Full Name
ICC-ES AC568 – Acceptance Criteria for Proprietary Designs and Alternate Configurations of Sheet Metal Ties for Anchored Masonry Veneer Construction
Scope
ICC-ES AC568 focuses on evaluating proprietary designs and alternate configurations of sheet metal ties for anchored masonry veneer construction. These ties are essential components that connect the veneer to the structural wall, ensuring stability and preventing detachment.
The scope of AC568 includes:
- Proprietary designs: assessment of sheet metal ties that deviate from the standard configurations prescribed in building codes, such as different shapes, materials, or connection methods.
- Alternate configurations: evaluation of ties that use standard materials and configurations but are used in non-prescriptive ways, such as with larger airspace between the veneer and the structural wall.
- Performance testing: conducting tests to verify the structural performance and durability of the ties under various loading conditions, including tension, compression, and shear.
- Corrosion resistance: assessing the corrosion resistance of the ties, especially in environments with high moisture or salt exposure.
The primary goal of AC568 is to ensure that proprietary and alternate tie designs meet or exceed the performance requirements of standard ties as outlined in building codes and standards. By meeting these criteria, manufacturers can obtain an evaluation report from ICC-ES, which can be used to demonstrate code compliance and gain approval for use in construction projects.
