木板ISO 5660-1 热量释放速率摸底测试
2022-06-11 08:34:00 【中科易朔】
ISO 5660-1 标准名称:
ISO5660-1对火反应试验—热释放、产烟量及质量损失率-第1部分:热释放速率
ISO5660-1 Reaction to fire tests-Heat release, smoke production and mass loss rate-Part 1: Heat release rate (cone calorimeter method)
样品规格:
样品规格:100 mm x 100 mm ,样品厚度小于50mm。对于试样实际厚度小于6mm的测试时应带上样品实际使用的基材使其整体厚度不小于6mm。
样本本面必须平整,而且样品必须能代表实际产品,最好是能跟最终产品类似,完整的测试需要12块样品,摸底测试2pcs样品。
测试过程:
将试样水平安装在设有特定辐射通量的辐射锥下,插入火花塞,点燃点火器。
下列情况,停止数据采集:
a)持续燃烧32min
b)试样在30min内未引燃
c)试样质量变为零
d)XO2回到测试前氧气浓度值0.01%范围内,持续10min
辐射通量为25kW/m2和50kW/m2,测试前需要确认辐射通量。
测试范围:
本标准规定了采用外部点火器,试样在水平定位受到可控制等级的热辐射时,测定热释放速率的方法。热释放速率的测量是通过燃烧产物气流中氧气浓度计算岀的氧消耗量和燃烧产物的流量来确定的,同时也对试样引燃(持续有焰燃烧)时间进行了测量。
建材其他防火测试标准:
EN 13501-1: 建筑制品和构件的火灾分级第一部分:用对火反应试验数据的分级
DIN 4102-1: 建筑材料和构件的防火性能第一部分:建筑材料要求和测试的分类等级
NF P 92-501: 法国材料阻燃防火测试M等级测定-刚性材料
NF P 92-503: 法国材料阻燃防火测试M等级测定-柔性材料
BS 476-6:建筑材料和构件的防火测试.第6部分:制品火势蔓延的测试方法
BS 476-7:建筑材料和构件的防火测试.第7部分:测定产品火焰表面蔓延分类的测试方法
