Structural timber - Structural timber preservative treated against biological attack

Structural timber - Structural timber preservative treated against biological attack

This European Standard specifies general requirements for structural timber that has been treated with preservatives against biological attack.
This European Standard also specifies requirements for the evaluation of conformity and marking of preservative treated timber products when they are placed on the market.
Treatments, which include a biocide, are covered by this standard.
It does not provide details of which preservative treatments are necessary for a particular type of structural timber product to achieve a required service life, as regional climatic differences and prevalent biological agents would need to be taken into account for that purpose.
This European Standard does not cover any subsequent treatment which may be required for structural timber products which have been machined, bored or planed after the CE marking has been applied.
This standard does not cover the qualification of preservation products used to treat structural timber.

Durability of wood and wood-based products - Efficacy criteria for curative wood preservatives as determined by biological tests
SIST EN 14128:2020

This document 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 efficacy 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 efficacy requirements are needed for these various types of curative wood preservatives.
This document is applicable to all wood preservative products supplied for application in liquid form for curative uses against attack by wood boring beetles. This document is also applicable for products applied to prevent the growth of the dry rot fungus through masonry.
This document 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.
NOTE   This standard is used as a reference document for the evaluation of efficacy of biocidal products PT8 (wood preservatives) in the framework of the European Regulation on Biocidal Products (EU) No 528/2012 (BPR).
This document is not applicable to products used as fumigants.
This document is also not applicable for determining whether specific curative products, used alone or in combination, are effective in conferring long-term protection against attack by wood destroying organisms. Preventive effectiveness can be determined using EN 599-1 but only for products that can be tested using the methods and interpretative procedures defined in EN 599-1.
Annex A (informative) contains a guidance on re-testing after making variations in product formulation.
Annex B (informative) contains some test recommendations for specific curative products against other insect species than Hylotrupes bajulus and Anobium punctatum.

Durability of wood and wood-based products - Efficacy of preventive wood preservatives as determined by biological tests - Part 2: Labelling
SIST EN 599-2:2017

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.
