ICC-ES AC522 – Acceptance Criteria for Demountable (Relocatable) Partitions Used In Interior Applications
Scope
ICC-ES AC522 defines the acceptance criteria for evaluating demountable (relocatable) partitions used in interior applications within buildings. These partitions are designed to be easily installed, disassembled, and reconfigured, offering flexibility in space planning and adaptability to changing needs.
The scope of AC522 covers several key aspects, including:
- Structural performance: assessment of the partition’s structural integrity to withstand loads like wind pressure, impact, and racking forces.
- Fire resistance: evaluation of the partition’s fire-resistant properties, including materials and construction, to meet building code requirements.
- Sound transmission: measurement of the partition’s sound transmission class (STC) to determine its effectiveness in reducing noise transfer between spaces.
- Durability: assessment of the partition’s resistance to wear and tear, impact, and other factors that could affect its long-term performance.
- Installation: evaluation of the installation procedures and components to ensure proper assembly and functionality.
The evaluation process typically involves a comprehensive review of the engineering calculations, drawings, and supporting documentation submitted by the manufacturer. It may also include physical testing of prototypes to validate the design assumptions and verify performance under various conditions.
