GB/T 23454-2025 "Stone Table Panels" is our country's national standard for Stone products for bathroom and home decoration. The standard was released by China Standard Publishing House and will be officially implemented on November 1, 2025, replacing the 2009 version of the standard. The standard specifies the technical requirements for hand sanitizers, window sills and other products made of natural Stone such as granite and marble, including Appearance mass, dimensional deviation, physical performance (such as water absorption, bending strength) and key indicators such as radioactive safety. The standard innovatively incorporates products such as washers and window sills into unified specifications, and refines the classification system of mirror/fine surface processing, general type/special type, etc., providing a unified mass evaluation basis for Stone processing enterprises.
