NFPA 285 is defined as: the Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components. NFPA 285 assembly tests are required when exterior non-combustible walls contain combustible components per the International Building Code (IBC). The scope of materials classified by the IBC requiring NFPA 285 testing is increasing. Combined with more stringent energy code requirements, the use of combustible materials is also growing in exterior walls. The most common contributing factors to non-compliance of designs requiring NFPA 285 assembly testing include: −Lack of understanding of applicability of test on exterior wall assemblies. −Recent building and energy code changes causing new triggers for the test. −Lack of understanding of assembly vs. product results for NFPA 285 tests. This seminar will discuss the impact of the NFPA 285 Test on buildings using IBC-2018, the parameters and history of NFPA 285, which building envelope components are combustible and require NFPA 285 testing per IBC, and the paths to NFPA 285 code compliance that a designer can take. These elements all combine to integrate NFPA 285 compliant assemblies into building envelope systems.
