This European Standard specifies a marine test method fcar the determination of the relative effectlveness of a wood preservative applied by vacutBn/pressure iiipregnation or other prooesses 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 metiiod is applicable far testing any type of wood preservative, provided tiiat complete penetration of the test specimen is achieved.
NOTE : After suitable mcdification, it is possihle to assess the effectiveness of a preservative product in other wood species or its ef fectiveness when applied by methods other than vacuüm and pressure impregnation but only provided t±at a complete impregnation of the test specimens is achieved (1).
