Wood preservation in Turkey
1982 - IRG/WP 3216
The report reviews the forestry potential of Turkey and also the historical background of wood preservation in the country. The wood preservation industry in Turkey is mainly concentrated on the treatment of poles and railway sleepers. There is no official body responsible for wood preservation activities, and therefore its promotion depends mainly on the voluntary research efforts carried out by ...

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 9: Report of third inspection (2 years) in Italy
1980 - IRG/WP 461
The wood samples were submerged in the sea at Follonica, Italy, in April 1977. Follonica, latitudine 42°55' North and longitude 10°45' East, is situated on the Tyrrhenian sea. The recorded temperature varies between 13°C to 25°C, salinity 37-38% and pH about 8. The inspections were carried out after 6 months (10/1977), 1 year (4/1978) and 2 years (4/1979)....

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 7: Second report on the samples in Papua New Guinea
1980 - IRG/WP 459
This report presents the findings to date regarding specimens installed in Papua New Guinea, as part of a world-wide marine trial of certain timbers treated with CCA or CCB preservatives. The details of the trial are set out in document number IRG/WP/414. The report discusses the findings in the context of the conditions prevailing at the trial site and of the properties of the trial timbers. The ...

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 20: Report on the inspection of specimens at Sekondi, Ghana after 48 months
1985 - IRG/WP 4116
The results of the second inspection of CCA- and CCB-treated test panels exposed at Sekondi, Ghana, in June 1980, are presented. The panels of Pinus sylvestris treated with 3% CCA are stil unattacked after 48 months. Panels treated with 10% CCA and still in test (Fagus sylvatica, Pinus sylvestris and Alstonia scholaris) are still free of attack. Locol species treated with 3% CCB have all been dest...

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...

Chemical analyses of IRG/COIPM INTERNATIONAL MARINE TEST (to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water) samples
1987 - IRG/WP 4114
Chemical analysis of CCA and CCB treated timber was carried out after exposure at tropical and temperate marine sites. Results indicated that losses of all elements had occurred. In particular, losses of boron were severe. Arsenic and copper were also lost. The chromium components in both formulations was the most dominant metal remaining. The results suggest that chromium modification was importa...

Soft rot tests
1983 - IRG/WP 2206
At the IRG meeting in Turkey it was proposed that developments in testing preservative-treated wood in unsterile soil according to techniques variously described as "fungus cellar", "soil-bed", or "accelerated field simulation" be considered along with conventional laboratory procedures as the basis for a standard test. Before formulating any co-operative test programme it is essential to examine ...

Issues Facing Wood Preservation in New Zealand Today
2003 - IRG/WP 03-30326
In New Zealand, the three major issues facing the wood preservation industry today are:
Extension of use of LOSP preservatives, chiefly tributyltin naphthenate, for treatment of products in Hazard Class H3 exposed to the weather for which LOSP have not been traditionally used. Concerns have been expressed about the long-term durability of such products.
Restrictions on the use of CCA preservativ...

Natural Durability Classification Systems Used Around the World
2009 - IRG/WP 09-10694
Around the world natural durability is classified in different ways. The nature and rigor of the tests used to measure durability, the method of classification based on these data, and use of these classifications to specify end uses or predict service life all vary. This can lead to confusion among people not familiar with the various systems used. This review describes the methods used to classi...

Correlation between different international standard assessment procedures with termites. Part 1: Field exposure
1983 - IRG/WP 1198
Ramin treated with copper-chrome-arsenic (CCA), pentachlorophenate and lindane, each at three retentions, and three other untreated timbers were assessed in the field against Coptotermes lacteus and Nasutitermes exitiosus. Replicate specimens were exposed around five mounds of each termite species over a period of five years in south-eastern Australia. The field results provided the basis for judg...
