GB/T 9988-2025 in English

This standard provides a method for evaluating the alkali resistance performance of enamel coatings. It outlines the procedures, equipment, and conditions necessary to conduct the test. The test involves exposing the coated material to an alkaline environment under controlled conditions to assess its durability and resistance to degradation. The standard specifies the preparation of test samples, the application of the alkaline solution, and the evaluation criteria for determining the extent of damage or change in the coating. It also includes guidelines for reporting the results and ensuring consistency in testing procedures. The standard is designed to ensure that the testing process is repeatable and reliable, facilitating the comparison of different materials and coatings.
