GB/T 9989.1-2015 is the first part of the standard for the determination of chemical erosion resistance of enamels, focusing on the determination of acid erosion resistance at room temperature. It details the required test equipment, standardizes the preparation process of enamel samples, and precisely describes the operation steps for placing the sample in a specific acid solution at room temperature. By observing the degree of acid erosion of the sample, acid resistance is assessed according to established standards. This part of the standard provides a key acid resistance detection method for enamel products in daily and industrial scenarios where they may come into contact with acid, helping to ensure product mass and service life.
