ICC-ES AC294
Full Name
ICC-ES AC294 – Acceptance Criteria for Shutters for Protection Against Wind-borne Debris
Scope
ICC-ES AC294 outlines the acceptance criteria for evaluating permanently installed structural aluminum roll-up shutters designed to protect glazed openings from wind-borne debris.
The scope of AC294 includes:
- Materials: it specifies the acceptable materials for the shutters, including the aluminum slats, endlocks, guides, and fasteners.
- Design and construction: it details the design and construction requirements for the shutters, including the dimensions, thickness, and configuration of the components.
- Performance: it sets out the performance criteria that the shutters must meet, primarily focusing on their ability to withstand impact from wind-borne debris of specified sizes and velocities.
- Testing and evaluation: it describes the testing procedures to assess the performance of the shutters, including impact tests using standardized projectiles and wind pressure tests.
By establishing these acceptance criteria, ICC-ES AC294 ensures that shutters intended for protection against wind-borne debris meet the necessary safety and performance standards. It provides a standardized framework for manufacturers, designers, and building officials to evaluate the suitability of these shutters for various applications.
