GB/T 21059-2007 specifies a method for determining the viscosity of liquid, emulsion, or dispersed polymer or resin systems using a rotational viscometer at specified shear rates. This method is applicable to systems exhibiting Newtonian or non-Newtonian flow behavior. By setting a constant shear rate, the apparent viscosity value is obtained, making it a fundamental method for evaluating the processing rheological properties of such materials.
