Estimate the fire exposure behavior of floor covering systems with NFPA 253.

Knowing how different types of materials react to fire is critical to making informed selections. NFPA 253, Standard Method of Test for Critical Radiant Flux of Floor Covering Systems Using a Radiant Heat Energy Source, is referenced by NFPA 101®, Life Safety Code®, and building codes as the test procedure used to determine the critical radiant flux of floor covering materials.

Gain a critical basis for estimating one aspect of the fire exposure behavior of a floor covering system installed in a building corridor or exitway.

Innovative materials and new methods are continuously available to the construction industry. The 2019 edition of NFPA 253 has been updated and revised to address modern materials used for simulated concrete flooring. Annexes discuss how to calibrate an apparatus, mounting methods, sample data logs, proper application and interpretation of results, specific safety precautions, and more.
