Quality Control of Plywood

Quality Control of Plywood
Each plywood plant has resident quality control personnel to help ensure that the finished panel will
meet the requirements sƟpulated in the manufacturing standards; CSA O121 and CSA O151 . Veneer
thickness, moisture control for veneer drying, panel grading, and glue bonding are examples of stages of
manufacture that are conƟnuously monitored in quality control.
In Canada, the vast majority of all construcƟon/industrial grade plywood is manufactured under a
quality system that includes audiƟng and control of in-plant procedures. These products are typically
idenƟfied by a cerƟficaƟon surface mark. This mark signifies that the plywood has been subject to an
accredited third party quality assurance program, which entails conƟnual monitoring of inner ply grade,
surface ply grade, panel thickness, panel dimensions, panel marking, workmanship, and glue bond
strength to ensure that the plywood will meet or exceed the requirements of the applicable
manufacturing standard
Other Canadian soŌwood/hardwood plywood plants may also employ voluntary quality audiƟng by
independent cerƟficaƟon agencies to ensure conformance to applicable requirements.
