  • Description

    Accurately assess ignitability by testing exterior wall assemblies according to the methodology presented in the new NFPA 268.

    Revised to include updated references, the 2017 edition of NFPA 268: Standard Test Method for Determining Ignitability of Exterior Wall Assemblies Using a Radiant Heat Energy Source describes a method to determine the propensity of ignition of exterior wall assemblies from exposure to 12.5 kW /m2 radiant heat in the presence of a pilot ignition source.

    From instrumentation and documentation to safety precautions and calibration, NFPA 268 provides testing laboratories and manufacturers with the comprehensive testing guidance they need. (Print, 18 pp., 2017)
