GB/T 9751.1-2008 "Paints and varnishes — Determination of viscosity using rotary viscometers — Part 1: Cone-and-plate viscometer operated at a high rate of shear" specifies the method for determining the viscosity of paints and varnishes using a cone-and-plate rotary viscometer at high shear rates. By measuring the relationship between shear stress and shear rate through the relative rotation of the cone and plate with the sample, the viscosity is determined. The test requires the use of a qualified cone-and-plate rotary viscometer, a constant-temperature water bath device, and other equipment, providing accurate data for evaluating the rheological properties of coatings during application and controlling production processes.
