GB/T 23453 - 2009 is formulated around natural limestone building boards. It defines terms, classifies methods and marking rules. At the technical level, strict requirements are put forward on the specifications and size deviation of the board, Appearance defect standards, physical performance (including volume density, water absorption, bending strength, etc.). At the same time, the test methods of each performance index are given, covering the accuracy of measuring tools, the details of instrument operation, and the inspection and judgment criteria of products. The standard controls the production mass of natural limestone building boards, provides reference for engineering material selection, ensures its safe and effective application in architectural decoration and other projects, and improves architectural beauty and durability.
