GDR3544 “Science du Bois” - Academic and Industrial French Partnerships on Wood Science
2019 - IRG/WP 19-50362
The wood sciences are currently practiced by a very diverse community of disciplines, themes and institutional contexts of different actors. The Research Group in Wood Sciences (GDR3544 "Sciences du Bois") was created in 2012 by the National Center for Scientific Research (CNRS), and renewed from 2016 to 2020. The objectives of GDR " Science du Bois " are to manage the coordination of wood scienc...

Report and recommendations of the National Termite Workshop held in Melbourne on the 17 April 2002.
2003 - IRG/WP 03-10478
There are two parts to this Report. Part One summaries the outcomes of an industry workshop organised to better scope the subterranean termite problem, identify knowledge gaps including R&D gaps and identifying strategies including cost-effective co-ordination mechanisms for addressing the issue. Part Two is a brief review of the current state of knowledge on subterranean termites of economic ...

Sustainability Through New Technologies for Enhanced Wood Durability. COST Action E37 – A New Action in the Forestry Domain
2004 - IRG/WP 04-40293
The main overall objective of the action is to concentrate on the contribution of wood durability on the sustainability through the development of systems for quality assurance and perfoamance of modified wood and wood products as alternatives to wood treated with traditional preservatives. By this means it seeks to improve and consequently increase the cost-effective use of sustainably produced E...

The new National Directive on wood preservation in the Netherlands
1998 - IRG/WP 98-50101-03
In the Netherlands the major part of treated timber is sold under the KOMO-certificate. The National Directive for vacuum pressure treated timber on which certification is based, is currently being revised. The new National Directive will contain a code of good practice including maximum leaching figures. It incorporates quality requirements for treated timber, existing legislative requirements an...

Modified Wood – Methods, testing and applications: Outcomes of the EU-Thematic Network
2003 - IRG/WP 03-40268
In the last decade, interest in the development of wood modification systems has increased in Europe. Alongside several industrial initiatives for heat treatments, there have also been scaling up and pilot plant projects for chemical wood modification. Between 2000 and 2003, the European Commission funded the "Thematic Network on Wood Modification". This paper will feature the modification process...

Dutch national environmental policy strategy (NMP): Implications throughout the life cycle of treated timber and for the Dutch preservation industry
1993 - IRG/WP 93-50001-31
All overview of relevant environmental legislation and instruments for control is given for each stage of the life cycle of treated timber. Recent policy in the Netherlands has been focused around the "National Environmental Policy Strategy", in which a general policy with regard to reduction of pollution to the air, soil and water is described. The principle is one of an "Integrated Chain of Cont...

Determination of corrosive effect of liquid wood preservatives to metals – First experiences with a National Standard which is in revision
2006 - IRG/WP 06-20321
The development of standards is an essential tool to characterise different kind of materials and products. An important aspect during the development of a new product is to check the corrosion behaviour with other materials. Corrosion can cause several problems like pitting corrosion. Consequently the knowledge concerning the corrosive effect of liquid wood preservatives is important due to the s...

Test methods for modifies wood: The EU-Thematic network approach
2002 - IRG/WP 02-20255
The last decade wood modification systems have become new wood treatment methods in Europe. Alongside several industrial initiatives for heat treatments also scaling up and pilot plant projects for chemical wood modification have recently been carried out. In 2000 an initiative to create a network related to these new developments was supported by the European Commission. Within the work proposed ...

COST Action E37. Sustainability Through New Technologies For Enhanced Wood Durability -
2008 - IRG/WP 08-40417
The main overall objective of the Action was to concentrate on the contribution of wood durability to sustainability through the development of systems for quality assurance and performance classification of modified wood and wood products as alternatives to wood treated with traditional preservatives. By this means it seeked to improve and consequently to increase the cost-effective use of compon...

Use of Internal Remedial Treatment to Extend Wood Life at the Fort Vancouver National Historic Site
2010 - IRG/WP 10-30525
The condition of wood in a reconstructed fur trading fort was assessed over a 30 year period. Poor initial treatment had resulted in the development of extensive early decay. While supplemental treatment with chloropicrin and methylisothiocyanate had arrested the attack, the results suggested that remedial treatments were unable to completely overcome the initial problems associated with treatmen...

Wood protection in the Sierra Nevada National Park, Venezuela
2012 - IRG/WP 12-50290
The use of wood without the respective protection inevitably leads to its replacement. When this wood is used in a national park call attention to public opinion because the consequences generated by the very short life service, and replacement is required, means more wood not preserved, rapidly deteriorated in a constant repeated cycle. This becomes an environmental problem, especially when the ...

An assessment of soft rot in preservative-treated poles in two test sites and two network areas in New South Wales
2013 - IRG/WP 13-10801
This document presents an extended summary of recent investigations into soft rot attack of preservative treated power poles from the re-inspection of samples selected from two field sites and two in-service trials located in New South Wales, Australia. The in-ground sapwood of selected poles was assessed by probing and, after core sampling, by microscopy to determine the severity and extent of s...

Building solid foundations to support market growth of preserved wood in the UK – treatment quality, product approval and the largest national field trial of preservative treated wood in 50 years
2015 - IRG/WP 15-30662
The Wood Protection Association (WPA) has just commissioned Britain’s largest ever durability trial of home grown timber, having contracted Building Research Establishment (BRE) to conduct a long term controlled field trial of sawn and pressure treated British Softwood posts at two sites with differing soil conditions. This large scale Field Trial is the last of an innovative and substantial thr...

Visual assessment of longitudinal wheel timbers and assessing the feasibility of extending wheel timber service life in the UK railway network
2019 - IRG/WP 19-20651
Timber has been a versatile building material for centuries and during the start of the Railway Age in the nineteenth century it was in considerable demand for use in the railway network, particularly bridge building. Timber is still in service and widely used throughout the UK railway network. The resilience and favourable strength to weight ratio and its relative ease of fabrication make it an...

Towards a microactuator-sensing network for the structural health monitoring of wood
2023 - IRG/WP 23-50380
Timber structures decay over time with degradation in their structural integrity. Changing environmental conditions, varying loads, exposure to moisture or insect attacks lead to changes in their vibrational response behaviour. Here we present a low-cost device used as a triggered exciter to enable the monitoring of the structural integrity of timber bearers or even power poles in electricity netw...
