It supersedes the previous editions published in 2008, 1997, 1989, 1983, 1974, 1970, 1966, 1962, 1959, and 1954. This edition's technical requirements are organized in the Use Category System (UCS). The UCS is designed to facilitate selection of the appropriate wood species, preservative, penetration, and retention (loading) by the specifier and user of treated wood by more accurately matching the species, preservative, penetration, and retention for typical moisture conditions and wood biodeterioration agents to the intended end use. This Series of Standards consists of five Standards, as follows:
CSA O80.0, General requirements for wood preservation, specifies requirements and provides information applicable to the entire Series of Standards.
CSA O80.1, Specification of treated wood, is intended to help specifiers and users of treated wood products identify appropriate requirements for preservatives for various wood products and end use environments.
CSA O80.2, Processing and treatment, specifies minimum requirements and process limitations for treating wood products.
CSA O80.3, Preservative formulations, specifies requirements for preservatives not referenced elsewhere. The Technical Committee on Wood Preservation intends that CSA O80.3 will be used to accommodate additional preservative formulations (if any) in future editions of this Series of Standards.
CSA O80.4 has been withdrawn.
CSA O80.5, CCA Additives - Utility Poles, specifies requirements for preparation and use of CCA preservative/additiv
e combinations for utility poles permitted by CSA O80.1 and CSA O80.2.
Users of this Series of Standards should also note the following:
In 2012 PMRA registration requirements for Micronized Copper Azole (MCA) and Micronized Copper Quat (MCQ) were fulfilled and added to the CSA O80 Series of Standards
In 2013, requirements for alkaline copper quat, Type A (ACQ-A), were added to the CSA O80 Series of Standards.
The current edition of this Series of Standards also includes requirements for the treatment of hardwood and softwood crossties and switchties with ACZA.
Minimum requirements for fire retardant treatments are specified in Clause 8.9 of CSA O80.1 and Clause 9.8 of CSA O80.2. The Technical Committee intends that Clause 8.9 of CSA O80.1 and Clause 9.8 of CSA O80.2 will be used to accommodate standardized fire retardant treatments (if any) in future editions of this Series of Standards.
The process of including new preservatives to the CSA O80 Series of Standards have been included in CSA O80.0, Annex B.
The Technical Committee wishes to thank the American Wood Protection Association (AWPA) and its committee members for their assistance in developing CSA O80.1 and CSA O80.2 and adapting the UCS to Canadian needs.
