"JIS R1652-2003 Rotary Viscosity meter detection method for viscosity of ceramic slurry" is a Japanese industrial standard, which stipulates the method of using swirl/spin Viscosity meter to measure the viscosity of ceramic slurry. The standard is suitable for swirl/spin Viscosity meters of coaxial double cylinders, conical plates and parallel plates, etc., and is suitable for the viscosity determination of ceramic powder dispersion slurry at room temperature. Its main contents include Measurement principle, instrument requirements, operation steps and result calculation. This method can effectively evaluate the flowability and thixotropic of ceramic slurry, providing an important basis for slurry preparation, molding process optimization and product quality control in ceramic production.
