ICC-ES AC331
Full Name
ICC-ES AC331 – Acceptance Criteria for Smoke and Heat Vents
Scope
ICC-ES AC331 establishes the requirements for smoke and heat vents to be recognized in an ICC-ES evaluation report under the International Building Code (IBC) and the International Fire Code (IFC).
The scope of AC331 includes:
- Materials: specifies acceptable materials for smoke and heat vents, including their fire resistance and durability properties.
- Design and construction: outlines design and construction requirements for the vents, ensuring proper operation and effectiveness in venting smoke and heat during a fire.
- Performance: defines the performance criteria that the vents must meet, such as the ability to open and close reliably under fire conditions, and to maintain their structural integrity.
- Testing: details the testing procedures used to evaluate the performance of smoke and heat vents, including fire exposure tests and operational tests.
By defining these criteria, AC331 ensures that smoke and heat vents meet the necessary safety standards and are compliant with building and fire codes. It provides confidence to building officials, designers, and fire safety professionals that these vents are suitable for their intended purpose of protecting lives and property.
