Durability of wood and wood-based products - Performance criteria for curative wood preservatives as determined by biological tests
This European Standard specifies the minimum performance requirements in biological tests for products for curative uses against specific wood destroying organisms. It specifies the biological tests required together with the performance criteria to be achieved in each test.
Chemicals against insects can act according to their specific properties within a short time (fast acting) or only after a long period (slow acting or with a deferred effect). Different tests and performance requirements are needed for these various types of curative wood preservatives.
This European Standard is applicable to all wood preservative products supplied for application in liquid form for curative uses against attack by wood attacking insects, excluding termites. This European Standard is also applicable for products applied to prevent growth of dry rot fungus through masonry.
This European Standard is also applicable to products for curative uses supplied for application as pastes, solids or in capsule form but only where appropriate biological methods of test exist as published European Standards or as normative annexes to this European Standard.
NOTE 1 The nature of the laboratory tests required in this European Standard is such that the time required to generate data is many months sometimes more than one year, depending upon the type of product and the organism(s) it is intended to be used against. Therefore, at the date of publication of this European Standard, for many products covered under its scope already placed on the market and used lawfully in accordance with local technical traditions, the minimum data specified in this standard may not be available.
