ISO 24679-1:2019

This document provides a methodology for assessing the performance of structures in the built environment when exposed to a real fire. This document, which follows the principles outlined in ISO 23932-1, provides a performance-based methodology for engineers to assess the level of fire safety of new or existing structures. NOTE The fire safety of structures is evaluated through an engineering approach based on the quantification of the behaviour of a structure for the purpose of meeting fire safety objectives and can cover the entire time history of a real fire (including the cooling phase), and its consequences related to fire safety objectives such as life safety, property protection and/or environmental protection.
