标准摘要
[中文适用范围]： ISO 5660 的本部分规定了一种评估试样热释放速率和动态产烟速率的方法，试样水平暴露于受控辐照度下，并使用外部点火器。热释放速率通过测量氧气消耗量来确定，该消耗量由燃烧产物流中的氧气浓度和流速计算得出。本测试还测量了点火时间（持续燃烧时间）。动态产烟速率通过测量燃烧产物流对激光束的衰减来计算。无论试样是否燃烧，都记录整个测试过程中的烟雾遮蔽度。 [外文原描述]： ISO 5660-1:2015 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 this 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.
