ICC-ES AC167 – Acceptance Criteria for Fabric Air Dispersion Systems

Scope

ICC-ES AC167 outlines the acceptance criteria for fabric air dispersion systems used in HVAC applications. The criteria primarily focus on systems operating under positive pressure in exposed locations.

Key areas covered in the scope include:

  • Material properties: defining requirements for the fabric material, including tensile strength, tear resistance, puncture resistance, permeability, and fire resistance properties.
  • System design: evaluating the design of the air dispersion system, including ductwork, diffusers, suspension systems, and attachment methods, to ensure proper airflow distribution and structural integrity.
  • Performance testing: specifying testing procedures to assess the system’s air diffusion performance, pressure drop, and resistance to deflation under various operating conditions.
  • Installation requirements: outlining guidelines for proper installation of the fabric air dispersion system to ensure optimal performance and compliance with building codes and safety standards.
  • Maintenance and cleaning: addressing considerations for the maintenance and cleaning of the fabric material to maintain its functionality and hygiene over time.

By establishing these criteria, ICC-ES AC167 aims to provide a standardized framework for evaluating the safety, performance, and durability of fabric air dispersion systems, giving building officials, engineers, and contractors confidence in their use.
