The GB/T 21059-2007 standard specifies a method for measuring the viscosity of polymers/Resins in liquid, emulsion or dispersion systems at specified shear rates using a swirl/spin Viscosity meter. The standard is suitable for viscosity measurement of various plastic materials. This method can effectively evaluate the rheological properties of materials and provide support for plastic processing and quality control.
