GB/T 3401-2007 stipulates the method for determining the viscosity of polyvinyl chloride (PVC) Resin dilute solution by capillary tubing Viscosity meter. The standard specifies the test principle, specifies the equipment, reagent materials, and sample preparation, and elaborates the solution preparation and viscosity measurement steps in detail, including thermostatic, solution flow time measurement, etc. At the same time, the result calculation and precision requirements are given, providing a unified technical standard for accurately obtaining the viscosity of polyvinyl chloride (PVC) Resin dilute solution, and assisting product mass evaluation and process control.
