GB/T 5549-2010 "Surfactant, determination of surface tension by pull-up liquid membrane method", specifies the method of determining surface tension of surfactants by pull-up liquid membrane method. The standard specifies the test principle, standardizes the requirements of equipment and reagent materials, specifies the preparation of the sample, the determination steps and the calculation process of the results, and clarifies the key factors and operation details that affect the determination results. It provides a unified technical specification for the accurate determination of surfactant surface tension, and helps surfactant product performance evaluation and quality control.
