ICC-ES AC151 – Acceptance Criteria for Fixed-height, Low-profile, Raised Floor Systems
Scope
ICC-ES AC151 outlines the acceptance criteria for fixed-height, low-profile, raised floor systems. These systems are commonly used in commercial and data center environments to provide space for underfloor services such as cabling, electrical wiring, and HVAC systems. The criteria cover various aspects of the raised floor systems, including materials, design, fabrication, and performance requirements.
Materials:
- Panels: types of panel materials (e.g., steel-clad, calcium sulfate, wood core), surface finishes, and edge treatments.
- Pedestals: types of pedestal materials (e.g., steel, aluminum), height adjustment mechanisms, and base designs.
- Stringers: types of stringer materials (e.g., steel, aluminum) and connection methods to panels and pedestals.
Design and fabrication:
- Panel dimensions and tolerances: maximum allowable deviations in panel size and flatness.
- Pedestal spacing and layout: requirements for pedestal spacing and layout to ensure adequate support for the panels.
- Electrical grounding and bonding: provisions for grounding and bonding the raised floor system to ensure electrical safety.
Performance requirements:
- Load capacity: minimum load-bearing capacity of the raised floor system for various load types (e.g., concentrated loads, uniformly distributed loads).
- Rolling load performance: resistance to rolling loads and impact loads.
- Fire resistance: minimum fire resistance rating for the raised floor system.
- Sound transmission: maximum allowable sound transmission through the raised floor system.
Testing procedures:
- Load testing: methods for testing the load-bearing capacity of the raised floor system.
- Rolling load testing: methods for testing the resistance of the raised floor system to rolling loads and impact loads.
- Fire testing: methods for testing the fire resistance of the raised floor system.
- Sound transmission testing: methods for testing the sound transmission through the raised floor system.
By adhering to ICC-ES AC151, manufacturers can ensure that their fixed-height, low-profile, raised floor systems meet the necessary safety and performance standards for use in construction projects. This helps to ensure the structural integrity, fire safety, and acoustic performance of buildings.
