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 Corridor

Scope

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.
By providing a standardized framework for evaluating these specialized smoke-containment systems, ICC-ES AC77 contributes to the overall fire safety of buildings and helps protect occupants during fire emergencies.
