On June 7, the NFPA Fire Test Committee is set to vote on a revision that would effectively change the NFPA Standard 285 (multi-story fire test for exterior walls).
A proposed ASTM standard will provide a needed set of guidelines for conducting and reporting on the on-site inspections of fire resistive materials. Anyone interested, particularly people with inspection experience, is invited to help create the standard.
Model code language addressing the intersection of a wall and a fire-rated floor-ceiling system continues to evolve in a manner that benefits a contractor who is willing to study and abide by the relevant code text.
The components or materials allowed in a tested fire resistive design are limited to those elements specifically identified in the description of the tested design.
