Literature survey on the permanence and distribution of salt-type wood preservatives
1969 - IRG/WP III 1B
The objective of this survey is generally to review some of the more important published work dealing with the distribution and permanence of salt-type waterborne wood preservatives in treated timber. The survey is limited to the major chrome-containing formulations and the classification system proposed by Becker (1964) has been adopted throughout.
CK - chromium, copper (copper, chrome); CKA - c...

Bibliography of organic solvent based wood preservatives
1971 - IRG/WP 38 E
This publication has as its objective the collection of the more important and more recent references dealing with solvent-based timber preservatives; these are often termed - sometimes wrongly - oil-borne preservatives or even organic wood preservatives. It is hoped that this review will stimulate more fundamental studies in the future in this field or on some of its aspects....

The growth and behaviour of Australian isolates of dry rot fungi, mainly Serpula lacrymans (Schum. ex Fr.) S.F. Gray. A comparision with the world literature
1983 - IRG/WP 1190
In Australia Serpula lacrymans occupies a rather unique environment, being restricted to growth within basal regions of buildings containing masonry. Its rate of timber attack in these situations appears to be far faster than that experienced in other parts of the world. Therefore the question arises as to how Australian isolates (particularly 16508 which has become a "standard" test fungus for so...

Wood structure in relation to excessive absorption - a literature survey
1971 - IRG/WP 300
This literature study, composed in connection with 'the structure of wood in relation to the excessive absorption', started from the idea that the subject only could be dealt with successfully if the structure was taken into account in relation to a normal absorption pattern in so far as this knowledge can enlighten the understanding of the abnormal situation. The normal penetrat...

Note and literature survey on the "Eucalyptus borer" Phoracantha semipunctata F. (Col.; Cerambycidae), a pest in between forest and wood
1984 - IRG/WP 1228
In the Eucalyptus-forests of Huelva, Spain, Phoracantha semipunctata appears as a severe forest-pest fatal to trees impaired by drought. The population snowballed in two and a half years, millions of larvae reduce the value of wood to "papermill-quality''. One of the intentions of the paper is to collect knowledge for help and cure. A literature survey forms the main part of the ...

A survey of factors affecting decay resistance of wood modified with acetic anhydride
2012 - IRG/WP 12-40594
From the range of information published, acetylation appears well suited to provide adequate protection against biological attack for materials derived from typically non-durable wood species. Acetylated wood is now commercially available both in Europe and in the USA. But still there are a lot of unanswered questions related to fungal decay mechanisms in acetylated wood. The paper summarize exist...

Soft rot in CCA-treated utility poles in Sweden
1989 - IRG/WP 1398
Soft rot investigations of CCA-treated utility poles (Pinus sylvestris L.) have been conducted throughout large parts of Sweden during 1974-1985. The investigation included 179 utility poles of the State Power Board which had been used for 10-18 years in the different administrative regions from northern to southern Sweden. In addition, 193 telephone poles from the Östersund area and 218 from the...

The status of Anobium punctatum and Hylotrupes bajulus in buildings in the United Kingdom
1993 - IRG/WP 93-10039
Anobium punctatum and Hylotrupes bajulus are the two most significant insect pests of structural timber in the UK. This paper describes the results to date from two separate surveys in the UK carried out by the BRE in collaboration with remedial treatment companies, local authorities and building societies to establish the incidence and status of these insects with respect to geographical location...

Termite standards questionnaire survey. Second Report
1989 - IRG/WP 1395
Information contained in replies received from IRG members responding to the survey continue to be summarised. Again, highlighted in this second report are the major termite species in the various zoogeographical regions, their damage ranking to timber-in-service, the chemicals used in control methods, and the status of the termite standards in the respondent countries....

Survey of conditioning treatment practices in India
1978 - IRG/WP 3127
India has 75.3 million hectares (ie about 24% of total land area) under forests out of which the area of productive forests, from which industrial wood is available, is about 60 million ha. The Task Force on Forest Resources Survey has tentatively estimated that the total growing stock in Indian Forests is 24,000 million cubic metres (m³). The total recorded production of wood in the country is r...

A survey to assess the current and future usage of timber in British port structures
1998 - IRG/WP 98-10247
Port engineers responsible for 30 British ports were surveyed by questionnaire or interview to establish current and prospective usage of timber in those ports. The ports surveyed account for about 25% of total cargo handled annually in Britain and being located all around the British mainland, were considered to form a representative sample. The survey identified the hardwoods and softwoods in us...

Moulds and indoor climate in Denmark
2003 - IRG/WP 03-10488
Just like in many other countries after the oil crisis in 1972 Danish houses were tightened with the result that the relative air humidity rose considerably. The Ministry of Energy also demanded a lowering of the indoor temperature from 25°C to 20°C with the result that the relative air humidity rose even more. According to the latest survey 10% of Danish buildings are infected with moulds. Moul...

Fumigation as a remedial treatment: A review of North American literature
1983 - IRG/WP 3253
The development of the use of fumigants for eliminating decay in timber and roundwood in North America is reviewed. Initial experiments on oak wilt identified volatile chemicals which eradicated decay in roundwood. Subsequently, extensive experimentation on Douglas-fir poles in service showed that treatment with chloropicrin eliminated internal decay for more than ten years. Vorlex was also quite ...

Report of an investigation of damage by wood ants in buildings in Sweden
1976 - IRG/WP 148
Wood ants in buildings occur everywhere in Sweden, particularly in maritime districts and in vicinity of larger lakes. The damage caused by Camponotus herculeanus does not differ from that caused by Camponotus ligniperda. The former occurs in all Sweden, the latter only in southern Sweden. The damage is to be found almost exclusively in dwelling houses (week-end cabins and "all-the-year round" hou...

This paper reports the results of a survey of Australian commercial beekeepers working 200 or more hives in June/July 1985. Nine hundred and forty seven apiarists were asked to participate and to provide information on their wood preservation methods, painting procedures and maintenance of bee boxes. Three hundred and eighty-four apiarists returned completed questionnaires (41%). The main wood pre...

Positive dosage response of CCA in hardwood power poles to soft rot indicated from New South Wales soft rot survey dat
1983 - IRG/WP 3233
Experience and observation have shown that retentions of less than 16 kg/m³ in the sapwood of individual hardwood poles are unlikely to delay its deterioration sufficiently to ensure an economic performance in some instances. The higher retentions of current practice should do so subject to adequate inspection and maintenance. Increases in retentions requirements up to 35 kg/m³ more or less, dep...

Survey of maintenance management of a residence
2001 - IRG/WP 01-10405
The following points were clarified from the responses to the questionnaire. Termite damage was most common in the bathroom, washroom, and entrance, in that order. Termite damage was most commonly found beneath floors, followed by floor surfaces, and inside walls, in that order. Damage in framing was minimal. Damage in all structural components was most common in the Kyushu region, with the most s...

The evaluation of the occurrence of soft rot in creosoted wooden poles
1988 - IRG/WP 1368
The occurrence of soft rot decay in creosoted wooden poles for overhead power lines was investigated by collection of field samples, their subsequent microscopic examination and statistical analysis of the data collected. Examination of samples collected from 296 poles revealed that approximately 15% of the pole population studied (Eastern Electricity Board) showed the presence of soft rot decay. ...
