Codes & Standards
ACZA is listed in the American Wood Protection Association (AWPA) Book of Standards, section P5, for Waterborne Preservatives. Wood treated with this preservative is accepted in AWPA Standard U1 for applications in Use Categories 1 through 5, that is, from interior applications to salt water immersion. Within the requirements of the standards, ACZA can be used to treat numerous species of wood, however its ability to penetrate makes it particularly useful in the treatment of coastal Douglas fir, for which it is most commonly used.
AWPA standards are referenced in government specifications and model building codes for treated wood products. Chemonite® wood also qualifies under Canadian Federal (CSAK) Specifications.
Best Management Practices (BMPs)
The Western Wood Preservers Institute (WWPI), in conjunction with industry representatives, users, and scientists, developed BMPs to help ensure fixation of preservative chemical in treated wood prior to shipment. In the fixation process, preservative bonds to the wood, making it resistant to leaching. Specification of BMPs results in wood with a very high percentage of fixed preservative, and may also reduce shipping weight.
BMPs have been established for Chemonite® treated wood. Details are available on the WWPI web site (www.wwpinstitute.org) or by contacting a producer.

An editable model specification is provided here as a convenience to architects and design professionals to ensure that products purchased for a given project meet their intentions. Model specifications typically include criteria defined in building codes and industry standards, but may also include additional characteristics, such as warranties, third-party certification, and special properties, to provide desired features. As such, this model may be edited. We present it in electronic form as a service in order to save time and paperwork for specifiers.
