Specifications include, but are not limited to: Fire-Test-Response Characteristics: 1. Perform penetration firestopping system tests by a qualified testing agency acceptable to authorities having jurisdiction. 2. Test per testing standards referenced in "Penetration Firestopping Systems" Article. Provide rated systems complying with the following requirements: a. Penetration firestopping systems shall bear classification marking of a qualified testing agency that inspects according to ASTM E 2174 1) UL in its "Fire Resistance Directory." 2) Intertek Group in its "Directory of Listed Building Products." INSTALLATION A. General: Install penetration firestopping systems to comply with manufacturer's written installation instructions and published drawings for products and applications. B. Install forming materials and other accessories of types required to support fill materials during their application and in the position needed to produce cross-sectional shapes and depths required to achieve fire ratings. 1. After installing fill materials and allowing them to fully cure, remove combustible forming materials and other accessories not forming permanent components of firestopping. C. Install fill materials by proven techniques to produce the following results: 1. Fill voids and cavities formed by openings, forming materials, accessories and penetrating items to achieve required fire-resistance ratings. 2. Apply materials so they contact and adhere to substrates formed by openings and penetrating items. 3. For fill materials that will remain exposed after completing the Work, finish to produce smooth, uniform surfaces that are flush with adjoining finishes. Finish surface similarly to adjacent surface (i.e. smooth and painted). D. See Life Safety and Code Analysis, sheet G1.2 for locations of rated wall or ceiling assemblies. E. Coordinate with mechanical and electrical documents for all locations where penetrations occur in rated assemblies and provide appropriate firestopping product.
