GB/T 5547-2007 "Resin Finishing Agents—Determination of Viscosity" specifies the method for determining the absolute viscosity of resin finishing agents, applicable to the viscosity testing of various types of resin finishing agents. The rotating viscometer method is employed, where the sample is maintained at a constant temperature of 25°C ± 0.5°C. The appropriate rotor and rotational speed are selected, and the reading taken after the rotor rotates for 60s ± 2s is recorded, with the average value calculated. The test requires instruments such as a rotating viscometer and a constant-temperature water bath to ensure the rheological performance of the resin finishing agents meets standards during application.
