This standard provides information on specific nonpressure treated composite wood products, without the use of trade names or manufacturers names. Products listed in this standard are categorized using species or species mix, preservative type, adhesive type, manufacturing process and use class. All of these factors play an integral role in determining the performance of the finished product in specific applications. Users of this standard are urged to consult closely with the manufacturer of the treated composite to ensure it meets the criteria listed in section 5 of this Standard, Tables 5.1.1 to 5.1.6.

To be listed in this Standard, manufacturers of NPTC wood products must complete a data package and have it evaluated and offered for ballot to Nonpressure Subcommittee N-5, Composites. To prepare for this process, candidates are directed to the procedures found in the appendix of the AWPA Standards Book, titled ?Guidelines for the Evaluation of Non-Pressure Treated Composite Lumber Products, for consideration by the AWPA.? Successful completion of this process would result in a listing in the Standards.
