GB/T 6753.4-1998 "Paints and varnishes - Determination of flow time by use of flow cups" specifies the method for determining the flow time of paints and varnishes using flow cups. It is applicable for assessing the fluidity of coatings. By measuring the time required for a specified volume of coating to flow out of a standard flow cup, the viscosity-related properties of the coating are characterized. The test requires instruments such as a standard flow cup, constant temperature water bath, stopwatch, and volumetric flask, providing data support for controlling the application viscosity of coatings.
