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.<\/p>\n
