IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 4: Report of second inspection (12 months) in Australia
1979 - IRG/WP 448
Previous reports have presented full details of the treatment and installation of the test specimens in Sydney Harbour during December, 1977, and of the results of the first (6 months) inspection made during June, 1978. At the June inspection it was apparent that the plastic tubing used to make up the frames from which to suspend the specimens was inadequate for the job and not strong enough to su...

Ability of an acoustic inspection device to detect internal voids
in untreated pole sections
2002 - IRG/WP 02-20246
Detecting deterioration before substantial losses in material properties occur poses a major challenge to most wood users. While physical inspection techniques such as drilling or coring are useful, these methods can miss small pockets of damage and they lack the ability to detect early or incipient decay. The development of sonic test methodologies has created the potential for detecting change...

A rearing procedure for the house longhorn beetle Hylotrupes bajulus L
1973 - IRG/WP 228
The technique practised at the Princes Risborough Laboratory for culturing Hylotrupes bajulus is described. It is modified from methods previously suggested by German workers. A protein and vitamin enriched wood diet to accelerate larval growth is employed and larvae are subsequently given a period of cool storage to induce pupation. Adults are confined in groups with prepared surfaces for egg lay...

Electricity pole treatments - Wedding Bells State Forest. Inspection September 1983
1985 - IRG/WP 3334
A survey to study the extent of soft rot in hardwood poles in N.S.W. was commenced in 1975. The results of the survey, published in 1982, indicated that a number of factors contributed towards soft rot attack on poles in service. A detailed rest on pole treatments and maintenance procedures was established in 1976, at a site in Wedding Bells State Forest near Coffs Harbour. The site selected was k...

Preliminary testing of an improvised wood preservative mixture applied against dry wood beetles
1986 - IRG/WP 1308
An improvised wood preservative mixture was preliminarily tested in situ against some dry wood beetles which had infested structural timbers in a semi-finished building. The results obtained should encourage further research towards mobilizing/improvising locally available resources in the face of scarce standard wood preservatives, against the background of a dilemma in wood utilization in the de...

New methods for nondestructive inspection of timber in buildings
1995 - IRG/WP 95-20070
In these years older buildings are renewed in most European countries on a large scale, and new techniques are needed for both inspection and eradication of fungal attacks. Heat treatment as a means of eradicating the dry rot fungus has been used in Denmark during the last decade. This technique minimises the structural damage to the building, whilst at the same time reducing costs by up to 50%. T...

Experiences with supervision schemes for treated timber in Denmark
1984 - IRG/WP 3315
Since 1967 a voluntary supervision scheme for vacuum-pressure treatment was established in Denmark. In 1976 the Nordic Wood Preservation Council - NWPC - established a scheme based on wood preservation classes for treated timber as a joint technical standard valid in Denmark, Finland, Norway and Sweden. This paper deals with inspection results over 17 years for CCA treatment within our organizatio...

Isolation and identification of the fungal flora in treated wood. Revised technique
1977 - IRG/WP 159
At the 8th Annual Meeting in Wildhaus a paper was presented for discussion on the isolation of fungi from treated wood.·Since then work of this nature has been undertaken at Imperial College and as a result a revision of that document has been made and is presented here. The main alterations are: 1) To streamline the isolation procedure 2) Modification of the benomyl agar 3) The inclusion of a st...

Exposure of preservative treated wood to terrestrial microcosms, pure cultures of fungi and in the field
1997 - IRG/WP 97-20114
Small stakes (5x10x100 mm3) of treated and untreated Pinus sylvestris sapwood were exposed in terrestrial microcosms with different soils, two taken from test fields in Sweden, one soil from a conifer forest and one garden compost soil. Stakes of the same size were also exposed to pure cultures of the brown and white rot fungi, Postia placenta and Phanerochaete chrysosporium. After exposure, weigh...

Long-term preservation technology for a large-scale timber structure building in Japan
2001 - IRG/WP 01-40203
Several 1.000-year-old Buddhist temples and shrines built of wood are surviving in Nara, some areas of which are inscribed on the World Heritage List. These old buildings are indicative of excellent timber construction technology having existed in ancient Japan, though it is thought that such technology has not been handed down. This paper introduces one of large-scale wood buildings built in rece...

Quantification of creosote and fluoride in remedially-treated poles
1997 - IRG/WP 97-40097
Three creosoted transmission poles were put into service in 1961 and they were subsequently remedially-treated with a proprietary fluoride remedial paste formulation in 1981. The poles were removed from service in 1996 and their ground-contact regions were analysed for creosote and fluoride contents. It was found that the poles were undecayed. Creosote retentions decreased down the profiles of the...

The critical timing of inspections for field testing of natural durability
1994 - IRG/WP 94-20018
An overestimation of performance will almost always result if the condition of a specimen is considered to be attained at the precise time that an inspection is carried out. The time at which the condition is actually attained, referred to in this document as the "Condition time", is best considered to be halfway between two successive inspections. The requirement to obtain data that is relevant t...
