摘要
分析了用燃烧增长速率指数评价非铺地建筑材料及制品释热性存在的问题,提出了用最大平均热释放速率指数作为非铺地建筑材料及制品释热性评价参数的建议。聚氨酯硬泡沫保温板、阻燃细木工板、未阻燃细木工板、橡塑保温板、阻燃胶合板和未阻燃胶合板等6种材料的单体燃烧试验结果与数据分析表明,燃烧增长速率指数往往会过高估计测试样品的释热性,最大平均热释放速率指数较好地反映了测试样品在整个受火过程中的释热性。
The calculation method of fire growth rate index (FIGRA) is analyzed and maximum average rate of heat emission (mARHE) is suggested to describe the heat release behavior for building materials and products excluding floorings.The SBI tests are carried out for six typical materials including rigid polyurethane foam insulation,flame retardant wood planking,regular wood planking,rubber insulation,fire retardant plywood and regular plywood.The test results and data analysis show that FIGRA may overestimate the heat release hazard,and mARHE is reasonable to evaluate the heat release behavior.
