ISO 14696:2009提供了一种用于测量垂直方向暴露的材料、产品和组件对受控水平辐射加热的响应的方法，该辐射加热具有导向点火源。 该试验方法用于测定材料、产品和组件在通风良好的条件下的可燃性、放热率、质量损失率和可见烟雾发展。 通过测量由排气产物流中的氧浓度和流量确定的氧消耗来确定热释放速率。通过测量燃烧产物流对光的遮蔽来量化烟雾发展。样品暴露于0 kW/m2至50 kW/m2的加热通量。热线被用作点火源。

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/m² to 50 kW/m². Hot wires are used as the ignition source.
