Environmental characterisation of retification process by-products (liquid and gaseous wastes)
2005 - IRG/WP 05-50224-10
In order to reduce environmental risks during the service life of the treated wood and to find new alternative developments on the durability of wood, some research and technology development have been made on thermal treatment. The retification process is one of these processes. The retification process induces chemical modification of the lignin and cellulosic components and modifies the intrins...

Determination of a fixation time of wood preservatives: A discussion paper
2010 - IRG/WP 10-20436
The intention of that paper is to initiate a discussion on the basis of a French method in combination with a German approach regarding the need of a method for the determination of a fixation time and especially to obtain input as well as ideas concerning a possible test design. Since no harmonised European approach exists up to now concerning the determination of a fixation time, CEN TC 38 (2009...

Laboratory evaluation of the natural durability and treatability of Cryptomeria japonica grown in La Reunion Island
2012 - IRG/WP 12-10772
The Japanese cedar Cryptomeria japonica is the main resource for timber construction in La Reunion Island, an overseas territory belonging to France. The natural durability of C. japonica originating from East-Asia has been considered so far as quite poor and the European standard EN 350-2 classifies this species ‘not durable’ with regard to its resistance to termites, xylophageous beetles and...

Study of the Factors Influencing the Treatability of Fir (Abies alba)
2018 - IRG/WP 18-40850
A study of some factors influencing the treatability of fir (Abies alba) was carried out in order to add better value to fir sawn timber coming from the Jura country, which is an abundant natural resource. In this part of France, fir wood as construction material is highly challenged by another softwood species, spruce Picea abies. In order to carefully assess the treatability of fir sapwood and h...

Monitoring of wood preservatives exposed to weathering: Extraction and analysis methods of organic biocides from treated wood and collected rain runoff
2020 - IRG/WP 20-30753
Weathering is the cause of numerous damages for outdoor joineries. Protection of wood using a preservative treatment covered with a coating is a process widely used to limit these damages. However, biocides from preservative treated wood are prone to degradation and leaching, having a direct influence on the joinery service life. This document deals with extraction and analytical methods for bioci...
