This Technical Report presents a summary of the research of the S.M.T. Project: F.A.C.T, SMT4 CT96 2135. Assuch it details the supporting information for the proposals for a new conditioning standard to replace EN 73 andEN 84 and for modification and validation of ENV 12037. The full report is presented and referenced to Technicalannexes, which are available on request.The FACT project involved the study of the fate of chosen wood preservatives in field and laboratory tests and theaffect on biological performance. The work consisted of four core tasks and associated sub-tasks designed toprovide the scientific background to the proposals made.Task 1This consisted of a study of artificial weathering techniques for the conditioning of treated test blocks prior tobiological test. It was originally hoped that it might be possible to relate different weathering cycles to the differentclimatic conditions found within Europe. However this did not prove possible but it is possible to recommend asingle weathering cycle to replace the use of EN 73 and EN 84. A draft experimental standard has been preparedbased on the findings of this work.All the supporting data and associated studies are summarised in this Technical report in clauses 5 and 6.Task 2This task consisted of an extensive field test based on ENV 12037 and associated sub-tasks. The method provedvery robust but significant modifications are recommended and the ENV is to be redrafted in the light of resultscontained in this report. This field test should be considered as ‘simulated service trial’ rather than an acceleratedfield test; a concept that needs careful consideration within the EN 599 framework.Sub-tasks 2.3 and 2.4 examined the suitability of the method for composites and the testing of naturally durabletimbers. At this stage it is too early to make recommendation for their inclusion in the standard but the results lookpromising and the method will probably be modified at a later revision.Tasks 3 and 4These tasks examined the role of bio-conditioning of test samples in ‘use class’ 3 and 4. The results are presentedin clauses 8 and 9 and clearly indicate the importance of this subject. It is recommended that urgent attention isgiven to taking this work further particularly for the testing of organic based preservatives. Although not yet readyfor standardisation, the results presented here will prove invaluable to industry in designing developmentprogrammes for the new generation of organic based preservatives.In summary:a new experimental standard will be produced to replace EN 73 and EN 84 for the physical conditioning of testblocks;ENV 12037 will be modified to take into account the extensive findings of the project;the use of ENV 12037 for natural durability and composite testing will be considered when more results areavailable;further work on biological conditions is urgently recommended.
