Abstract
These requirements detail a method of test intended to evaluate fire performance of metallic and nonmetallic roof deck constructions subjected to an internal (under deck) small scale fire exposure for the purpose of determining the contribution of the roof covering material, insulation, and other components of the roofing system to the spread of fire within a building. As the extend of flam propagation, thermal degradation, and combusitve damage are determined after roof deck constructions are exposed to controlled laboratory fire conditions as provided by a horizonal tunnel furnace, these requirements are not intended for use in describing or defining the fire hazard or risk of fire under actual fire conditions.
