标准摘要
[中文适用范围]： 1 适用范围 本文件描述了模拟由可燃气体释放、加压液化气体、闪燃液体燃料或粉尘可能引发火灾前的爆炸所产生的机械载荷作用于被动防火（PFP）材料及系统的方法。利用这些方法，可评估被动防火材料对此类事件的抵抗能力。本文件所涉PFP材料系应用于隔板、板材等可作为分区构件的载体。此类构件所承受的载荷主要源于爆炸超压作用，而阻力载荷通常可忽略不计。 [外文原描述]： This document describes methods for simulating the mechanical loads that can be imparted to passive fire protection (PFP) materials and systems by explosions resulting from releases of flammable gas, pressurized liquefied gas, flashing liquid fuels, or dust that can precede a fire. These methods can be used to determine the resistance of passive fire protection materials to such events. This document considers PFP materials applied to panels, plates, etc. that can be used as divisional elements. The loading on this type of element predominantly results from explosion overpressure applied and drag loadings are typically minimal.
