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...

Towards harmonisation of regional approaches for an International Standard for the approval of wood preservatives
1997 - IRG/WP 97-20122
Recent proposals from the European Standards body (CEN) for an ISO Standard on wood preservatives has initiated debate on whether there is any prospect of an acceptable common approach among ISO member countries, to a harmonised framework of hazard classes, with agreed supporting biological tests, leading to a unified rationale for demonstrating compliance with minimum performance standards for sp...

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...

Further sets of data received from CTFT (France) after 18 months exposure, BAM (Germany) after 18 months exposure, STU (Sweden) after 9.5 months exposure and TI (Denmark) after 12 and 17.5 months exposure are presented and discussed in conjunction with data previously reported. The new data are generally in agreement with those presented previously and indicate the major difference between the co-...

International standards – which future?
2003 - IRG/WP 03-20277
A review of past and current activities at CEN/TC/38, within the scope of "wood durability, in relation with exposure" suggest that former activities linked to wood preservative efficacy shall formally include the balance safety/efficacy as a main part of the risk/benefit patterns. One way is an extensive development of liaisons. The case of OECD/CEN cooperation on emission assessment is a positiv...
