BS EN 1364-2:2018规定了一种测定天花板耐火性的方法，该方法包括: 其本身具有独立于其上方任何建筑构件的耐火性。这个欧洲人 本标准与EN 1363-1一起使用。该方法适用于通过吊架悬挂或直接固定在天花板上的天花板 支撑框架或结构，以及自支撑天花板。在本试验方法中，天花板暴露于火中，暴露方式为:a）从天花板下方，或b）从天花板上方，以模拟天花板上方空腔内的火。吊顶作为保护膜可能对耐火性的贡献 使用EN 13381-1中给出的程序确定承载元件的重量。耐火性 承重地板和吊顶也可以通过以下测试进行评估: 符合EN 1365-2。 交叉引用:EN ISO 13943EN 1363-2EN 1363-1:2012EN 13381-1购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 1364-2:2018 specifies a method for determining the fire resistance of ceilings, which in themselves possess fire resistance independent of any building element above them. This European Standard is used in conjunction with EN 1363-1.The method is applicable to ceilings, which are either suspended by hangers or fixed directly to a supporting frame or construction, and to self-supporting ceilings.Within this test method, the ceiling is exposed to fire, with the exposure being applied either:a) from below the ceiling, orb) from above the ceiling to simulate fire within the cavity above the ceiling.The contribution to fire resistance which a suspended ceiling might provide as a protective membrane to loadbearing elements is determined using the procedure given in EN 13381-1. The fire resistance of loadbearing floors in conjunction with a suspended ceiling can also be assessed by using tests according to EN 1365-2.Cross References:EN ISO 13943EN 1363-2EN 1363-1:2012EN 13381-1All current amendments available at time of purchase are included with the purchase of this document.
