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 ...

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...

The effect of copper/chrome/arsenic (CCA) treated timber on soil fungi
1981 - IRG/WP 1131
The aim of this investigation was to study the effect of CCA treated wood on the microflora of soil with particular reference to copper tolerant soft rot fungi. The IRG collaborative field experiment was designed to monitor the performance of a range of preservative treated hardwoods with particular reference to soft rot in CCA treated timber (Dickinson 1976) and site 33 of this experiment was use...

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...

Fire performance of the wood treated with retardant
2012 - IRG/WP 12-40591
To prepare the eco-friendly fire retardant wood, Japanese red pine (Pinus Densiflora), hemlock (Tsuga Heterophylla), and radiate pine (Pinus Radiata) were treated with inorganic chemicals, such as sodium silicate, ammonium phosphate, and ammonium boric acid. Different combination and concentration of those chemicals were injected by pressure treatment methods. The electron-beam treatment was used ...

Effect of electron beam irradiation on the fire retardant penetration into wood
2013 - IRG/WP 13-40642
Electron beam processing which can fast and easy change the nature of the material has received considerable attention recently. Studies using electron beam has been conducted in various fields and it has been applied in many industrial sectors. Electron beam has higher energy than other electromagnetic waves. It has excellent object permeability. It affects degradation of intermolecular cross-lin...

Field trials results of preservative treated ground contact stake conducted in Korea
2014 - IRG/WP 14-30640
The field trials results from Korea preservative treated ground contact stake are reported. There was two site which was in southern area(Anmeon) and east area (Jungsun) of Korea. The CUAZ, CCA and CBHDO preservatives were use in this study. The sapwood of Japanese red pine stake was treated with these preservatives according to Korea standard method and then installed in 2003. Every year the insp...

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...

Combustion and thermal characteristics of Korean wood species
2016 - IRG/WP 16-40727
This study examined the combustion and thermal characteristics of domestic woods in Korea. Wood was confirmed by a cone calorimeter according to the KS F ISO 5660-1 standard. The combustion properties of the wood were measured in terms of the heat release rate (HRR), total heat released (THR), mass lose rate (MLR), and ignition time (time to ignition; TTI). Also, the thermal properties were measur...

Evaluation of Decay Resistance of Copper-based Preservatives Treated-Wood exposed to different field test sites in Korea
2022 - IRG/WP 22-20679
In Korea, preservative treated wood is required to have a stamp on the surface which contains information such as wood species, use categories, and the company that treated the wood. Such stamping is necessary to safely and appropriately use the treated wood. Since majority of treated wood is being used outdoor environment, the treated wood must have efficacy against wood decay fungi or termite. I...

Evaluation of Decay Resistance for the Larch Wood Heat-treated with Superheated Steam
2022 - IRG/WP 22-40956
Heat-treatment of wood is a process that involves applying heat ranging 160–260°C to improve its physico-mechanical properties and resistance against wood rot fungi. The level of the changes in the wood properties by heat-treatment differs depending on the temperature and duration of heat-treatment, as well as the types of heat transfer media used for heat-treatment. The heat-treatment on wood ...
