The test specimens were treated at Akzo Nobel Industrial Coatings AB on with primer Aqua Combi WA D20 and topcoat Aqua Combi WA D20 under supervision of Elisabeth Morsing and Heidi Herup, Danish Technological Institute. The formulation is not disclosed. Method: EN 152-1: "Wood preservatives - Laboratory method for determining the protective effectiveness of a preservative treatment against blue stain in service. Part 1: Brushing procedure". Modification: Weathering was carried out by QUV according to cycle 1 in the revision of EN 152, CEN TC 38 WG 23 N 107 on 17 th March See the enclosed report no. 196/07 from Centre for Plastics Technology dated (Appendix 3). Result: Treatment Blue stain on surface (Average) Smallest depth of blue stain-free zone () * Mean depth of blue stain-free zone () * Tested system Reference without fungicide Untreated control, with Untreated control, without * Rounded off to Appendices: Note: Storage: Terms: Appendix 1. Surface treatment and. (1 page). Appendix 2. Detailed results of treatment and biological assessment. (3 pages). Appendix 3. Report from Centre for Plastics Technology. (2 pages). The interpretation of this test report and the practical conclusions that can be drawn from it require a basic knowledge of the problems of wood preservation. For this reason this test report alone does not indicate any official approval of the wood preservative tested. The samples will be destroyed after 6 months, if nothing else has been agreed in writing. The test has been performed according to the rear side conditions, which are according to the guidelines laid down by DANAK (The Danish Accreditation). The testing is only valid for the tested specimen.
