ICC-ES AC77
Full Name
ICC-ES AC77 – Acceptance Criteria for Smoke-Containment Systems Used with Fire-resistance-rated Elevator Hoistway Doors and Frames and at the Intersection of Elevator Lobby and CorridorScope
ICC-ES AC77 outlines the requirements for smoke-containment systems specifically designed for use with fire-resistance-rated elevator hoistway doors and frames, as well as at the intersection of elevator lobbies and corridors. The scope of AC77 includes:- Smoke-containment systems: it focuses on systems intended to prevent or minimize the spread of smoke through elevator hoistway doors, frames, and the interface between elevator lobbies and corridors during a fire.
- Fire-resistance-rated components: it is specific to systems used in conjunction with fire-resistance-rated elevator components, ensuring that the overall fire safety of the elevator system is maintained.
- Performance requirements: it defines the criteria these systems must meet to be considered effective in containing smoke, including requirements for leakage rates, durability, and compatibility with fire-rated assemblies.
- Testing and evaluation: it outlines the testing procedures and evaluation methods to verify the performance and compliance of smoke-containment systems with the acceptance criteria.
