ICC-ES AC301
Full Name
ICC-ES AC301 – Acceptance Criteria for Horizontally Sliding, Accordion-type, Fire-wall Assemblies
Scope
ICC-ES AC301 outlines the acceptance criteria for horizontally sliding, accordion-type, fire-wall assemblies used in building construction. These assemblies are designed to provide fire resistance and compartmentalization in large openings, such as those found in warehouses, factories, and commercial buildings.
The scope of AC301 includes:
- Materials: specifies the acceptable materials for the fire-wall assembly components, including the curtain material, guide tracks, operating mechanisms, and sealing systems. It also addresses the fire resistance ratings required for these materials.
- Design and construction: details the design and construction requirements for the fire-wall assembly, including the dimensions, configuration, and installation procedures. It also addresses the requirements for the structural stability of the assembly under fire conditions.
- Performance: sets out the performance criteria that the fire-wall assembly must meet, such as the fire resistance rating, smoke leakage rate, and operational reliability. It also addresses the durability and maintenance requirements of the assembly.
- Testing and evaluation: describes the testing procedures that must be conducted to verify that the fire-wall assembly complies with the acceptance criteria. This includes fire endurance testing, hose stream testing, and operational testing.
By establishing these acceptance criteria, ICC-ES AC301 ensures that horizontally sliding, accordion-type, fire-wall assemblies are safe, reliable, and meet the necessary building code requirements. It provides a standardized framework for manufacturers, designers, and building officials to assess the suitability of these assemblies for various applications.
