NFPA 268 PDF

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.

It’s vital that manufacturers and testing laboratories have accurate procedures for testing the ignitability characteristics of building construction materials and components. NFPA 268 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
