ISO 16730-1:2015

Overview

ISO 16730-1:2015 - Fire safety engineering - Procedures and requirements for verification and validation of calculation methods - Part 1: General provides a structured framework for verification and validation (V&V) of calculation methods used in fire safety engineering. It applies to analytical models, algebraic correlations and complex numerical models (collectively called calculation methods), and defines requirements for demonstrating mathematical correctness (verification) and real‑world predictive accuracy (validation). The standard emphasizes documentation, quality assurance and appropriate reference data without prescribing specific fire models.

Key topics and requirements

• Verification processes
  • Code checking, temporal and spatial discretization checks, iterative convergence and consistency tests, and review of numerical treatments.
• Validation procedures
  • Open and blind validation approaches, comparison of model predictions with experimental/field data, and standardized reporting of validation results.
• Documentation requirements
  • Technical documentation (method descriptions, V&V evidence, worked examples) and user manuals (installation, input/output description, sample problems, error handling).
• Reference data quality
  • Requirements for selecting and documenting validation datasets and experimental data used to assess predictive capability.
• Sensitivity analysis and uncertainty
  • Guidance on sensitivity studies to identify influential parameters and informative annex material on uncertainty treatment.
• Quality assurance
  • Processes for software development, audits, and maintaining traceability of model development and testing.
• Special considerations
  • Guidance for probabilistic models and methods for assessment included in informative annexes.

Practical applications

• Verifying and validating CFD, zone and lumped-parameter fire models, empirical correlations and bespoke analytic solutions.
• Establishing credibility of calculation tools used for performance‑based fire safety design and risk assessments.
• Supporting regulatory acceptance and approval of modelling results submitted to authorities.
• Structuring model development and software quality assurance for vendors and research groups.
• Designing validation test plans and selecting appropriate experimental reference data for model benchmarking.

Who should use it

• Fire safety engineers and model developers
• Software vendors and QA teams for fire modelling tools
• Regulators, approving bodies and code developers reviewing model-based submissions
• Academics and educators teaching model validation and fire‑safety analysis methods

Related standards

ISO 16730-1 links to the broader fire safety engineering framework (e.g., ISO 23932) and complements standards on model-specific methods and data. Consult ISO 23932 and other parts of the ISO 16730 series for extended guidance on application within performance-based fire safety design.
