GB/T 9269-2009 "Determination of Viscosity of Coatings - Stormer Viscometer Method" specifies the method for determining the viscosity of coatings using a Stormer viscometer, applicable to paints, varnishes, and related products. The principle involves measuring the mass of the weight required to rotate a specific rotor in the coating at a specified speed, which is then converted into the viscosity value of the coating. The test requires a Stormer viscometer, matching rotor, standard weights, and a constant-temperature water bath device. The operation is simple and fast, providing key data for production process control and performance evaluation of coatings during application.
