Proposed method for out-of-ground contact trials of exterior joinery protection systems
1981 - IRG/WP 2157
Methods for testing the efficacy of preservative treatments for exterior joinery are described using the format of a European Standard. Commercially used treatments applied to jointed test units (L-joints) which are then protected by conventional finishes are exposed to normal outdoor hazards out of ground contact. Assessment is made a) by determining eventual failure through decay and b) by destr...

Thermal treatment of wood: European Processes and their background
2002 - IRG/WP 02-40241
Recent efforts on thermal treatment of wood lead to the development of several processes introduced to the European market during the last few years. The total production capacity of heat treated wood in 2001 is estimated as approx. 165.000 m3. In the paper the different heat processes are presented. The general technology as well as scientific data on the chemical transformation of the cell wall ...

Bioaccumulation of pentachlorophenol in rainbow trout and zebra fish muscles
1986 - IRG/WP 3372
The bioaccumulation of pentachlorophenol in Rainbow Trout and Zebra fish has been evaluated by partition coefficient n-octanol/water determination at ph 7 and measured in vivo according to the OECD guidelines and the European directive 79/831/EEC. The obtained results confirm the low bioaccumulation potential of this product in aquatic organims....

Interspecific variability of European oak durability against white rot fungi (Coriolus versicolor): Comparison between sessile oak and peduncle oak (Quercus petraea and Quercus robur)
2001 - IRG/WP 01-10393
The knowledge of wood natural durability against biologic predators enable its external use. The resistance of European oak wood was reported like durable according to the EN 350-2. However, some individuals may contain high durable wood. Our research was focused to understand this variability in oak population that represent the first french species (4.1 millions of ha). Natural durability of Eur...

CEN Draft (38 N 460E) Standard: Test method for determining the protective effectiveness of a preservative in the marine environment
1986 - IRG/WP 4132
This European Standard describes a marine test method which provides a basis for asseasing the effectiveness of a wood preservative used to prevent attack of timber in sea-water by marine borers. The method is only suitable for testing preservatives which are intended to prevent attack by marine wood boring organisms of treated timber for use in more or less permanent contact with sea-water. It is...

Conforming to european standards for preservative-treated timber: Specifying with confidence
2000 - IRG/WP 00-20194
A four-year collaborative study between four industrial partners and BRE has assessed timber treated by current UK industrial practices in the light of current European Standards. Data were collected for CCA and creosote treated timber components, and compared with the requirements laid out in EN351-1 and -2. A number of difficulties were encountered that have been described in previous IRG papers...

Wood preservation in East European countries
1989 - IRG/WP 3527
The paper discusses the main problems of wood preservation in Bulgaria, Czechoslovakia, German DR, Hungary, Poland, Rumania and the USSR. The main types of wood preservatives produced have been presented, as well as the state of standarization to test their properties. There have been considered methods of wood treatment in use and application range of treated wood....

Draft Business Plan of CEN/TC 38 - Durability of wood and wood-based products - Introduction
2000 - IRG/WP 00-20207
CEN Technical Committees and Business Planning. The extension of formal business planning to CEN Technical Committees (CEN/TCs) is an important measure which forms part of a major review of business processes (known as 'Optimization'). The aim is to align the CEN work programme with expressed market needs and to ensure the adequate resourcing of projects through their development...

Current models used by the European Health Authorities to evaluate the volatilization of active ingredients from treated wood used inside dwellings. A case study: Volatilization of azaconazole and propiconazole from treated wood
1990 - IRG/WP 3565
The use of wood preservatives inside houses may result in measurable aerial concentrations of active ingredients. These airborne contaminants may be inhaled by the inhabitants over periods lasting from a couple of days to several months. To assess the potential health hazard of preservative residues in the air, various risk-assessment models have been worked out. Three schemes, currently used by t...

Comparison between the Hylotrupes bajulus strains of different European laboratories
1980 - IRG/WP 1118
In several European countries, wood preservatives of the same formulation are subjected for the quality label to particular tests according to standards established by the CEN. The different laboratories which carry out these tests have had their cultures for many years. The insects are kept in optimal nutritional and climatic conditions and have always mated amongst themselves. On the one hand, e...

Incursion of Hylotrupes bajulus Linnaeus (European House Borer) into Western Australia
2005 - IRG/WP 05-10558
In January 2004, an adult Hylotrupes bajulus Linnaeus was detected emerging from a beam of Pinus pinaster in a house in Perth, Western Australia. The timber had been locally grown and milled. Surveys to define the extent of the infestation show it is restricted to dead pine trees in 28 sites around Perth. The biological and economic feasibility of eradication is being assessed. Since about 2001, k...

Natural durability of European wood species for exterior use above ground
2003 - IRG/WP 03-10499
The main interest in using more timber for exterior constructions is to protect the environment, where wood is considered an environmentally friendly material. However, chemicals for wood protection are getting more and more restricted, consequently, the focus on the natural durability of wood is increased. Good, well-documented data on the durability of wood species in ground contact exist, which...
