This European Standard specifies a marine test method for the determination of the relative effectiveness of a wood preservative applied by vacuum/pressure impregnation or other processes which would lead to deep penetration of the test specimens 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 can still vary for different preservatives.
This method is applicable for testing any type of wood preservative, provided that complete penetration of the test specimen is achieved.
NOTE. 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.
note:1)The only specific European aspect of this standard lies in the choice of the obligatory reference species Pinus sylvestris. The method can be used with any other timber species of preference and is not specific to Europe in its field of application.
