Glulaminated poles - Progress report after 7 years' testing
1987 - IRG/WP 3444
In 1979 a number of glulaminated poles with various preservative treatments were placed in a greenhouse at Uppsala, at the Simlångsdalen test field in southern Sweden and under a power line just south of the Arctic circle in order to study their resistance against biological degradation. The tests have shown that the comparatively best performance will be obtained if each lamination is treated wi...

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 1: Treatment of reference samples
1977 - IRG/WP 426
It was agreed in Wildhaus on 15 May 1976 that preparations for the test detailed in Document No: IRG/WP/414 should commence immediately, but that initially only two water-borne preservatives should be used - a copper/chrome/arsenic (CCA) and a copper/chrome/boron (CCB) formulation respectively. PRL, England (R Cockcroft) would be responsible for supplying samples of the reference timbers treated w...

Interim report on the use of borate rods for the in-situ treatment of joinery
1980 - IRG/WP 3159
In the U.K. in recent years, it has been recognised that there is a major need for in-situ treatment of joinery at risk from or showing the early signs of decay. Several techniques have been developed to provide such a treatment, one of which is based on the insertion of anhydrous borate glass rods. The tests in hand are long term and this report is confined to the mycological isolation data from ...

Hardwood field experiment - 10 year report
1989 - IRG/WP 3560
The international hardwood field experiment was planned in 1976 and set up in some 34 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 (supplementary species). It was hoped that a picture of performance of a range of economically important timber species would be built up and at the same time ...

Marine trial progress report
1980 - IRG/WP 453
In May 1977 and May 1978, tests of new chemical formulations for the protection of timber in the sea were installed in Mt. Maunganui Harbour. Investigation into new preservatives for such usage was urgently required since it had been found that there was progressive leaching of copper from copper-chrome-arsenate treated marine piles which could lead to a reduction in their service life. Hochmann (...

Report on the co-operative leaching tests
1975 - IRG/WP 246
The Work reported here was undertaken at the request of CEN to see (1) whether the standard beaker leaching method under discussion at CEN, and based on the German DIN could be made less labour intensive; and (2) whether the leaching parameters could be expressed in more general terms so that alternative procedures could be used. A co-operative experiment was set up in which the amount of leaching...

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 21: Report of eighth inspection (7 years) in Australia
1985 - IRG/WP 4119
This report tabulates the seven year (86 month) inspection results, obtained on 28 Fabruary l985, of the IRG/COIPM International Marine Test at Goat Island, Australia. This test was installed in December 1977. The results are given in Tables 1-6. Table 7 lists the number of marine borers identified from blocks (2 cm and 6 cm long respectively) cut from the ends of specimens removed at the previous...

Information regarding a report on the "Code of Good Practice" for the use of chlorophenoxides for wood preservation
1984 - IRG/WP 3302
In 1981 the British Columbia Chlorophenate Wood Protection Task Force was formed to respond to workers' health and environmental concerns regarding the use of chlorophenoxides for control of sapstain and mould fungi at sawmills and lumber export terminals. The task force consisted of representatives of both the federal government (Environment Canada) and the provincial government (British...

Remedial ground-line treatment of CCA poles in service. A final report after 60 months' testing
1989 - IRG/WP 3534
Remedial treatment of CCA treated utility poles of Pinus sylvestris with incipient decay was carried out in 1983 and the results of chemical and microbiological analyses 6 months after treatment were reported in Document No: IRG/WP/3388 while microbiological studies 12 and 28 months after treatment as well as chemical analyses of poles treated with boron rods or boric acid paste 28 months after tr...

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 ...

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...
