NFPA is considering the development of an ANSI Accredited Standard addressing the combustibility of exterior and interior wall panels. This test method would be based on the existing 16 ft. Parallel Panel Test from the FM Approvals Standard 4880, involving two facing vertical wall panels exposed to a 360 kW propane gas ignition source, representing a direct adjacent exposure. The parallel panel placement creates a re-radiation effect, representing severe exposures. The pass/fail criteria would be based on heat release rates measured under a calorimeter (1.5 MW minimum). This test would provide a cost effective solution to the other larger full-scale tests, such as the 25 to 50 ft high corner tests.
NFPA is seeking comments from all interested organizations and individuals to gauge whether support exists for standards development on a new wall panel fire test. Specifically, please submit your comments to the following:
1. Are you, or your organization, in favor of the development of an NFPA Standard pertaining to a fire test for wall panels?
2. Please state your reason(s) for supporting or opposing such standards development.
3. Are you, or your organization, in favor of the development of an NFPA Standard to establish a new fire test for wall panels?
Please submit all comments, in support or opposition, to the proposed standards development of fire test for wall panels by the deadline of September 12, 2017.
