Full Name
ICC-ES AC66 – Acceptance Criteria for Fire-retardant-treated WoodScope
ICC-ES AC66 establishes the guidelines for evaluating fire-retardant-treated (FRT) wood products. These products are designed to reduce the flammability and fire spread of wood used in construction. The scope of AC66 includes:- Material properties: it specifies the requirements for FRT wood products, including their fire-retardant properties, durability, and resistance to environmental factors.
- Testing procedures: it details the standardized testing methods for evaluating the fire performance of FRT wood products, including flame spread, smoke development, and structural integrity under fire conditions.
- Evaluation: it provides a framework for evaluating FRT wood products to ensure they comply with the acceptance criteria, including a review of their fire-retardant treatment, material properties, and test results.
