Accreditation: mutual benefits for research and industry
2010 - IRG/WP 10-20452
The wood preservation laboratory of the CIRAD had its first ISO 17025 accreditation from the COFRAC in 2006 for 5 standardized test procedures. The so called “first cycle” of its accreditation will be mid-2010. This laboratory is now accredited for 8 tests and is planning to increase the field of its quality management and accreditation. This poster describes how research projects, pre-normati...

Wood Preservation India; Current Scenario
2013 - IRG/WP 13-40630
This short note describes the present status of wood preservation research and its industrial application. Although good performing formulations have been developed by Indian research laboratories, industry has not tried to derive benefits from this development. Many unknown products are flooding the market for brush on applications with little benefit as the products have not been standardized....

Leaching of active components from preservative-treated timber - Ongoing research: Status after approx. 4 months’ out-door exposure
2003 - IRG/WP 03-20276
The Danish Technological Institute is together with manufacturers of active ingredients and formulators of wood preservatives running a project aiming at finding realistic leaching rates from preservative treated wood in hazard class 3 (above ground). The project is focussed on developing a field trial method for investigating leaching.
According to BPD hazard assessment has to be carried out f...

Qualifying ecotoxicity research on tropical hardwood leachates
1997 - IRG/WP 97-50096
Almost as a rule, quantification and identification of various types of environmental contamination is grounded on chemical evaluation principles. Yet for monitoring surface water pollution, aquatic bio-assays may provide a more direct way to assess the potential hazard of environmental samples. A battery of such tests is experienced onto leachates of tropical hardwoods used in ground and water co...

Comparison of the FRIM and forest research laboratory methods for screening of anti-sapstain formulations
1999 - IRG/WP 99-20170
Two laboratory methods for screening of anti-sapstain formulations were compared. The method adopted by the Forest Research Institute Malaysia (FRIM) involved 3 weeks assessment of rubberwood (Hevea brasiliensis) blocks, dipped in the candidate formulation and inoculated with mycelial/spore suspension of sapstain (Botryodiplodia theobromae) or decay (Schizophyllum commune) fungi, and incubated on ...

Introducing bamboos for their importance and conservation
2005 - IRG/WP 05-10546
Bamboo is a socio-economically, industrially and environmentally important forest and rural crop in Asia. It is an essential task for the people in this region to conserve the bamboos and preserve the bamboo products for their sustainable continuity. An earnest need for this task is to introduce a variety of important information on bamboos. In this research paper the botanical position, distribut...

Co-operative research project on L-joint testing. Sampling after 18 months exposure
1984 - IRG/WP 2233
In September 1983, Document No: IRG/WP/2208 was distributed giving guidance on sampling after 8 months exposure (due 1 December 1983 for those L-joints exposed on schedule on 1 April 1983), and including tables on which to record the test results. No major problems have been notified to Princes Risborough Laboratory concerning the sampling method. It is therefore proposed that the next sampling, a...

The need for realism in wood preservation research. A key address
1983 - IRG/WP 3254
The approval of a chemical for use as a timber preservative and the design of in service retention requirements represents an act linking fundamental research and commercial timber preservation. How difficult is it to translate figures generated through controlled experimentation into working specifications and how confident can we be in the methods used to provide such figures? The chairman of Wo...

Co-operative research project on L-joint testing. Progress report to March 1985
1985 - IRG/WP 2236
It was originally intended that each participant would expose L-joints in the main trial on 1 April 1983 with the first sampling at 8 months (1 December 1983) and the second sampling at 18 months (1 October 1984). In the event, some participants have had to vary this schedule. Results after the first sampling have been received from CTFT (8 months), BAM (12 months) and Sipad-IRC (8 months) and aft...

Some practical implications from recent research on the fixation of CCA preservatives
1975 - IRG/WP 358
The mechanism of fixation of CCA preservatives is briefly described. If the temperature is increased during the primary fixation period, the formation of intermediate fixation compounds is less extensive. The length of the primary fixation period is of practical interest. It is determined by preservative composition and concentration, temperature and wood species. Diagrams are given for Pinus sylv...

Research studies on infecting behaviour of Fomes fomentarius (L. ex FR) Fr. and its physical control in the wood yards of the Hyrcanian (Caspian) forests of Ira
1996 - IRG/WP 96-10179
Due to illegal cutting, girdling and ringbarking many damages of tinder fungus (Fomes fomentarius (L. ex Fr) Fr.) are seen on beech, poplar, oak and birch at Hyrcanian (Caspian) forests of Iran. The beeches (Fagus orientalis Lipsky) are damaged highly and the beech community of Fagetum are infected from 800 meter altitudes at Gorgan (East of Caspian forests) to 600 meters altitudes at Gilan (West ...

Wood preservation in Brazil
1978 - IRG/WP 3126
Wood preservation was stablished in Brazil by 1902 in order to provide treated sleepers for railways, since there was a shortage of durable hardwoods in area served by railways. The growing need of sleepers and poles together with the availability of Eucalyptus spp. contributed for the development of wood preservation. Many wood preservation plants started to be stablished in 1957, and in 1977 the...

Wood durability in the light of recent trends and research on the durability of building materials and components
2000 - IRG/WP 00-20195
Building-related research of today demonstrates a clear shift in focus from the design and production phases to usage and to the entire life time. A consequence is that the performance criteria of materials, components and of the entire building must be regarded over the life time rather than at the time of production or delivery. As one example can be mentioned the Building Construction Directive...

Computerised data acquisition and barcode technology - Examples of its application and use in wood preservation research
1992 - IRG/WP 92-2404
Experimental samples in wood preservation research are usually individually labelled with either some form of durable marking pen or more commonly with a stamped metal or plastic tag. The label must remain intact and legible for the duration of the experiment which, in the case of a field trial, can be many years. Preservative performance data have traditionally been recorded manually on a data sh...
