标准摘要
[中文适用范围]： 本国际标准提供了一种测量材料、产品和组件在垂直方向暴露于受控点火源辐射加热水平的响应的方法。 该测试方法用于测定材料、产品和组件在通风良好的条件下的可燃性、热释放率、质量损失率和可见烟雾的产生。 热释放率通过测量氧气消耗量来确定，氧气消耗量是根据 5.5.8 中规定的排气产品流中的氧气浓度和流量确定的。 通过测量燃烧产物流对光的遮挡来量化烟雾的产生。 样本暴露于 0 kW/m2 至 50 kW/m2 的热通量下。 热丝用作点火源。 该测试方法是为材料、产品或装配评估、数学建模和设计目的而开发的。 样品的厚度和配置应代表实际的最终产品或系统用途。 本国际标准中的测试方法基于 ASTM E1623 中描述的设备。 [外文原描述]： ISO 14696:2009 provides a method for measuring the response of materials, products and assemblies exposed in vertical orientation to controlled levels of radiant heating with a piloted ignition source. The test method is used to determine the ignitability, heat release rates, mass loss rates and visible smoke development of materials, products and assemblies under well-ventilated conditions. The heat release rate is ascertained by measurement of the oxygen consumption as determined by the oxygen concentration and flow in the exhaust product stream. Smoke development is quantified by measuring the obscuration of light by the combustion product stream. Specimens are exposed to heating fluxes ranging from 0 kW/m 2 to 50 kW/m 2 . Hot wires are used as the ignition source.
