材料防火分级新体系和评估方法

THE NEW CLASSIFICATION AND EVALUATION SYSTEM FOR COMBUSTIBILITY OF INTERIOR SURFACE MATERIALS

新型复合材料的发展，对现行的材料防火分级体系提出了质疑．而如何科学地确定复合材料的燃烧等级，已越来越引起人们的关注．根据理论分析和试验结果，提出了以标型量热计试验为基础的材料防火分级新体系及评估方法。

Combustible classification is a very important problem for Building Materials, especial for complexmaterials .We have devoted to analysis their combustible classification by scientific method. This paper discussesthe testing results by cone calorimeter, and gives a new combustible classification system for interior surfacebuilding matenals.
