标题:AS3837澳标防火测试_AS/NZS 3837热量与烟释放量的测试
正文:
许多国内建筑产品用于澳大利亚，新西兰等澳洲项目，需要证明其通过AS3837标准以证明其产品防火阻燃性能测试。咨询电话：025-8658 3475。AS/NZS 3837标准名称AS/NZS 3837:1998 Method of test for heat and smoke release rates for materials and products using an Oxygen Consumption CalorimeterAS/NZS 3837:1998 耗氧量法测定材料释热及烟雾释放速率方法AS/NZS 3837测试设备圆锥热量计量器火焰测试cone calorimeter fire testAS/NZS 3837测试指标(a) 热释放率，由氧气消耗量决定(Rate of heat release, by measurement of the oxygen consumption, as determined by the oxygen concentration and the flow rate in the exhaust product stream);(b) 有效热燃烧值和物质质量损失率(Effective heat of combustion from a concomitant measurement of specimen mass loss rate, in combination with the heat release rate);(c) 烟释放率(Smoke release, by obscuration of light by the combustion product stream);(d) 可燃性 ，产品加热后从不燃到可燃的时间(Ignitability, as a measurement of time from initial exposure to time of sustained flaming)。AS/NZS 3837测试方法及流程测试前，样品用锡箔纸(烤箱烧烤那种)包好4角和样品的底部形成一个托盘，用于存储可能的融化物。水平放置样品，火焰从一侧点燃，同时给样品以50kw/m2的热辐射加热。出现如下情况可以终止测试：1. 样品燃烧结束2分钟后;2. 平均物质质量损失率一分钟后降低到150gm2;3. 试验时
