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...

Effect of protective additives on leachability and efficacy of borate treated wood
2002 - IRG/WP 02-30290
Borate preservatives have been used extensively in many countries as an effective means for protecting wood against fungal and insect attack especially in interior environments. Under exterior conditions, borate compounds have a main disadvantage as they can be leached from
treated wood as a result of their water solubility. In this study, we compared the potential of different additives for re...

Surface Barriers for Protection of Culture and Heritage Wooden Objects from Insect Attack
2004 - IRG/WP 04-40286
Anoxic treatment is an environment friendly procedure for eradication of wood boring insects in wooden objects of cultural and historical heritage. However, after the anoxic treatment, wooden antiques remain susceptible to further insect attacks. Possible protection against insects could be provided by the so-called post-repression protective barriers. Potential coating materials for such barriers...

Evaluation of some polyurethanes as protective marine coatings for wood
1985 - IRG/WP 4115
Several polyurethane formulations were evaluated in the marine environment as possible replacements for Irish felt used on U.S. Navy minesweepers as a marine borer barrier between the main wooden hull and an outer, wooden sheathing which covers it. Pine panels coated with the candidate materials were tightly juxtaposed with untreated pine baitwood to simulate the hull/sheathing configuration, the ...

Evaluation of the protective means of some wood preservatives by means of accelerated tests
1973 - IRG/WP 232
In site conditions of the eastern site in the forest-steppe part of the Krasnovarsk region, the relative effectiveness of a series of wood preservatives was obtained by means of field tests. To obtain a more accurate evaluation of the protective qualities of these accelerated tests were carried out in laboratory conditions. In 9 boxes filled with non-sterile soil taken from the site, 72 samples of...

Enhancing the Performance of Transparent Coatings by UV Protective Pre-treatments
2006 - IRG/WP 06-30399
Most industry observers anticipate a change from copper-based preservatives to metal-free combinations of organics for residential treated wood products in North America within the next one to five years. While the chromium copper provide considerable protection against UV, metal-free formulations will need UV protection in the form of additives or coatings. While transparent coatings can be made ...

Protection of a low-density mangrove timber species gewa (Excoecaria agallocha) through preparation of particleboard – An Assessment
2006 - IRG/WP 06-40348
It is now well established that the conversion of low-density and low-cost timbers into laminated, composite and densified form is an alternative of wood protection by means of wood preservatives. Once only the timber species gewa (Excoecaria agallocha) was used for manufacturing newsprint paper in Bangladesh, which is not continued today. The feasibility of commercial production of particleboard ...

Some textile auxiliaries as wood protective agents
2007 - IRG/WP 07-30417
This study evaluated some textile auxiliaries applicable for wood protection. Commercial alkoxysilane quarternary ammonium formulation and fluorocarbon based water-oil repellent were tested for their ability to provide hydrophobicity and antifungal effect to solid wood samples. Scots pine (Pinus sylvestris L.) sapwood samples were impregnated with 25, 50 and 100 % concentrations of the above menti...

Protective Levels of Borates in timber Foundation Piles 5 – 18 Years after In-situ Remedial Treatment in Areas with Wet Clay Ground Conditions. The Jerbor and Eurobor Protocol, Part 1.
2011 - IRG/WP 11-30571
Timber has been used as foundation piles and grillages for decades or even centuries. Since the late 1970s a method for investigate, analyze and treat building timber foundations in soft clay grounds against decay fungus with a biocide have been developed and used by the late professor Allan Jerbo. Settling of buildings in soft clay grounds is continuously monitored and if damages to the building ...

Protective nanoparticle coating reducing water absorption of wood species
2012 - IRG/WP 12-40614
Nanoparticle coatings were deposited onto different tropical wood samples for controlling the surface hydrophobicity. The styrene(maleimide) nanoparticles were synthesized in aqueous dispersions under pure conditions or in combination with 70 wt.-% palm oil. A first evaluation of the non-coated wood surfaces indicates a high dependence between the water contact angles, the average surface roughnes...
