GB8624 Combustion Performance Classification of Building Materials and Products - Standard Name: 

• GB8624-2006: Combustion performance classification of building materials and products  

• GB 8624-2006: Classification for burning behavior of building materials and products

GB8624 Combustion Performance Classification of Building Materials and Products - Standard Overview:

• In the more than ten years since its implementation, GB8624 has served as a guideline for grading the combustion performance of China's building materials and some specific materials used inside buildings. It evaluates the fire performance of materials, guides fire safety design, implements fire safety supervision, and implements fire protection design specifications It has played an important role and produced significant social and economic benefits. 

GB8624 Combustion Performance Classification of Building Materials and Products - Standard Scope of Application: 

• GB8624 proposes a combustion performance classification procedure for all building materials and products. Architectural products are considered in their final form of application.

• GB8624 is applicable to two types of building products: floor coverings;
