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.ISO5660-1:2015参考标准ISO 5
