scope:

This European Standard describes a marine test method for determining the relative effectiveness of wood preservatives applied by vacuum/pressure impregnation or other processes giving deep penetration in order to prevent attack of timber in sea-water by marine wood boring organisms. The protective effect is assessed in relation to that of a reference preservative applied by a standard treatment. It is important to realize that the relationship between the results of these marine tests and performance in service may still vary for different preservatives. The method is suitable for testing any type of wood preservative, providing that complete penetration of the test specimen is achieved. After suitable modification, it is possible to assess the effectiveness of a preservative product in other wood species or its effectiveness when applied by methods other than vacuum and pressure impregnation but only provided that a complete impregnation of the test specimens is achieved.
