Scope

This standard specifies the general principles for measuring the viscosity of liquids, emulsions, or suspensions of polymers and resins, including polymer dispersion systems, using a rotational viscometer with a standard geometric structure at a specified shear rate. The viscosity measurement conducted according to this standard involves determining the relationship between shear force and shear rate. The results obtained by different instruments in accordance with this standard are comparable, and both the test instruments and the shear force can be adjusted and controlled.
