Full Name

ICC-ES AC66 – Acceptance Criteria for Fire-retardant-treated Wood

Scope

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.
ICC-ES AC66 is crucial for manufacturers to demonstrate that their FRT wood products meet the necessary fire safety standards. It also assists building officials, designers, and contractors in selecting and using appropriate FRT wood for various applications where fire safety is a concern.
