Underground timber constructions from the First World War are well preserved after 100 years
2017 - IRG/WP 17-10897
During the Great War or World War I many underground constructions have been built for protection from shelling. They were an important part of the trench warfare as they were used as an area to rest and carry out other activities such as eating. They would usually range in size from smaller constructions that could hold several men to larger entities that could hold thousands of soldiers. In the ...

Coding scheme for samples for IRG world-wide co-operative field experiment
1975 - IRG/WP 360
Each sample has been given a number containing six digits (eg 16 23 05). The first 2 digits indicate the country and person supplying the timber, the second 2 digits indicate the species of timber, and the last two digits indicate the treating concentration. All samples which end with the numbers 26 to 50 are to be placed in one site in the United Kingdom, probably at the Imperial College site at ...

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...

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...

World survey on the status of pollution control in the field of wood preservation
1976 - IRG/WP 369
In 1974 the IRG/WP-Secretariat distributed a "Questionnaire on the state of pollution control in the field of wood preservation" which was prepared by the author. The questionnaire consisted of two parts. Part A asked "General questions" on - the position of wood preservation in the respective country - the use of preservatives - the type of application of wood preservatives in different fields - ...
Interim report on world survey of sap displacement impregnation of timber
1974 - IRG/WP 329
At the 4th Annual Meeting of the IRG held in West Berlin in October 1972 it was suggested that a survey of sap displacement impregnation of timber would be of interest. Accordingly through the courtesy and co-operation of the New Zealand Department of Trade and Industry a questionnaire was circulated to the Trade Commissioners for transmission to the relevant organisations in various parts of the ...

Hardwood field experiment: Progress report 1977-82
1982 - IRG/WP 3200
The international hardwood field experiment was planned in 1976 and set up in some 30 different sites around the world. The test stakes include 4 reference species common to each site and in most cases at least 2 species of local importance. It was hoped that a picture of performance of a range of economically important species would be built up and at the same time provide vital background inform...

World list of wood preservative names
1980 - IRG/WP 387
The list contains names that have been collected by the author over many years and includes besides traditional wood preservatives, exterior wood finishes and preservative stains, and some preservative coatings. Generally, however, primers and paints have been deliberately excluded. The list includes also products that have been claimed as wood preservatives, as well as a few fire-retardant coatin...
Preliminary results from the field experiment to determine the performance of preservative treated hardwoods with particular reference to soft rot. The four reference timber
1980 - IRG/WP 3164
The results given in the Tables 1-4 each refer to one of the four reference species treated with four solution concentrations of CCA as recorded from each test site. The species are: Alstonia scholaris, Betula pendula, Fagus sylvatica, Pinus sylvestris. The treatments were: Untreated, 0.66% CCA, 1.53% CCA, 3.01% CCA, 5.60% CCA. Each figure is an average of the ratings recorded for each replicate o...

Current state of world standardization in the toxicometric methods for testing of wood preservatives
2007 - IRG/WP 07-20354
The paper presents an outline of the history of forming standardized toxicometric methods for testing of wood preservatives in the world during last 100 years. Numerous studies resulted in three main methods which are currently used for official and basis assessment of biocides: - agar-block method in Europe (EN 113); - soil-block method in the USA and Pacific countries (ASTM D 1413); - modifi...
Drywood termites in the Azores: Problems and tentative solutions
2009 - IRG/WP 09-10698
The detection in 2002 of drywood termites in the islands of Azores has became an urgent issue to be coped with given the fast degradation that structural elements can show after a short period of installation of a colony. A recent study indicates drywood termite presence in about half of the buildings of the historic centre of Angra do Heroísmo (a World Heritage site) in Terceira Island and timbe...

Cryptotermes brevis - a silent earthquake for the wood structures in a World Heritage city in the Azores Islands
2016 - IRG/WP 16-50316
In the Azores archipelago the exotic drywood termite Cryptotermes brevis, detected in early 2000’s, is destroying the wood structures of the typical buildings and is already considered the main urban pest in these islands. This work aims to show the spread evolution of this pest along the last six years in the first Portuguese city classified as world heritage by UNESCO, Angra do Heroísmo. For ...
