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...

Toxic values derived from EN 113 tests - are they determined by the virulence of a test fungus? - Results from a round robin test -
1999 - IRG/WP 99-20176
The virulence of Coniophora puteana BAM Ebw. 15, the obligatory test fungus on softwood in tests according to EN 113, is known to be rather inconstant at least in some laboratories. The mass losses of untreated Scots pine sapwood blocks in an EN 113 test may range from below 20% to up to more than 50%. Possible reasons for these differences as well as the impact of a low virulence on the toxic val...

A field study on the suitability of the European lap-joint test
2001 - IRG/WP 01-20239
Within the framework of the European SM&T Research Project "Co-normative research on field tests for wood preservatives out of ground contact in conjunction with methods for preconditioning test specimens prior to test" (FACT) one aim was to establish the suitability of the European lap-joint test (as it is described in ENV 12037:1996) to assess wood preservatives in the field in EHC 3. Scots ...
