标准范围

ISO 834-9:2002规定了测定非承重天花板构件耐火性的试验程序，当暴露在天花板下方加热时，这些构件的耐火性独立于其上方的任何建筑构件。它适用于自支撑天花板和悬挂在支撑结构上或直接固定在支撑结构上的天花板。它不适用于用作水平防火屏障的天花板，用于保护上面的承重元件，在这种情况下，使用ISO 834-5将性能作为整个组件的一个组成部分进行评估。

ISO 834-9:2002 specifies test procedures for determining the fire resistance of non-loadbearing ceiling elements, which possess fire resistance independent of any building element above them, when exposed to heating from below the ceiling. It is applicable to self-supporting ceilings and to ceilings suspended from, or fixed directly to, a supporting construction. It is not applicable to ceilings used as a horizontal fire barrier for the protection of a loadbearing element above, in which case performance is assessed as an integral part of the complete assembly using ISO 834-5.
