Standard Test Method for Determining Ignitability of Exterior Wall Assemblies Using a Radiant Heat Energy Source
What is NFPA 268?
This standard offers a testing method to measure and describe the ignitability characteristics of exterior wall assemblies and their potential of contributing to fire growth under controlled laboratory conditions. It is intended to be used for code and other regulatory purposes, specification and design purposes, and research and development activities.
Official document scope
What does NFPA 268 address?
This test method evaluates flammability characteristics of interior textile wall coverings, measures certain fire performance characteristics, and determines the potential contribution to fire growth in a room and for fire spread beyond the room. Coverage includes test equipment. specimen mounting, instrumentation, calibration, test procedures, calculations, and documentation.
