GB/T 6580-2021 Focused Glass performance testing, specifically for the erosion resistance of Glass to boiling mixed alkaline aqueous solution. It clearly stipulates the test method for this performance, including test equipment, solution preparation, operation process and other details. At the same time, based on the test results, a grading standard is formulated to clarify the degree of erosion resistance of Glass represented by each grade. The standard provides a unified specification for the Glass industry, helping enterprises to accurately evaluate the mass of Glass in a specific alkali environment, and provides strong support for the application and mass control of Glass products in related fields.
