Fire endurance tests were conducted on two floor/ceiling assemblies intended for use in modular housing. The floors were of plywood deck with vinyl or carpet overlay on light gage steel C joists. In the floor-ceiling assembly, the ceiling was separately supported on its own joists. During the tests the floors were loaded to represent the dead weight of structural parts bearing on them and a live load application of 40 psf. The test results are valid only for floors of similar construction loaded at or below the stress level developed by this loading. Failure of the floor with the protective ceiling assembly occurred by flame-through to the unexposed surface at 29 min., with extensive structural failure (collapse under load) following at 33 min. The unprotected floor over the crawl space had a flame through at 3 1/4 min., and structural failure following at 3 3/4 min. (Author Modified Abstract)
