Preface
This new edition of CSA Standard 080, Wood Preservation, supersedes the third edition published in 1962 and Supplement No. 1, published in 1965. Earlier editions were published in 1954 and 1959.
It differs mainly from the third edition in that two new CSA Standards have been added. The first, 080—C3, Marine Piles — Preservative Treatment by Pressure Processes, sets forth conditions and requirements for the treatment of Southern Pine, Pacific Coast Douglas Fir, Jack Pine and Red Pine. In addition retentions for both Atlantic and Pacific Coasts are specified. The second Standard 080—C28, covers preservative treatment of structural glued-laminated members — and — laminations before gluing — of coast region Doug}as Fir and Western Hemlock — by pressure processes.
A Foreword has also been added to this new edition covering recommendations for the use of AWPA and CSA Standards for wood preservation.
In essence, this Standard adopts by reference certain standards of the American Wood Preservers Association and, Where necessary, gives detailed supplementary requirements which are peculiar to Canadian wood species or conditions. The CSA Committee on Wood Preservation considered this form of standard to be the most practical and feasible to keep up-to-date. All annual technical changes to AWPA Standards are reviewed by the CSA Committee on Wood Preservation to ensure that these requirements are suitable for Canadian species and conditions. The need for Canadian requirements for established products and processes as well as new ones is kept under constant study. This Standard may be considered a minimum standard which may be modified, but which, if used without modification, will still protect the user.
This Standard was prepared by the Committee on Wood Preservation under the jurisdiction of the Sectional Committee on Timber, and was formally approved by these Committees and the CSA Technical Council.
Scope
