GB/T 23452-2009 is for natural sandstone building panels. It defines relevant terms and standardizes product classification and labeling. In terms of technical requirements, it stipulates the size deviation, Appearance mass and physical performance (such as bulk density, water absorption, bending strength, etc.) of the sheet. It also specifies the test methods of various performances, such as the accuracy of measuring tools for measurement size, the instruments and operating procedures for physical performance testing, and the inspection rules of products. The standard provides the basis for the production, mass inspection and engineering selection of natural sandstone building panels, and ensures their applicability and safety in architectural decoration and other projects.
