The DB44/T 999-2012 standard specifies the technical requirements for film ceramic bricks. The standard applies to ceramic bricks coated with a layer of film on the surface, which is widely used in the fields of architectural decoration, wall and ground laying. The standard describes in detail the material composition, coating performance, Appearance mass, dimensional tolerance, physical performance and durability requirements of film ceramic bricks, including scratch resistance, stain resistance, heat resistance and other technical indicators. Through the implementation of this standard, it is ensured that film ceramic bricks achieve the desired effect in terms of aesthetics and functionality, and at the same time improve the quality control level of products, and promote the development and application of architectural ceramic material technology.
