ICC-ES AC518

Full Name

ICC-ES AC518 – Acceptance Criteria for Fiber-Reinforced Polymer (FRP) Composite Architectural Panel Systems Used as Exterior and Interior Wall Cladding

Scope

ICC-ES AC518 outlines the acceptance criteria for evaluating fiber-reinforced polymer (FRP) composite architectural panel systems used as exterior and interior wall cladding. AC518 is intended for manufacturers seeking approval for their systems under the ICC-ES evaluation report program.

The scope of AC518 covers:

  • Materials: defines the acceptable types of FRP composites, resins, and core materials that can be used in the panel systems, as well as the types of finishes and protective coatings.
  • Performance requirements: specifies the structural, durability, fire resistance (for exterior use), and weather resistance properties that the panel systems must meet. This includes requirements for wind load resistance, impact resistance, water penetration resistance, and fire performance.
  • Test methods: outlines the specific tests and procedures to be followed to evaluate the performance and compliance of the panel systems with the specified criteria. These tests may include structural testing, fire testing, weather resistance testing, and impact testing.
  • Quality control: details the quality control measures that manufacturers must have in place to ensure consistent product quality and compliance with the acceptance criteria. This may include requirements for material testing, production monitoring, and record-keeping.
  • Installation: provides guidance on proper installation methods and detailing for the panel systems to ensure optimal performance and longevity.
