Structural and Non-Structural Wood Testing

Lumber and engineered wood products enjoy a long history of use in the building industry. As a result, many wood products already benefit from standard specifications and test methods created for and by their industry. That also leads to the expectation by building officials and professional designers that all wood products will comply with appropriate standards. With the pressure of developing new standards off their shoulders, forward-thinking manufacturers focus instead on working with the right third-party agencies to help them best comply with existing standards and meet their customers’ needs.

ICC NTA laboratories are accredited to the ISO 17025 standard, which ensures that you and your customers can rely on the validity of our results. Our team also understands how important test results are for your business goals and objectives — all our team members work together with you to efficiently conduct tests and prepare the test reports you need. We conduct code-compliance tests for various types of wood products, including but not limited to:

  • Formaldehyde emissions from wood-based panels
  • Laminated wood structural panel
  • Medium-density fiberboard (MDF)
  • Oriented strand board (OSB)
  • Oriented structural strawboard
  • Particleboard
  • Plywood
  • Proprietary sheathing
  • Proprietary wood structural panels
  • Structural wood-based and engineered wood products
  • Wood panel siding

As part of the International Code Council Family of Solutions, we work directly with ICC Evaluation Service, LLC (ICC-ES) to create tailored test plans that capture specialized requirements for innovative products, such as those found in the ICC-ES Acceptance Criteria. Test plans help ensure your innovative product has a clear path through the certification process with agreement from all participants. Below is a list of standards or criteria that may be included in test plans for wood products:

  • Airborne Toxic Control Measure (ATCM) as developed by the State of California’s Air Resources Board (CARB)
  • ANSI A208.1: Particleboard
  • ANSI A208.2: Medium Density Fiberboard (MDF) for Interior Applications
  • ANSI/APA PRP 210: Standard for Performance-Rated Engineered Wood Siding
  • ASTM D5456: Standard Specification for Evaluation of Structural Composite Lumber Products
  • ICC-ES AC14: Acceptance Criteria for Prefabricated Wood I-Joists
  • ICC-ES AC47: Acceptance Criteria for Structural Wood-based Products
  • ICC-ES AC182: Acceptance Criteria for Wood-based Structural Use Panels
  • ICC-ES AC266: Acceptance Criteria for Wood Structural Panel Roof Sheathing Factory-laminated with an Alternative Roof Underlayment
  • ICC-ES AC269: Acceptance Criteria for Racking Shear Evaluation of Proprietary Sheathing Materials Used as Bracing Wall Panels
  • ICC-ES AC307: Acceptance Criteria for Oriented Structural Straw Board (OSSB)
  • ICC-ES AC310: Acceptance Criteria for Water-resistive Membranes Factory-bonded to Wood-based Structural Sheathing, Used as Water-resistive barriers
  • PS 1: Structural Plywood
  • PS 2: Performance Standard for Wood-Based Structural-Use Panels
