标准摘要
[中文适用范围]： 本文件旨在模拟可能在火灾发生前释放易燃气体、加压液化气体或闪蒸液体燃料而引起的爆炸，从而对被动防火 (PFP) 材料和系统施加的机械载荷。 本文件也适用于粉尘爆炸。 瓦斯爆炸会产生压力和阻力。 气体爆炸中 PFP 材料的损坏可能是由压力和阻力载荷的直接影响以及支撑 PFP 材料的基材的偏转造成的。 ISO 23693 系列的其他部分将处理一系列常见类型的样本，这些样本可以针对产生的机械载荷进行测试。 [外文原描述]： This document aims to simulate the mechanical loads that could be imparted to passive fire protection (PFP) materials and systems by explosions resulting from releases of flammable gas, pressurised liquefied gas or flashing liquid fuels that may precede a fire. This document can also be applicable to dust explosions. Gas explosions can give rise to pressure and drag forces. Damage to PFP materials in a gas explosion can be caused by the direct effects of pressure and drag loadings and by the deflection of the substrate supporting the PFP material. Other parts of the ISO 23693 series will deal with a range of common types of specimen that could be tested against the mechanical loads generated.
