| Popis: | This work evaluates different experimental heated oil treatments that are being developed for wooden items used above ground (Hazard Class III). Threshold limit values in accordance with European Standard EN 113 (1996) were established for these treatments. The biocidal heated oil treatment examined is based on a vegetablemineral oil mixture combined with two triazole fungicides, propiconazole and tebuconazole; it is not a traditional wood preservative, as its efficacy is based on a dual effect, water repellence due to oil and chemical protection due to fungicides. The high level of water repellency caused some test blocks to remain too dry for decay to occur, so the validity requirements of the EN 113 standard test were not met. There are clearly limitations in conducting EN 113 tests when highly water repellent treatments are to be evaluated. Where conclusions could be drawn, the results indicate that the triazoles did not perform as well in the heated oil system as would have been anticipated. It is concluded that to gain a true indication of how biocidal heated oil treatments will perform in service, field trials need to be undertaken. |
