1972 - IRG/WP 211
Preservative: Tanalith CT.106 - Results obtained with beech are given in the table and indicate a toxic limit of 16.7-19.2 kg/m³ - The initial soil moisture content was adjusted to 27.8% (the water holding capacity). Noticeable drying out has occurred in some of the test bottles....

Collaborative soft rot tests
1981 - IRG/WP 2151
There appears to be need for reconsideration of attitudes towards Standardisation of laboratory tests for determining the toxicity of preservatives to soft rot fungi. The original approach was that a limited number of test methods were available and that collaborative effort would determine the suitability of the methods for Standardisation. It has been established so far that pure culture testing...

Collaborative experiments in testing the toxicity of wood preservatives to soft rot fungi
1970 - IRG/WP 25
Eight Institutes from seven countries, Austria, England, France, Germany, Holland, Sweden and Switzerland have collaborated in an attempt to assess the suitability of various laboratory test procedures for acceptance as standard methods of determining the toxicity of wood preservatives to the cellulose-attacking micro-fungi which cause 'soft rot' of wood. Pure culture methods wit...

Procedure for a collaborative study of leaching from CCA-treated timber in the sea
1988 - IRG/WP 4143
As a follow-up to the collaborative IRG/COIPM marine trial of CCA and CCB preservatives, a further trial is proposed with the objective of measuring the degree of leaching of CCA components from three timber species at marine sites in Malaysia and the U.K.. Details of the planned procedure are given....

A collaborative test to determine the efficacy of polyurethane coatings on wood samples exposed in the marine environment
1984 - IRG/WP 4113
Aims are: a) to determine the effectiveness of elastomeric polyurethane as a protective coating against marine wood boring animals in a range of tropical and tempreate sites; b) to compare the adhesion of polyurthane coatings on different wood species exposed in seawater; c) to record the severity of attack in failed samples and to identify the causal marine organisms....

Collaborative tests on the influence of solvent and drying method on the toxic limit of wood preservatives against Basidiomycetes
1974 - IRG/WP 248
Seven institutes from five countries, Austria, England, France, Germany and the Netherlands have collaborated in a study on the influences of solvent and drying method on the toxic limits of wood preservatives against Basidiomycetes tested according to the agar-block method. Two preservatives, a 25% pentachlorophenol-concentrate and tributyltinoxide were applied to pine sapwood and beech and teste...

Report on the status of collaborative experiments within the Sub-group on Basidiomycete tests
1983 - IRG/WP 2194
This report summarises the results of co-operative work carried out within the Sub-Group on Basidiomycete tests up to December 1982. The principle findings are recorded in the Conclusions Section. Work intended between IRG-13 in Turkey and IRG-14 in Australia is cited under Future Programme. An Annex provides a response sheet for existing and new participants to notify their contributions....

A collaborative test to determine the efficacy of poyurethane coatings on wood samples exposed in the marine environment. 1st Interim Report
1988 - IRG/WP 4145
Wood samples coated with elastomeric polyurethane (ca. 50 mils thick) were exposed for up to 2 years in 12 tropical and temperate marine test sites with known teredinid, pholad and/or crustacean infestations. All uncoated control samples were destroyed or partially destroyed. Polyurethane-coated samples were not attacked, the surfaces of the coating were sound and the polyurethane adhered well to ...

Collaborative soft rot tests: Paper for discussion in Working Group II
1970 - IRG/WP II 5A
An account of the major part of the collaborative work on laboratory tests of toxicity of preservatives to soft rot fungi initiated by the European Homologation Committee at Delft in 1966 has been published in ‘Material und Organismen’ (1970) as a report of progress. The main objective of these collaborative tests, namely to establish a reliable and acceptable standard test method was not acco...

Blue stain in timber in service. Results of further IRG collaborative tests to compare different artificial weathering systems
1981 - IRG/WP 2146
The previous work described in Document No IRG/WP/286 examined 3 preservatives (1% phenyl mercury succinate - PMS, 5% pentachlorophenol - PCP and 1.5% Preventol A4 - PA4) subjected to 5 different artificial weathering systems (BAM Xenotest, Cuprinol Marr, EMPA Xenotest, Gori Atlas and PRL Marr) and after natural weathering at 5 sites (BAM, Cuprinol, EMPA, Gori and PRL). Results showed good correla...

Collaborative soft rot tests: Tests conducted at Princes Risborough and Delft on soil samples from collaborating laboratories
1972 - IRG/WP 210
The laboratories which took part in the original collaborative soft rot test (Savory and Bravery, Holz u Org 5 (1) 58-90, 1970) sent samples of the soil used in the original test to Princes Risborough. Portions of this material were sent to Dr Hof for soil analyses at TNO and the remainder was employed at Princes Risborough for the conduct of comparative tests of soil virulence when used as a comb...

Collaborative soft rot tests: Statistical treatment of results of soil analyses
1971 - IRG/WP 29
Institutes taking part in the collaborative experiments already reported forwarded samples of the soils employed in the tests to the Forest Products Research Laboratory, England. The soils were then autoclaved sterilised under uniform conditions and sent to the Department of Forest Soils, the Royal College of Forestry, Stockholm, Sweden. The results of the soil analyses are given in Table 1, toget...

Collaborative soft rot tests: Final Report
1978 - IRG/WP 2106
Since preparation of Document No: IRG/WP/258 results have been received from the remaining collaborators. Thus there is a little further to add to the conclusions already derived, those in Document No: IRG/WP/251 being as follows: 1) the exposure system used sometimes resulted in excessive weight gains in the sterile check blocks. Consequently the corrected loss in weight of the test blocks could ...

Blue stain in timber in service. Preliminary results of the IRG collaborative tests to compare natural and artificial weathering
1978 - IRG/WP 286
The collaborative programme was initiated at IRG Meetings in Wildhaus, 1976. The six collaborators were BAM (Berlin), Cuprinol Ltd (UK), EMPA (Switzerland), GORI (Denmark), PRL (UK) and Imperial College (UK). Experimental plans were finalised in December 1976 and panels treated by Cuprinol Ltd early in 1977. Natural weathering was carried out by BAM, Cuprinol, EMPA, GORI and PRL during April-Septe...

Objectives of future collaborative soft rot tests
1972 - IRG/WP 209
Progress has been made towards acceptance of a defined laboratory test method for determining the toxicity of preservatives against soft rot fungi (Documents IRG/WP/201 and IRG/WP/208) and, at the 1971 meeting in Brussels, the framework of collaboration for the next phase of testing was discussed. Time available at Brussels did not permit restatement of objectives, consideration of the stages by w...

IRG/COIPM INTERNATIONAL MARINE TEST - To determine the effect of timber substrate on the efectiveness of different preservatives in sea-water: Coding scheme
1976 - IRG/WP 420
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 only the reference species treated with th...
