BS EN 599-2:2016

This standard BS EN 599-2:2016 Durability of wood and wood-based products. Efficacy of preventive wood preservatives as determined by biological tests is classified in these ICS categories:

• 71.100.50 Wood-protecting chemicals

This European Standard specifies the requirements for labelling wood preservative products according to their efficacy and suitability for use, for each of the five use classes defined in EN 335 .

This European Standard is applicable to all wood preservative products supplied for application in liquid form for the preventive treatment of timbers (structural and non-structural) against wood-attacking fungi, wood-attacking insects and marine organisms as described in EN 1001‑2 and EN 335 . It is applicable to products for preventive treatments against fungi causing disfigurement (blue stain) of wood in service, only if this forms part of the overall preventive effectiveness of the product.

This European Standard is not applicable to wood preservative products supplied for application as pastes, solids or in capsule form because they cannot be tested without modification of the biological tests demanded in this standard. It does not apply either to wood preservative products for remedial (curative) treatments or to those applied to prevent fungi causing sap stain on green (unseasoned) timber.
