Standards Development
ISO 23693 part 1 aims to simulate the mechanical loads that could be imparted to passive fire protection (PFP) materials and systems by explosions resulting from the ignition of releases of flammable gas, pressurised liquefied gas, flashing liquid fuels or dust that may precede a fire. Explosions can give rise to pressure and drag forces. Damage to PFP materials and systems in an explosion can be caused by the direct effects of pressure and drag loadings and by the resulting distortion of the substrate supporting the PFP material. This part of the ISO 23693 series deals with tests to assess the performance of PFP materials applied to panels, plates etc that could be used as divisional elements. The loading on this type of element predominantly results from the explosion pressure applied and drag loadings are typically minimal.
ISO 23693-1 provides general requirements for calibration, undertaking, measuring and report blast tests intended to determine the response of passive fire protection (PFP) to gas explosions. The response of the PFP is partly dependent of the nature of the substrate, hence the requirement for additional parts of the series specifying the additional procedures relevant to a range of substrate types.
