GB/T 1723-1993 "Methods of Determination for Viscosity of Paints" specifies multiple methods for measuring the viscosity of paints, including the T-4 cup method, falling ball method, and rotational viscometer method, which are applicable to different types of paints. The T-4 cup method characterizes viscosity by measuring the time it takes for the paint to flow out of a standard viscosity cup, while the rotational viscometer method determines viscosity based on the resistance encountered by a rotating rotor. The testing requires instruments such as the T-4 viscosity cup, rotational viscometer, constant-temperature water bath, and stopwatch, providing standardized means for controlling the viscosity of paints during application.
