ASTM D2094-2000 (2006) specifies a standard operating procedure for the preparation of rod and rod specimens for adhesion testing. This standard provides detailed guidance for the manufacture and handling of adhesion specimens to ensure conformity and repeatability during adhesion testing. Test specimens are commonly used to evaluate the adhesion performance of Coatings, gluing agents, and Miscellaneous coating materials, which are suitable for different types of substrates. By following this standard, the accuracy and Reliability of adhesion tests can be effectively guaranteed, thus providing a scientific basis for material selection, product development, and quality control to ensure the durability and performance Stability of Coatings and Coatings in practical applications.
