GB/T 40280-2021 specifies the method for measuring the apparent viscosity of Resin in liquid, emulsion or dispersion plastics using a single-cylinder swirl/spin Viscosity meter. The standard specifies the scope of application and measurement principle, specifies the equipment, sample prepative, test steps, etc., and standardizes the calculation and precision requirements of the apparent viscosity. It provides a unified standard for scientific and accurate determination of the apparent viscosity of this type of Resin, which helps to control the mass of Resin products and optimize process parameters.
