ISO5660-1:2015材料热释放量测试/锥形量热法

BS ISO 5660-1:2015 Reaction to fire tests-Heat release, smoke production and mass loss rate-Part 1: Heat release rate(Cone calorinmeter method) and smoke production rate(dynamic measurement).
BS ISO 5660-1:2015 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(锥形量热仪法)

ISO5660-1:2015标准适用范围
This part of ISO 5660 specifies a method for assessing the heat release rate and dynamic smoke production rate of specimens exposed in the horizontal orientation to controlled levels of irradiance with an external igniter.The heat release rate is determined by measurement of the oxygen consumption derived from the oxygen concentration and the flow rate in the combustion product stream. The time to ignition (sustained flaming)is also measured in the test.

The dynamic smoke production rate is calculated from measurement of the attenuation of a laser light beam by the combustion product stream. Smoke obscuration is recorded for the entire test, regardless of whether the specimen is flaming or not.

ISO 5660-1标准概述
锥形量热试验是目前评估材料对火反应最先进的方法。ISO 5660-1测试按照物质燃烧的耗氧原理即被测物质与氧完全燃烧时消耗单位质量氧所产生的热量。另外，在测试过程中可以对产烟量和烟雾毒性进行测量。
该测试主要评估以下测试项目：
1 可燃性；
2 火焰传播；
3 产烟量；
4 烟雾毒性；

ISO 5660-1样品要求
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。
