澳标AS/NZS 3837材料释热及烟雾释放速率方法
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 Calorimeter

AS/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150g/m2;
3. 试验时间超过60分钟;
4. 样品开始试验10分钟内不燃烧;
AS 5637.1及AS/NZS 3837等级划分
防火等级1级－不燃材料，material that does not reach flashover when exposed to 100KW for 600s followed by exposure to300KW for 600s.
防火等级2级－难燃材料，material that flashover flashover following exposure to 300KW within 600s after not reaching flashover when exposed to 100KW for 600s.
防火等级3级－可燃材料，material that reaches flashover in more than 120s but within 600s when exposed to 100KW.
防火等级4级－易燃材料，material that reaches flashover within 120s when exposed to 100KW.
