ASTM D7541-11 (2022) Standard Practice for Estimating Critical Surface Tension provides a standardized practice for estimating material surface performance and aims to estimate critical surface tension (CST). Critical surface tension is an important parameter of material surface tension, which affects the wettability and adhesion of materials such as coatings and gluing agents. This standard provides methods for estimating material surface tension through laboratory testing and calculation formulas, and emphasizes the standardization of experimental conditions, reagent selection, and operating procedures. The method has important applications in areas such as surface preparation, coating technology, and product design, helping engineers predict how different materials will behave in real-world applications.
