A document outlining the precise requirements for doors designed to withstand fire for a specific duration. This file, often in a portable document format, details the materials, construction methods, hardware, and testing protocols necessary for a door assembly to achieve a specific fire-resistance rating. For instance, such a document might stipulate the type of core material, the intumescent seals required, and the approved listing agency (e.g., UL, Intertek) that has certified the assembly’s fire-resistance capability.
The availability of these structured outlines is crucial for ensuring life safety and property protection in buildings. They offer a standardized method for architects, contractors, and building officials to verify that a door meets the minimum fire-protection standards mandated by building codes. The existence of readily accessible requirements promotes consistent application of regulations and provides a clear benchmark for manufacturers. Historically, the development of standardized fire-resistance requirements has significantly reduced fire-related casualties and property damage.
