Full Name
ICC-ES AC428 – Acceptance Criteria for Modular Framing Systems Used to Support Photovoltaic (PV) Modules
Scope
ICC-ES AC428 sets the acceptance criteria for metal modular framing systems designed to support photovoltaic (PV) modules. This encompasses:
- Flush-mount systems: these are systems installed directly on roofs and walls of buildings.
- Freestanding systems: these are ground-mounted systems not attached to any building structure.
Key aspects covered by AC428:
- Structural design: outlines load requirements, connection capacities, and the overall structural integrity of the framing system under the International Building Code (IBC) and International Residential Code (IRC).
- Weather resistance: evaluates performance under wind, snow, and seismic loads.
- Durability: assesses material selection and corrosion resistance of the framing system components.
- Fire safety: addresses access for firefighters and other safety considerations in the system’s design.
In summary, ICC-ES AC428 focuses on the structural performance, safety, and durability of the modular framing systems used to support PV modules, ensuring they meet the necessary building code requirements.
