ISO/TS 3814:2014

Overview

ISO/TS 3814:2014 - "Standard tests for measuring reaction-to-fire of products and materials - Their development and application" explains the purpose, development and appropriate use of the ISO reaction-to-fire test suite developed by ISO/TC 92/SC 1. The Technical Specification links individual laboratory-scale reaction-to-fire tests to the phases of a developing fire in buildings and transport, clarifying which tests produce meaningful data for fire safety engineering and which are of limited value. It explicitly notes that smouldering combustion is not addressed by existing SC 1 tests, and is intended to help reduce fire hazard through informed selection and interpretation of test results.

Key topics

• Relationship between reaction-to-fire tests and the stages of fire development (from ignition to fully developed fire).
• The intended scope and limits of laboratory-scale tests versus full-scale or enclosure tests.
• Common reaction-to-fire parameters: ignitability, surface spread of flame, smoke production and obscuration, rate of heat release, non‑combustibility, and corner/room fire behavior.
• Guidance on interpreting combined test results and indices, and cautions about correlating different national methods.
• Use of test data in fire hazard assessment and fire safety engineering for different fire scenarios.
• Identification of tests that yield relevant, reproducible data for risk reduction and regulatory use.

Applications

ISO/TS 3814:2014 is practical for:

• Selecting construction and interior materials based on reaction-to-fire performance to reduce ignition risk and fire growth.
• Interpreting laboratory test data in the context of real fire scenarios (pre-flashover vs fully developed fire).
• Integrating test results into fire safety engineering, design fire scenarios, and risk assessments.
• Informing regulatory decisions and harmonizing test methods across jurisdictions to reduce trade barriers.
• Guiding manufacturers and testing laboratories on which ISO tests provide useful parameters for product development and compliance.

Who should use it

• Fire safety engineers and consultants
• Regulators and code developers
• Material and product manufacturers
• Test laboratories performing ISO reaction-to-fire tests
• Project teams responsible for fire safety concepts in buildings and transport

Related standards

Key referenced ISO documents include:

• ISO 5660-1 (cone calorimeter - heat release & smoke), ISO 5657, ISO 11925-2/3 (ignitability), ISO 9239-1/2 (flooring behaviour), ISO 9705-1 (room corner test), ISO/TR 13387 series (fire safety engineering guidance), ISO 13785 (façade tests), and ISO 13943 (vocabulary).

ISO/TS 3814:2014 helps users choose and interpret the appropriate ISO reaction-to-fire tests so that laboratory results can be applied effectively in fire hazard reduction and safety design.
