What is BS EN 599-2 - Efficacy of preventive wood preservatives about ?
BS EN 599-2 is the second part of the multi-series standard that 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.
BS EN 599-2 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 effect of the product.
Note: BS EN 599-2 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 from causing sap stain on green (unseasoned) timber.

Why should you use BS EN 599-2 - Efficacy of preventive wood preservatives ?
BS EN 599-2 is used in conjunction with EN 599-1, with EN 335, which describes the use classes of treated wood, and with EN 351-1, which describes a classification system for preservative-treated wood in terms of preservative penetration and gives guidance on retention requirements. The need for wood preservatives depends in part on the natural durability of the wood and therefore this part of EN 599 should be used also in conjunction with EN 350 and EN 460.
BS EN 599-2 will help you how to report efficacy information on a label relating to wood preservative efficacy.
