Proposed method for out-of-ground contact trials of exterior joinery protection systems
1981 - IRG/WP 2157
Methods for testing the efficacy of preservative treatments for exterior joinery are described using the format of a European Standard. Commercially used treatments applied to jointed test units (L-joints) which are then protected by conventional finishes are exposed to normal outdoor hazards out of ground contact. Assessment is made a) by determining eventual failure through decay and b) by destr...

1973 - IRG/WP 223
These tests were undertaken as a preliminary to the next series of collaborative soft rot tests. An interim report has already been presented at Berlin in 1972 as Document No: IRG/WP/211...

Soil virulence tests using Scots pine sapwood
1973 - IRG/WP 222
Following the tests reported in Document No: IRG/WP/210, in which soils from different laboratories were investigated for virulence, supplementary tests have been carried out using Scots pine sapwood and an extended incubation period....

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...

Collaborative soft rot tests: Interim report on PRL tests of Cu/Cr/As preservative using method of Document No: IRG/WP/208
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....

An approach to testing the preventive effectiveness of preservative treatments for wooden joinery
1981 - IRG/WP 2156
The ecological sequence established in field trial samples exposed out of ground contact has shown the need for outdoor exposure in testing potential joinery preservative pretreatments. A system of exposure of L-joint units is proposed. Data obtained by examining samples destructively show promise as the basis for predicting service life after relatively short exposure periods (within 2 years)....

Collaborative soft rot test: Amended test method
1972 - IRG/WP 208
The initial draft of a standard test method (Document IRG/WP/201) was discussed at the meeting in Brussels in 1971. It was agreed that a revised draft should be prepared and that the Princes Risborough Laboratory (formerly FPRL) should conduct a trial test using the method as a preliminary to the main collaborative test....

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 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...

Addendum to paper for discussion in Working II
1970 - IRG/WP II 5B
In view of the limited time that will be available for discussions in Nancy, this addendum has been prepared. Arising from the previous collaborative work and Mr Bravery’s visit to most of the co-operating Institutes, a scheme of work entailing tests carried out 1) by a technique chosen by individual Institutes; 2) by an agreed standardised technique would appear to be the best approach. A compl...

Research on wood protection at the Princes Risborough Laboratory 1975 & 1976
1977 - IRG/WP 3109
This paper is the latest of a 2-yearly series presenting a summarised account of the Laboratory's work in wood preservatives and related fields. The topics dealt with include: environmental studies on the usage of copper-chrome-arsenic and organic solvent preservatives; development of National and International Standards; recent developments in the preservation of external doors and windo...

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: 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 ...

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...

Factors affecting the resistance of fibre building boards to fungal attack
1975 - IRG/WP 252
Fungal decay is initiated at lower moisture contents in standard and tempered hardboards (18%) than in pine sapwood (26%). In contrast, in a saturated atmosphere, the equilibrium moisture contents of standard hardboard (14%) and of tempered hardboard (12.5%) are much lower than the moisture content permitting decay initiation whilst the equilibrium moisture content of pine sapwood (25.1%) approach...
