ICC-ES AC307
Full Name
ICC-ES AC307 – Acceptance Criteria for Oriented Structural Straw Board (OSSB)
Scope
ICC-ES AC307 outlines the acceptance criteria for Oriented Structural Straw Board (OSSB), a type of engineered wood panel made from compressed agricultural straw.
The scope of AC307 includes:
- Materials: it specifies the requirements for the straw, adhesives, and other components used in the manufacture of OSSB, including allowable species, quality, and proportions.
- Manufacturing: it details the manufacturing processes for OSSB, including the formation, pressing, and finishing of the panels, to ensure consistency and quality.
- Physical and mechanical properties: it outlines the testing methods and acceptance criteria for evaluating the physical and mechanical properties of OSSB, such as density, thickness, bending strength, and stiffness.
- Bond performance: it specifies the requirements for the bond performance of OSSB, including the testing methods and acceptance criteria for evaluating its resistance to delamination and shear.
- Durability: it addresses the durability of OSSB, including its resistance to moisture, fungal decay, and insect attack, to ensure its long-term performance in construction applications.
- Quality control: it establishes a quality control program to ensure that OSSB products consistently meet the requirements of the acceptance criteria, including inspections and testing procedures.
The AC307 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their OSSB products comply with the applicable building codes and standards.
