Full title and description

Life-threatening components of fire — Part 2: Methodology and examples of tenability assessment. This technical report provides practical guidance on applying ISO 13571 to evaluate the effects of fire effluents, heat and smoke on occupants and to estimate tenability and available safe egress times using both experimental and fire safety engineering examples.

Abstract

ISO/TR 13571-2:2016 explains methods of application, performance criteria and impact evaluation for assessing life‑threatening components of fire. It illustrates the procedure with two families of examples: application to real‑scale tests (Annex A and Annex B) and application within Fire Safety Engineering analyses (Annex C, D and E). The report is intended to support use of ISO 13571 in practical tenability assessments.

Scope

This Technical Report describes the practical application of ISO 13571 as a tool to evaluate the effects of fire effluents, heat and smoke on people and to estimate tenability and available safe escape time (ASET). It provides worked examples from full‑scale experiments and from fire safety engineering calculations to demonstrate methodology, assumptions and interpretation of results. The document is intended for practitioners performing tenability assessments and for those validating or interpreting experimental fire data.

Key topics and requirements

• Explanation of methods to assess individual life‑threatening components of fire: toxic combustion products, heat exposure and smoke obscuration.
• Performance criteria and end‑points for incapacitation and compromised tenability used to derive ASET.
• Worked examples applying the methodology to real‑scale test data (Annex A and B).
• Examples showing application within Fire Safety Engineering (Annex C, D and E), including calculation approaches and interpretation.
• Guidance on treating components independently and combining effects to determine the limiting tenability condition.

Typical use and users

Used by fire safety engineers, researchers, test laboratories, code authors and safety assessors who evaluate occupant tenability in building fire scenarios or interpret results from full‑scale fire tests. It is suited to professionals who need worked examples and applied guidance to implement ISO 13571 tenability methods in design, research and regulatory assessments.

Related standards

Related documents include ISO 13571 (guidance on estimating time to compromised tenability), ISO/TS and other TRs addressing fire effluent toxicity and model validation (examples: ISO 13571:2012 and other fire‑toxicity guidance such as ISO 29903 and IEC/EN documents on toxicity test interpretation). These provide complementary guidance on toxic potency values, model validation and fire hazard testing methods.
