates) using rotational viscometers.

5.2 The shear thinning index provides a tool for the estimation of the amount of non-Newtonian behavior.

5.3 The shear thinning index may be used in quality assessment, trouble shooting, specification acceptance, and research.
