This document provides guidance for the specification of design fires for use in fire safety engineering analysis of building and structures in the built environment. The design fire is intended to be used in an engineering analysis to determine consequences in fire safety engineering (FSE) analyses.

Overview

ISO/TS 16733-2:2021 - "Fire safety engineering - Selection of design fire scenarios and design fires - Part 2: Design fires" provides guidance for specifying design fires used in fire safety engineering (FSE) analyses of buildings and structures. It defines how to represent a fire as an engineering load to assess consequences (life safety, property, environment, heritage) and to challenge fire safety systems. The document complements ISO 16733-1 (scenario selection) and aligns with the performance-based process in ISO 23932-1.

Key topics

Role of design fires in fire safety design and linkage to objectives such as occupant safety and property protection.

Elements of a design fire: incipient, growth, flashover, fully developed, decay/extinction stages; effects of suppression, ventilation and enclosure.

Constructing design fire curves: stepwise procedure covering input parameters, single/multiple fuels, power-law curves, flashover criteria, and maximum heat release rate for fuel-controlled and ventilation-controlled fires.

Modifying curves for suppression systems, fire service intervention, and enclosure effects.

Species production and yields (smoke and toxic products) relevant to life-safety and performance calculations.

Design fires for structural fire engineering: localized fires, ceiling/impinging flames, parametric fires, travelling fires and implications for thermal loading of structures.

External design fires, fire tests and probabilistic aspects (statistical representativeness, stochastic models, sampling).

Documentation requirements to record assumptions, input data and results.

Practical applications

Developing heat release rate (HRR) curves and time-temperature profiles for computational fire models (CFD, zone models) and engineering analysis.

Assessing smoke production and toxic species for egress and tenability studies.

Defining thermal loads for structural fire engineering and parametric fire design of elements.

Evaluating effects of active systems (sprinklers, suppression) and vent changes on fire growth and decay.

Supporting performance-based code compliance, risk assessments and peer-reviewed fire engineering reports.

Who should use this standard

Fire safety engineers, structural engineers, and modelling specialists.

Building designers, architects and consultants involved in performance-based design.

Code authorities, fire investigators and researchers who require standardized methods to define design fires.

Professionals conducting probabilistic fire risk assessments and documentation for regulatory review.
