GB/T 9989.5-2015 is the fifth part of a series of standards for the determination of chemical erosion resistance of enamels in closed systems. It specifies the relevant test equipment and sample preparation procedures, and specifies the operation steps for placing enamel samples in specific chemical reagents in a closed environment and performing tests according to set conditions. The corrosion resistance performance is assessed according to the standard by observing the chemical erosion of samples in closed systems. This standard provides a basis for evaluating the corrosion resistance of enamels in closed and complex chemical environments, and helps to ensure the mass and use effect of enamel products in corresponding special scenarios.
