新国标发布 筑牢建筑防火“第一道闸门”

Core Viewpoint - The newly revised mandatory national standard "Classification of Combustion Performance of Building Materials and Products" (GB 8624-2025) will be implemented on January 1, 2027, marking a significant upgrade in China's building fire safety standards since its last comprehensive revision in 2012 [1][3]. Group 1: Key Changes in the New Standard - The new standard categorizes building materials and products into three main categories and nine subcategories, with building insulation materials further divided into five subcategories, enhancing precision in management [2]. - The scope of application has been significantly expanded to include new classifications, testing methods, and criteria for fire safety performance of building insulation materials and photovoltaic components [2]. - A multidimensional evaluation of combustion performance has been established, incorporating key additional grading information such as smoke production characteristics, burning droplets, and smoke toxicity into a four-dimensional evaluation system [2]. Group 2: Implications of the New Standard - The implementation of the new standard introduces a QR code and electronic labeling system for building insulation materials, creating a comprehensive fire safety supervision scheme from development to application [3]. - The standard provides a technical basis for the development of building-integrated photovoltaics, compelling manufacturers to enhance flame-retardant processes and purifying the market by eliminating substandard products [3]. - The new standard serves as a "safety red line" for building design, a "technical measurement" for material quality control, and a "legal basis" for fire safety acceptance, significantly contributing to the prevention of major fire safety risks in the construction sector [3].
