GB/T 9751.1-2008 "Paints and varnish - Determination of viscosity with swirl/spin Viscosity meter, Part 1: cone-plate viscometer operating at high shear rate" is a national standard for the determination of viscosity under high shear conditions in the coatings industry. The standard specifies the use of a specific cone-plate viscometer to determine the dynamic viscosity of Paints, varnish and related products within a high shear rate range of 9000s ¬ to 12000s, the results of which can reflect the flow resistance of the material during construction such as brushing and lame plating. The main test instrument explicitly used in the standard is the cone-plate viscometer, which has specific requirements for accuracy, reproducibility, and temperature control. In addition, this method is suitable for newtonian and non-newtonian fluids, but not for materials with large particle dispersion, so as not to damage the instrument or cause inaccurate results.
