According to the surface quality of ceramic products, Chinese building materials standards can be divided into two grades: high-quality products and qualified products. Generally, high-quality products require bricks to be observed vertically at a distance of 0.8 meters without defects, and qualified products are observed at a distance of 1.5 M.
