Abstract
Plywood panels that are being produced to meet the requirements of CSA O121M-1978 Douglas-fir Plywood, or of CSA O151M-1978 Canadian Softwood Plywood, may be repaired with synthetic patching materials within the limits set by the pertinent standard. The standards require that materials used for the purpose shall meet each of the tests described in this document.

Abstract
Face veneers for high-grade plywood have solid wood surfaces free from knots and defects. These plywood panels are used where a high quality finish is required or where the surface appearance is very important. For less strenuous requirements the use of a patching compound to cover and seal open defects has become accepted in the international market place. Certification agencies evaluate plywood panel quality and durability and offer consumer assurance that the panel will perform satisfactorily over an extended period. With evolution of the plywood industry and their suppliers, new patching materials and methods have come into use. The long-term performance of plywood patches made with these new materials and methods may affect the long-term durability of the plywood panel. Currently available literature was reviewed to determine if current plywood industry patch test methods are adequate to meet consumer needs.

Abstract
This energy use status report focuses on five commodity products produced within the broadly defined wood products sector: softwood lumber, softwood plywood, oriented strand board, particleboard and medium density fibreboard. The study examines gross facility manufacturing energy use and puts this energy use in context by relating it to upstream energy required to procure raw material and energy inputs. In addition, this work tracks both direct and indirect carbon emissions by fuel type and accounts for the carbon sequestered in wood products and thus, presents a carbon balance for each finished product at the plant gate. Using a life cycle analysis approach, this report documents the cradle-to-gate energy use in the production of the five commodities. Data reported here can assist each industry segment in better understanding material and energy use for the purpose of reducing energy consumption in the future.
