List of wood-destroying fungi in Iran
1976 - IRG/WP 138
This list gives information on the wood-destroying fungi collected in the Iranian forests and from felled logs and boards in sawmills until now. They are mainly from the region of the Caspian Forests and from the climatically dry region between Teheran and Azarbaidjan, North Iran. It is understood, that this document may help to give more knowledge outside the country about the specific problems o...

Developements in the EEC on the regulation of wood preservatives
1993 - IRG/WP 93-50016
There is a wide variation in the regulation of wood preservatives within the EEC, ranging from product by product authorization under persticides legislation to controls via standards, or simple compliance with basic requirements on classification packaging and labelling. During the past two years the commission of the European Communitiesn has worked on a proposal concerning the placing on the ma...

Biological detoxification processes - A check list for assessments
1998 - IRG/WP 98-50120
The number of scientific publications on the biological purification of preservative treated wood implies that the biological treatment of wood wastes becomes more and more important. But an information about a successful industrial application is almost missing in all cases. Therefore the applicability of the proposed purification processes is often uncertain. The feasability of such a biological...

Observations on preservative penetration in poplar
1991 - IRG/WP 3662
In the course of studies on the CCA treatment and durability of poplar timber a zone of refractory wood at the sapwood/heartwood boundary was observed. Further studies were conducted to investigate the causes of this refractory behaviour. The initial results have suggested that the presence of lipid storage products in the ray tissue may lead to impermeability, either by directly blocking pits or ...

World list of wood preservative names
1980 - IRG/WP 387
The list contains names that have been collected by the author over many years and includes besides traditional wood preservatives, exterior wood finishes and preservative stains, and some preservative coatings. Generally, however, primers and paints have been deliberately excluded. The list includes also products that have been claimed as wood preservatives, as well as a few fire-retardant coatin...

List of insects intercepted in imported timbers in Italy
1983 - IRG/WP 1217
The list here reported has been derived from an investigation that the Wood Research Institute in Florence has been carrying out for some years, chiefly in sawmills, in order to verify the presence of wood insects in timbers coming from Europe, Africa, Asia, America (North, Central and South). Italy imports a great lot of timbers; during 1980, 1,320,000 m³ of logs and 495,000 m³ of sawnwoods hav...

List of fungi in soft-rot tests
1975 - IRG/WP 105
This list gives information on the terrestrial and marine species and strains of fungi tested for soft-rot ability in pure culture with data on their decay activity in untreated wood. An index of the timber species tested is added. The compilation is based on 1) the list of soft-rot fungi of the former OECD Group (Doc.No. 27/DAS/CSI/M/559), Oct. 1968, prepared by R. Rösch and W. Liese, 2) informa...

Overview of European discussions on Standardisation and list of proposed standards for WPC performance qualification
2006 - IRG/WP 06-20345
The standardisation is a driving force to promote the development of Wood Polymer Composites (WPC) by giving confidence to users and consumers. In Europe, the high interest of WPC require at this time a diffusion of information concerning the performances of WPC products. The WPC performances must be assessed according relevant standards in order to qualify the intrinsic properties of WPC (mechani...

Modelling hyphal growth of the bio-incising fungus Physisporinus vitreus
2010 - IRG/WP 10-10710
The white-rot fungus Physisporinus vitreus preferentially degrades the pit membranes of bordered pits in tracheids and subsequently enhances wood permeability. Thus, P. vitreus can be used to improve the uptake of wood preservatives and environmentally-benign wood modification substances. This process can be used to enhance the use and sustainability of native conifer wood species by the wood indu...

Copper Nanoparticles in Southern Pine Wood Treated with a Micronised Preservative: Nanodistribution of Copper in the Pit Membrane and Border of an Earlywood Bordered Pit
2011 - IRG/WP 11-30566
Copper nanoparticles can penetrate the cell walls of unlignified parenchyma cells in southern pine wood treated with a micronised wood preservative, but they are excluded from lignified tracheid walls. This paper extends these observations to include the cell wall layers of the bordered pit. Focused ion beam and ion milling were used to make an ultra-thin section of the cell wall layers of an earl...
