Proposal for co-operative work. Testing the ability of accidentally introduced tropical insects to survive the cold season in Europe
1976 - IRG/WP 155
By hibernation-experiments in the past it was found that not only the low temperatures may become fatal by freezing. In some experiments we found indications that larvae died by starvation. For example Lyctus africanus-larvae did so in some years with a cold winter (mean above 0°C). If you like to take starvation as a reason for death into account it may be useful to withdraw pieces of infested w...

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...

Safe application of copper-chrome-arsenate preservatives
1975 - IRG/WP 377
All wood preservatives contain biologically active substances and must, by design, be in some measure toxic to man. There is nothing fundamentally difficult, however, about using a wood preservative with complete safety. It depends on knowing the risks to health and/or the environment, which the preservative may present, and planning application accordingly. In this paper we examine these and othe...

Introduction of plank-built catamarans along the north coast of Andhra Pradesh, India – A development of recent origin
2003 - IRG/WP 03-10483
Hitherto, the most versatile fishing craft of the poor traditional Indian fishermen - the catamaran is made of solid timber logs of a few selected species of broad-leaved softwoods. Of late, the fishermen find it difficult to get these conventional varieties of timber chiefly because of three reasons, a) scarcity of commodity, b) prohibitive costs and c) competition from match and veneer industri...

The dry rot fungus (Serpula lacrymans) in nature and its history of introduction into buildings
1999 - IRG/WP 99-10300
For many years the True dry rot fungus (Serpula lacrymans (Wulf.: Fr.)Schroet.) has exclusively been found in buildings. That is why it is called the True dry rot fungus. The origin of the fungus has always been a mystery, but a wild ancestor must have occured. In the literature there is some information about finds of Serpula lacrymans in nature, however it is difficult to distinguish it from the...

Accidental mold/termite testing of high density fiberboard (HDF) treated with borates and N’N-naphthaloylhydroxylamine (NHA)
2003 - IRG/WP 03-10462
High density fibreboard (HDF) was made from beech and pine furnish (50:50) and treated with boric acid (0.1-3%), borax (0.1-3%) or N'-N-(1,8-naphthalyl) hydroxylamine (NHA) (0.1-1%) prior to gluing with urea formaldehyde (UF) resin in order to determine resistance to Eastern subterranean termites (Reticulitermes flavipes Kollar), the most economically important termite species in North Am...

Preventing the introduction of Xylosandrus crassiusculus by dipping green lumber in insecticides prior to shipment
2007 - IRG/WP 07-40370
Xylosandrus crassiusculus, an ambrosia beetle native to Asia and Africa, was introduced into the southeastern United States in 1974. Since that time, this species has substantially expanded its range, causing damage to native ecosystems and healthy nursery stock. This species was found in The Dalles, Oregon in 2004, indicating that it is not limited to sub-tropical environments. This introducti...

Brief introduction of a research project on the wood materials from an ancient Byzantine port unearthed during drilling for underground rail tunnel in Istanbul
2008 - IRG/WP 08-10641
A research project has been recently started to evaluate some properties of wooden materials from the biggest port of ancient times called Port of Theodosius I in Istanbul, Turkey. The ruins of the ancient Byzantine port during the excavations were recently uncovered in the Yenikapi site where an underground rail tunnel construction has been in progress in Istanbul. The wooden objects unearthed fr...

Moisture distribution in glulam beams with natural cracks observed with CT Scanning before and after rain
2013 - IRG/WP 13-20534
The way cracks in outdoor wooden constructions affect durability is an interesting topic, since a certain amount of cracks can always be found naturally in wood and glued laminated wood. The question in this was, can cracks lead water into the wood and thereby increase the risk for decay and reduce strength and service life. Moisture balance, i.e., water absorption and water distribution were stud...
Introduction of the COST FP 1303 Cooperative Performance Test
2015 - IRG/WP 15-20567
COST Action FP 1303 “Performance of bio-based building materials” successfully started in October 2013 and an ambitious program was set up for the four year programme. COST Actions provide an excellent opportunity for collaborative research, e.g. in the frame of Round Robin tests. The idea of this respective test was to distribute a fairly simple test set up to as many places in Europe as poss...

Introduction to the project ‘Deterioration and decay of wooden cultural heritage in Arctic and Alpine environments’ (ArcticAlpineDecay)
2022 - IRG/WP 22-10997
The Arctic is already affected by climate change, and this is expected to accelerate over the coming decades. Alpine regions in Norway are projected to face similar challenges. Current knowledge on Norwegian wooden cultural heritage in Arctic and Alpine regions is scattered and contains significant knowledge gaps. Historically, - scientists, sectorial governance, tourist trade and commerce have ma...

Brief introduction to a research project on preparations of various paste formulations from boron, fluoride and copper for supplemental treatments
2022 - IRG/WP 22-30759
Wood preservatives to be used for supplemental purposes are present in various forms such as powders, liquids, rods, pastes, or gels. Boron compounds have been receiving a lot of attention in supplemental treatments since they have good mobility in wood. Application of boron compounds via internal treatments is vital to stop decay to be occurred inside the wood since large wood elements are too th...
