ICC-ES AC504
Full Name
ICC-ES AC504 – Acceptance Criteria for Façade and Wall Cladding Systems with Porcelain, Ceramic or Terra Cotta Panels
Scope
ICC-ES AC504 outlines the acceptance criteria for evaluating façade and wall cladding systems that utilize porcelain, ceramic, or terra cotta panels. AC504 is intended for manufacturers seeking approval for their systems under the ICC-ES evaluation report program.
The scope of AC504 covers:
- Materials: defines the acceptable types of porcelain, ceramic, and terra cotta panels, as well as the supporting substructures, fasteners, and sealants that can be used in the cladding system.
- Performance requirements: specifies the structural, durability, fire resistance, and weather resistance properties that the cladding system 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 cladding system with the specified criteria. These tests may include wind load testing, impact testing, water penetration testing, and fire 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.
- Design considerations: provides guidance on design considerations for the cladding system, including attachment methods, joint design, and movement accommodation.
