This Standard was prepared by the Subcommittee on Plywood, under the jurisdiction of the Technical Committee on Wood-Based Panels and the Strategic Steering Committee on Forest Products, and has been formally approved by the Technical Committee. It will be submitted to the Standards Council of Canada for approval as a National Standard of Canada.
