Abstract
A literature review was conducted to help develop a performance-based specifica- tion for materials intended to be used as the wearing course in forest roads built from unbound aggregate. A survey of eastern Canadian forestry companies revealed that few use appropriate specifications; instead, most use specifications that are designed for base-course layers and that typically lack sufficient plastic fines. Two aggregate wearing-course materials produced to meet different specifications were tested on a 10.2-km section of haul road with high traffic levels. A detailed performance evaluation and an analysis of the rate of road deterioration through the col- lection of surface roughness data revealed that both materials performed exceptionally well and significantly improved roads versus those without the specified wearing-course materials.

Abstract
A group of 2x4 SPF samples was tested for bending stiffness in the Western laboratory of Forintek and then re-tested in the Eastern laboratory . Another group of 2x4 SPF samples was tested for bending stiffness in the Eastern laboratory and then re-tested in the Western laboratory. The bending stiffness tests were conducted on test machines set up in accordance with ASTM Standard D198-02. Additional bending tests were done according to ASTM D4761-02A using the “portable bending” machine in the Western laboratory and a modified Metriguard 312 bending machine in the Eastern laboratory. Results from ASTM D198-02 bending stiffness tests showed a differences between the laboratories of 2.1% for the sample originating from the Western Laboratory and 1.5% for the sample originating from the Eastern Laboratory. The MOE bending test results were not adjusted to account for any increase or decrease in the moisture content of the specimens.

Abstract
This project evaluates the potential for non-structural panels in the furniture (including cabinetry) and interior finish industries in China. It entailed two stages: 1. Review of existing information on non-structural panel markets and industry in China; 2. Survey of wood-based panel manufacturers and non-structural panel specifiers in China. 137 furniture and 132 interior finish manufacturers in eastern and southern China were surveyed by phone, mail/fax, and in personal interviews. Personal interviews were carried out with 11 panel mills in the eastern region. The literature review is based on the Preliminary Competitor Analysis for Wood Products in China (Wahl and Gaston, 2003) that was carried out for Forestry Innovation Investment. Information specific to furniture, other non-structural panel markets and more recent publications have been added to this literature review.

Abstract
As this is a relatively new field much of the emphasis of this study was on a literature review to help develop a theoretical platform to work from. It was found that the colour of wood appears in the literature in two ways. It appears qualitatively in marketing and value-added research, and it appears quantitatively in colour matching and quality control research. The present research study is the first known occurrence of the quantitative comparison of measured colour with measured consumer preference. There has been considerable research into character marks in wood. This research has largely been based around traditional hardwoods as the result of increasing scarcity of high grades of lumber. However, more fundamental characteristics such a grain profile, rings per inch, and the presence of visual features such as rays and vessels have not been considered with respect to visual preferences. Consumer preference data used for this study originated from the study “Consumer visual evaluation of underutilized Canadian wood species” (Fell, 2002). This was chosen as it has a great variety of species to analyze. However, in the survey consumers evaluated the species for overall appearance and not for specific end-uses. Therefore results of the current study are general to wood used in the home and do not apply to specific end-uses.

Abstract
In this study builders and professional repair and remodellers were given a chance to evaluate 12 of the most common home siding products available in the market today. The products were evaluated on seven different attributes: price, maintenance, installation, attractiveness, status/image, fire resistance, and durability. Overall, fire resistance, attractiveness, and maintenance were selected as the most important product attributes by single-family homebuilders and repair & remodellers. The majority of respondents stated that their customers had a strong influence on their final choice of siding materials. In addition respondents were asked for their opinion regarding product popularity, rate of installation, substitution trends, and their choice of siding products for different categories of homes.

Abstract
This benchmarking study aims at providing the Canadian industry, agencies and governments with the necessary understanding of the knowledge and perception of wood roof trusses among specifiers in selected urban regions in China for ongoing and future promotions of wood roof trusses in China. The objectives of this project are the following: 1. Assess current awareness, knowledge and perception of wood roof trusses in multi-family housing among specifiers (architects, engineers and builders/developers); 2. Examine how decisions on roofing/building systems and materials are made; 3. Determine best ways to transfer knowledge about wood roof truss systems to specifiers. Two separate surveys were carried out for benchmarking wood use in roofs in China. The first survey was part of a survey of Chinese building specifiers (Benchmarking Chinese Building Specifiers (Cohen and Ding 2004)) carried out in October/November 2003. A second survey was administered during the Conference on Hybrid Building Construction in China and Wood Roof Truss Workshops in Shanghai and Beijing in December 2003.

Abstract
Pour fabriquer des produits à valeur ajoutée de qualité, il faut de bonnes techniques de collage. En effet, pour un fabricant, les problèmes de collage peuvent se traduire par une perte d’argent ou de clients, ou encore par une baisse de productivité ou des dommages à la réputation – des situations difficiles à corriger. Pour s’assurer que les produits en bois massif assemblés par collage sur chant, laminés ou aboutés, aient un rendement satisfaisant, les fabricants doivent accorder beaucoup d’attention à un certain nombre de variables qui ont une influence sur la qualité des joints collés. Il faut notamment tenir compte du produit et de son utilisation finale, du type d’adhésif, de la teneur en humidité et du mode d’entreposage du bois à coller, des propriétés du bois et d’un large éventail de variables allant de la préparation des surfaces jusqu’au mélange de l’adhésif, en passant par l’application de la colle et le contrôle de la qualité. Le présent document fournit un sommaire de ces principaux facteurs et de leur incidence sur la qualité des joints.

Abstract
This report provides the methods and summarizes the results of Forintek research to characterize the properties of British Columbia lumber containing beetle-transmitted bluestain. In 2003 Forintek Canada Corp. collected approximately 30 pieces of bluestained lodgepole pine lumber cut from beetle-attacked trees, and an equivalent amount of non-bluestained lumber from each of 14 different sawmills in the B.C. Interior. The geographic range of beetle attack was represented in the sampling plan. The wood was delivered to the Forintek Vancouver laboratory for conditioning and processing into test specimens. The specimens were allocated, in equal proportion from each mill, between tests of mechanical, dimensional stability/permeability, gluing, and finishing properties. This research represents the first comprehensive study and compilation of the properties of beetle-transmitted bluestained wood. Overall, the research indicates that this wood can be used, without compromising performance, for structural, furniture, and preservative-treated end uses. A factsheet summarizing the findings produced for customers of bluestained wood is included in the appendix to this report.

Abstract
Through the coordinated initiatives of industry and the Provincial and Federal governments, Canada has made significant progress in the acceptance of Canadian wood products and wood-frame construction in the codes and standards of China, Taiwan and South Korea. Technical input to support favourable revisions to the codes and standards in these countries has been spearheaded by Forintek staff, with support from representatives from various national organizations in Canada and the US. In this process, Forintek also has established a network of experts in these countries, which Canada can use in addressing potential future technical barriers. The effort has resulted in changes to the Chinese quality inspection code (GB 50206) and the timber design code (GB 50005). The GB 50206 was released in July 2002. The inclusion of North American wood frame construction and products has helped speed up inspection for wood frame construction in China. The GB 50005 was released in January 2004. The newly enacted code allows local engineers to design North American platform frame construction and specify North American species groups of structural lumber that are graded to rules that are compatible with those in Canada. Fire protection regulations have also been revised to position wood frame construction on the same playing field as buildings made of concrete and steel: for example, wood frame construction can now be built up to three storeys, and spatial separations can be as close as 4 m. Progress has also been made in Taiwan. The revised Taiwanese timber design code approved in 2003 contains engineering and pre-engineered designs adopted from North America standards. The submission of technical comparisons of the Canadian and Taiwanese standards to the Taiwanese government will help the Canadian forest industries to obtain Taiwanese regulatory recognition that Canadian wood products in compliance with Canadian standards will meet the pertinent Taiwanese standards. This recognition will give Canadian suppliers a head start in establishing a share of the Taiwanese market. The effort in 2003-04 builds on the successful working relationship established with the various codes and standards committees in China and Taiwan to assist them in introducing the North American wood frame construction system. Although it is understood that there are still a number of technical and market support items to address, this program ensures that a coherent infrastructure is developed to support the use of Canadian wood products in the Far East markets.

Abstract
Des essais en laboratoire et en usine ont été réalisés sur un humidimètre diélectrique commercial (Wagner, modèle L612) et la sonde accessoire pour utilisation dans les piles de bois (Wagner, modèle L712). Ces essais avaient pour but de caractériser et de quantifier les différents facteurs qui influencent la précision des mesures de teneur en humidité effectuées avec ce genre d’appareil. Les essais en laboratoire visaient à déterminer les propriétés du bois et les facteurs externes exerçant un effet sur les lectures. Les essais réalisés sur de l’épinette noire dont la teneur en humidité variait de 9 à 18% montrent la nécessité d’établir un nouveau facteur de correction pour cette essence. Les auteurs ont constaté que le gradient d’humidité, la température du bois, l’état de surface et la largeur des pièces affectent la lecture de l’humidimètre. Bien que non négligeable, l’effet de la température du bois ne représente qu’environ la moitié de ce qui a été observé dans le cas des appareils à résistance. La présence de nœuds ou de bois de compression dans la zone d’essai influence aussi les lectures. La température de séchage n’a par contre aucun effet détectable. Des essais industriels réels et simulés ont permis de valider les différentes corrections établies lors des essais en laboratoire. Dans le cas de l’épinette noire, il s’est avéré possible d’améliorer la mesure de la teneur en humidité par l’emploi d’un nouveau facteur de correction pour l’essence et, selon l’application considérée, par l’emploi de facteurs de correction pour la température du bois, l’état de surface, etc. Certains essais ont également porté sur la sonde d’échantillonnage. Même dans les conditions bien contrôlées du laboratoire, il a été difficile d’obtenir une bonne corrélation entre les lectures prises à l’aide de la sonde et celles obtenues directement avec l’humidimètre portable ou par dessiccation au four. La sonde a généralement pour effet de sous-estimer la teneur en humidité du bois. Les lectures se sont avérées plus précises et plus uniformes lorsqu’elles ont lieu dans les piles de bois de température uniforme. Des comparaisons ont été effectuées entre les lectures des deux types d’humidimètre portable (diélectrique et résistance) en rapport avec la teneur en humidité mesurée au four de pièces de bois séchées en laboratoire et en usine. La proportion de lectures comprise dans une plage d’erreur donnée s’avère légèrement supérieure dans le cas de l’appareil à résistance. Il est possible d’établir une corrélation entre les lectures de l’humidimètre diélectrique et celles de l’appareil à résistance indépendamment des facteurs de correction utilisés.

Abstract
This second report for project entitled “Reduction in Folded strands to Improve OSB Properties” contains studies of flaking yellow birch to reduce strand folding plus additional studies carried out on aspen to further understand the basic mechanisms of strand folding. In this report, the impacts of wood temperature and counter knife angle were investigated. The effect of flaking parameters on strand tensile strength, flaking energy and strand size distribution was also investigated. Different ways to reduce strand folding were tested, including: flaking birch wood with different knife projections and with different knife clearance angles, drying strands at different temperatures; longitudinal flaking at different rake angles, microbevel angles and different strand lengths. In addition basic flaking studies were carried out to evaluate tangential flaking of aspen wood from different locations with different moisture contents, different counter knife thicknesses and different tilt angles. Strands with different curl indexes were correlated with panel performance in order to study the impact of strand folding on panel properties. A key finding was that birch strands were more liable to yield folded strands compared to aspen strands. Counter knife angles of 78° and wood temperature of 21°C tended to yield the lowest birch strand folding. Increasing strand thickness and decreasing knife clearance angle decreased the folding of both birch and aspen. Flaking birch strands with a large rake angle and microbevel reduced strand folding. Strand folding was also dependent on strand drying temperature and strander knife clearance angle. Drying wood at different temperatures resulted in different levels of strand folding. The impact varied among wood species with birch being more prone to folding than aspen. Longitudinally flaking birch strands shows that an increase of strand length increased strand curl. Among the following variables, changing wood moisture content, changing the distance between counter knife edge to strand knife edge (edge distance), adjusting strand drying temperature, adjusting knife sharpness angle, and adjusting rake angle, increasing rake angle was the most effective way to reduce strand folding. The effect of wood drying temperature is worthy of further investigation. Making panels with furnish containing large amounts of folded strands resulted in panel delamination or low IB. Further investigation of the relationships between strand folding and panel properties is needed to develop a more complete understanding of the full impact of strand folding. These studies indicated that by combining higher wood temperature, larger counter knife angle and larger rake angle with certain microbevel, it will be possible to reduce strand folding, fines and energy consumption.

Abstract
La finition de meubles est traditionnellement réalisée à l’aide de produits liquides appliqués au pistolet à air. Les solvants qui assurent la fluidité du produit s’évaporent après l’application et les résines contenues dans le produit forment une couche protectrice de finition sur le bois. Afin d’accélérer la polymérisation du produit de finition, les solvants sont très volatiles et s’évaporent dans l’atmosphère. Le Conseil canadien des ministres de l’environnement a publié en 2004 des directives pour la réduction des émissions de composantes organiques volatiles (COV) provenant des opérations de finition des meubles en bois (le document est offert sur le site Internet www.ccme.ca). Ce document suggère à l’industrie du meuble de réduire les émissions de COV et il propose des limites. Le document est transmis aux ministères des provinces qui prendront la décision d’adopter les limites proposées. Les modifications des normes environnementales forceront l’industrie du meuble à réduire leurs émissions de COV dans l’atmosphère. Le remplacement des systèmes de finition traditionnels par des systèmes sans solvant est essentiel afin de respecter les futures limites d’émissions de COV. La technologie d’application, la méthode de durcissement et le produit de finition sont les trois éléments clés de l’effort de réduction des émissions. La finition à plat de composants de meubles avant assemblage permet l’application efficace de produits à base d’eau et de produits à durcissement par rayons ultra violets (UV). Le ratio de solide et le taux de récupération des produits de finition sont très élevés. L’application par rouleau (communément utilisée par l’industrie du plancher en bois) de ces produits est une solution qui respectera les nouvelles limites d’émissions de COV. La finition de produits tridimensionnels (pièces profilées, meubles assemblés) demande une application par pistolet. En utilisant un produit de finition liquide, la perte à l’application est importante et la récupération du produit difficile. Les produits en poudre sont utilisés avec succès dans l’industrie du métal mais est-il possible d’utiliser des poudres pour la finition du bois en conservant les performances des produits traditionnels? Il faut d’abord comprendre le principe de la finition en poudre pour évaluer le potentiel d’utilisation dans l’industrie des meubles en bois.

Abstract
Furniture is traditionally coated by one or more liquid products applied by an air pistol. The solvents used to ensure the fluidity of these products evaporate after application, and the resins contained within solidify to form a protective coating on the wood surface. In order to accelerate the polymerization of these products, the solvents are highly volatile and evaporate into the atmosphere. In 2004, the Canadian Council of Ministers of the Environment published directives (available at www.ccme.ca) for the reduction of volatile organic compound (VOC) emissions created during the finishing procedures of wood furniture. This document, which has been delivered to the provincial ministers who will decide whether to adopt its recommendations, suggests that the furniture industry could reduce VOC emissions and proposes limits. Modifications to environmental standards will force the furniture industry to reduce the volume of VOC emissions released into the atmosphere. It is essential that solvent-free wood-finishing systems replace traditional systems in order to respect the future VOC emission limits. The technology used for the application, the hardening method, and the product selected for the finish, include three key elements in the emissions reduction effort. The flat finishing technique used for furniture components before assembly allows for an efficient application of both water-based products and hardening products using UV rays. The solid content ratio and the recovery rate of the finishing products are quite high. The use of a roller to apply these products (as is commonly done in the wood flooring industry) is one solution that will respect the new VOC emission limits. The technique used for finishing three-dimensional products (multiprofile pieces, assembled furniture, etc.) requires application using a paint spraying device. By using liquid finishing products, the level of waste experienced during application is high, and the recuperation of the wasted product is difficult. Powder coatings have already been successfully used in the metal industry, but one question remains: is it possible to use powders to finish wood items and maintain the performance of traditional products? In order to answer this question and evaluate the use of powder coatings in the wood furniture industry, we need to understand the basic principles of powdered surface coatings.

Abstract
Whether you are drying 2 x 4 studs or high-quality hard maple for furniture stock, the range of available kiln systems has grown considerably over the past few years. Anyone considering the addition of new drying equipment would be well advised to consider all the options before making a final decision. Some drying systems offer the ability to dry products that were previously impossible to dry properly, or to achieve unprecedented product quality levels. Without considering all options up front, you could end up selecting a system that limits your ability to respond to current or future market opportunities.

Abstract
Le concept de production à valeur ajoutée (PVA) a été développé par l'industrie japonaise de l'automobile dans les années 1950. La PVA a succédé à l'approche de la production de masse introduite par Henry Ford au début des années 1920. James P. Womack, Daniel T. Jones et Daniel Ross, du Massachusetts Institute of Technology, ont réalisé une étude à la fin des années 1980 sur le futur de l’industrie automobile. Dans leur publication The Machine that Changed the World, ils ont nommé le concept Lean Production. Le but principal de la PVA est l’élimination totale du gaspillage. Toute activité n’ajoutant pas de valeur au produit est considérée comme un gaspillage. Dans le cycle manufacturier d’un produit, les activités sans valeur ajoutée peuvent occuper 95 % du temps. Les principaux types de gaspillage liés aux procédés manufacturiers sont :
Ressources excessives de production
Surproduction
Inventaire excessif
Attentes
Produits défectueux
Transports et manipulation
Dépenses en capital superflues
Manufacturing
Productivity
Process control

Abstract
The concept of “lean manufacturing” was first developed by the Japanese automotive industry in the 1950s. Lean manufacturing succeeded the "mass production" approach introduced by Henry Ford in the early 1920s. James P. Womack, Daniel T. Jones and Daniel Ross, of the Massachusetts Institute of Technology, carried out a study towards the end of the 1980s on the future of the automotive industry. In their publication, The Machine that Changed the World, they named the concept "lean production". Lean production was developed primarily to eliminate waste in every area of production. Any activity that does not add value to a product is considered wasteful. Zero value-added activities can take up 95% of a product’s manufacturing cycle. Some examples of these activities include:
Excessive production resources
Overproduction
Excess inventory
Waiting
Defective products
Shipping and handling
Superfluous capital expenses.

Abstract
Le marché de la production de composants de feuillus est présentement affecté par l’importation de composants à faible coût en provenance de l’Asie. L’automatisation industrielle est une option d’actualité visant à aider l’industrie de la deuxième transformation à contrer cette situation. L’intégration d’un système de détection de défauts est une démarche complexe et la sélection du système adéquat est d’autant plus compliquée. La présente étude propose une démarche d’évaluation des capacités des systèmes de détection de défauts et un outil d’aide à la décision permettant à l’industriel d’effectuer adéquatement la sélection d’un équipement. L’étude se limite à l’évaluation des systèmes de détection de défauts; les logiciels d’optimisation et les équipements de découpe ne sont pas analysés. La compréhension de l’origine et des caractéristiques des défauts à détecter ainsi que les définitions des capacités et limites théoriques des technologies de vision doivent initialement être maîtrisées. Un même échantillonnage présentant des défauts difficilement détectables par leur aspect ou leurs faibles dimensions est évalué par chacun des systèmes afin de permettre la comparaison. Les résultats démontrent que les systèmes évalués ne sont, à ce jour, capables de détecter l’ensemble des défauts pour la production de composants de bois franc. Un outil d’aide à la décision permet d’évoluer méthodiquement vers la sélection de l’équipement le plus approprié au besoin, ce processus de décision permet d’effectuer un choix éclairé en fonction de priorités et des attentes de l’industriel.
