sets requirements for producing, marketing and specifying softwood plywood used in a wide array of construction and industrial applications. It was last revised in2007. PS 2, last revised in 2004, is a performance-based standard resulting from efforts to harmonize U.S. and Canadian standards under the U.S.-Canada Free Trade Agreement. The standing committees of both standards are comprised of members representing panel manufacturers. suppliers. regulatory agencies. government, academia and inspection agencies. APA serves as a non-voting sponsor and technical advisor.
Thickness labeling changes, if adopted, would be designed to achieve consistency between provisions in PS / and PS 2 and those found in handbooks published by the National Institute of Standards & Technology.
