ICC-ES AC326
Full Name
ICC-ES AC326 – Acceptance Criteria for Proprietary Wood Preservative Systems – Common Requirements For Treatment Process, Test Methods and Performance
Scope
ICC-ES AC326 establishes the common requirements for evaluating proprietary wood preservative systems. It outlines the criteria for the treatment process, test methods, and performance of wood preservatives used in various applications.
The scope of AC326 includes:
- Treatment process: it defines the requirements for the wood preservative treatment process, ensuring consistent and effective penetration of the preservative into the wood. This includes specifications for the types of preservatives, treatment methods, and quality control measures.
- Test methods: it outlines standardized test methods for evaluating the performance of wood preservatives, including their effectiveness against decay fungi, termites, and other wood-destroying organisms. These tests ensure the preservatives meet the required performance standards for different exposure conditions.
- Performance: it specifies the performance criteria that wood preservatives must meet to be considered acceptable for use in various applications, such as above ground, ground contact, and marine environments. The performance criteria are based on the intended use and expected service life of the treated wood.
- Documentation: it requires manufacturers to provide detailed documentation on the composition of their proprietary wood preservative systems, the treatment process, and the results of performance testing. This documentation is essential for evaluating the suitability of the preservative for specific applications.
The AC326 acceptance criteria are used by ICC Evaluation Service (ICC-ES) to evaluate proprietary wood preservative systems and issue evaluation reports. These reports provide evidence that the preservatives meet the requirements of the applicable building codes and standards, ensuring their safe and effective use in construction.
