ICC-ES AC09

Full Name

ICC-ES AC09 – Acceptance Criteria for Quality Control of Wood Shakes and Shingles

Scope

ICC-ES AC09 outlines the requirements and procedures for evaluating the quality control systems of manufacturers producing wood shakes and shingles. The scope of AC09 includes:
  • Quality management system (QMS): assessing the manufacturer’s QMS to ensure it has processes in place to control and monitor the quality of their products throughout production.
  • Material selection: evaluating the selection of raw materials, such as wood species and grades, to ensure they meet the required standards for strength, durability, and resistance to decay.
  • Manufacturing processes: examining the manufacturing processes, including cutting, drying, and finishing, to ensure consistent product quality and adherence to industry standards.
  • Testing and inspection: establishing requirements for testing and inspection procedures to verify that the finished products meet the specified performance criteria, such as dimensions, moisture content, and resistance to wind and fire.
  • Labeling and certification: requiring manufacturers to label their products with essential information, such as species, grade, and compliance with applicable standards, and to maintain records of quality control testing and inspection.
By defining the scope and criteria for quality control, ICC-ES AC09 helps ensure that wood shakes and shingles used in construction are of consistent quality and meet the minimum performance standards for safety and durability. This provides confidence to building owners, designers, and code officials that wood shake and shingle products are suitable for their intended use and will perform as expected.
