  • Description

    Help improve building fire safety by referencing NFPA 268, Standard Test Method for Determining Ignitability of Exterior Wall Assemblies Using a Radiant Heat Energy Source, 2022 edition.

    It's vital that manufacturers and testing laboratories have accurate procedures for testing the ignitability characteristics of building construction materials and components. NFPA 268, 2022 edition, outlines the methods for deciding the susceptibility of exterior wall assemblies to fire in the presence of a pilot ignition source.

    The document answers the need for standardized test procedures that complement fire test methods available within existing NFPA standards. Ignitability characteristics are tested when exposed to a radiant heat flux of 12.5 kW/m2 (1.10 Btu/ft2-sec) for 20 minutes.

    This resource can be used to measure and describe the properties of materials in controlled laboratory conditions and also as an element of a fire risk assessment.

    NFPA 268 is used in various processes, including:

    • Code and regulatory
    • Research and development
    • Specification and design

    The revised 2022 edition is the reliable source for the most up-to-date information and methods of testing the ignitability of exterior wall assemblies and their propensity for contributing to fire expansion.

    From procedures and specimens to calibration of equipment and safety precautions, NFPA 268 is your comprehensive resource to this method of product fire testing. The standard applies to exterior wall assemblies with flat, or almost flat, outward-facing surfaces. The 2022 edition is updated to address testing at different incident heat fluxes for larger fire separation distances.

    Help ensure you have access to the latest NFPA 268 knowledge and requirements.
