Although Austria is a small country, the annual consumption of anti-sapstain products ranks to approximately 500 tons annually. In 1994, only three products will be approved by the Austrian Wood Preservation Committee (AWPEC). There is demand for a field test method, which demonstrates the efficacy of an anti-sapstain product and consequently implies the acceptance and approval of product by the AWPEC. Present field test was carried out in 1992 and 1993. The results were evaluated after six months storage of test stacks. A TCMTB based product was used as a reference. The results show that the AFPRL method proves very suitable for the simulation of practical situation in Austrian treatment plants, where pine and/or spruce are treated periodically and where different methods of stack storage are applied.
