EN2825 Determination of smoke density
EN2825烟雾密度测定
EN2824-EN 2825-EN2826烟密度和烟气成分分析 - 标准简介
EN2824定义了测试设备，装置和介质，根据EN2825测定烟雾密度和根据EN 2826测定烟雾中气体成分浓度，由于在辐射热影响下或同时使用火焰时，厚度高达25 mm的固体材料和复合材料会发生热解分解。
Definesthe test equipment, apparatus and media required for determination of the smokedensity according to EN 2825 and the concentration of the gas components in thesmoke according to EN 2826 due to pyrolitic decomposition of solid materialsand composite materials of up to 25 mm in thickness under the influence ofradiant heat only or with simultaneous flame application.
