ICC-ES AC174
Full Name
ICC-ES AC174 – Acceptance Criteria for Deck Board Span Ratings and Guardrail Systems (Guards and Handrails)
Scope
ICC-ES AC174 is a set of acceptance criteria used to evaluate the performance of deck board span ratings and guardrail systems (guards and handrails). This evaluation is done in the context of building codes such as the International Building Code (IBC) and the International Residential Code (IRC).
Specifically, the scope of ICC-ES AC174 encompasses:
- Deck board span ratings: evaluating the structural capacity of deck boards to safely support loads. This evaluation considers factors like the wood species, grade, size, and spacing of the deck boards.
- Guardrail systems: assessing the strength and durability of guardrail systems, including both the railing itself and the connections to the deck or supporting structure. This evaluation involves testing for resistance to vertical and horizontal loads, as well as impact resistance.
The acceptance criteria cover various performance aspects, including structural integrity, durability, and safety. It provides a standardized framework for manufacturers and building officials to ensure that deck boards and guardrail systems meet minimum requirements for safety and performance.
