Biocides - Efficacy assessment and doses for wood preservatives (product type 8). Local/geographical aspects. Termite control as case study
1999 - IRG/WP 99-20181
Currently, the efficacy of a wood preservative, as biocidal product type 8, is assessed as a ‚critical value' (CV), an efficient dose (retention in wood at a given depth of penetration). CVs are planned to be adapted for exposure to basic target organisms (5 hazard classes) and additional requirements concerning the occurrence of local target organisms in relation with climate, building...

The implementation of restrictions on the use of arsenic and chromium based wood preservatives in Sweden
1995 - IRG/WP 95-50062
In 1992 the Swedish National Chemicals Inspectorate introduced restrictions on the use of wood treated with arsenic and/or chromium based wood preservatives. Such wood is now in principle only allowed for use in ground contact or in water. These restrictions have had considerable influence on the use of wood preservatives for sawn timber for the Swedish domestic market. Thus only 35% of the preser...

Development and Implementation of a DNA – RFLP Database for Wood Decay and Wood Associated Fungi
2004 - IRG/WP 04-10527
We are developing Restriction Fragment Length Polymorphism (RFLP) and Internal Transcribed Spacer (ITS) sequence databases for wood decay basidiomycetes and other fungi associated with wood. These databases currently house information for 39 fungal species consisting of 9 brown-rot basidiomycetes, 12 white rot basidiomycetes, 1 soft rot, 1 stain fungi, and 16 molds or other ascomycetes or imperfe...

A review of the implementation of results-based standards for preservative treated timber
1999 - IRG/WP 99-20156
European standards for the specification of preservative treated timber are written in terms of the results achieved in the commodity by the treatment process. This is described in terms of penetration and retention of preservative. Results from a study on the commercial application of this approach in the UK show the difficulties associated with applying the new European standards; particularly w...

Non agricultural biocide directive. Practical proposals of implementation in the case where biocides are wood preservatives
1995 - IRG/WP 95-50040-24
This project of non-agricultural biocide directive has currently an extremely wide scope of pre-marketing authorization of substances and preparations used in numerous applications, other than agricultural. Elaborated on the 86/414/EEC model of the phytopharmaceutical product directive, the "NAB" draft directive aims to cover situations as different as plant or wood protection: in the case of plan...

The UK termite eradication programme: Justification and implementation
2000 - IRG/WP 00-10373
In May 1998, an established infestation of subterranean termites (Reticulitermes lucifugus subsp. grassei) was found in a semi-rural, coastal setting in Saunton, North Devon. Surveys and monitoring revealed a discrete, highly localised infestation extending over some 2400 square metres. There is some evidence that the termites were imported accidentally possibly more than 30 years previously. With...

Implementation of a Quality Assurance System for thermally modified timber (TMT) by the Association of Central European TMT-Producers
2011 - IRG/WP 11-40558
Due to increasing market shares of thermally modified timber (TMT) in Europe, a working group of ten central European TMT manufacturers (TMT-WG) was founded in 2010 to cover public relations and marketing activities. Since the present level of product testing and property declaration was not satisfying, a “task group TMT-quality” was put into action in 2010 to develop a comprehensive quality a...

The overview of ISPM 15 implementation in Croatian wood-working companies
2011 - IRG/WP 11-30576
Croatia is a small European county, but in the same time a great country according to it’s tradition in the forestry and wood working industry. However, around 48% of it’s territory is afforested. As the export is one of the main directions in the Croatian development conception, the production and distribution of wood package intended for the international trade, is one of the most important ...

Japanese traditional wooden building construction project in Bangkok - Part 1 Project outline, building implementation and effects
2023 - IRG/WP 23-40992
The purpose of this project is to build new ways to utilize wooden resources in Japan. Japan's forestry industry is in decline despite its abundant forest resources due to a lack of successors and other reasons. Meanwhile, in Southeast Asian countries, reinforced concrete houses, which are not suited to the climate, are on the rise due to a lack of wood and technology. To solve these problems in b...
