EN 14128:2020(Main)
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.

Durability of wood and wood-based products - Testing and classification of the durability to biological agents of wood and wood-based materials
SIST EN 350:2017

This European Standard gives guidance on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents.
The methods can be applied either to individual wood species, batches of wood and processed wood-based materials, including heat-treated, preservative-treated wood and modified wood. However, this standard is not intended to replace testing of the efficacy of biocides.
The wood-destroying agents considered in this standard are:
—   wood-decay fungi (basidiomycete and soft-rot fungi);
—   beetles capable of attacking dry wood;
—   termites;
—   marine organisms capable of attacking wood in service.
Data on the biological durability of selected wood species considered of economic importance in European countries are presented in Annex B (informative), which also provides information relating to their geographical origin, density, sapwood width and treatability.
NOTE   Treatability, durability to disfiguring fungi, permeability to water and performance in use of wood and wood-based materials are also important issues. However, because standardized methods aiming to assess and classify these factors do not exist and/or have not been extensively experienced yet, preliminary guidance is given in Annex C (informative) for the classification of wood treatability with aqueous wood preservatives, Annex D (informative) for the classification of the permeability to water, Annex E (informative) for the durability to disfiguring fungi, and Annex F (informative) for the classification of performance.

SIST-TP CEN/TR 15003:2013

This Technical Report specifies the minimum performance requirements for hot air treatment intended for application against specific classes of wood attacking organism. It specifies the minimum performance criteria to be achieved by hot air treatment.
NOTE   Until now sufficient practical experience and results of scientific tests are available only for heat treatments using hot air as a medium to increase the temperature inside building components up to a threshold lethal to wood destroying organisms. Therefore, this document is restricted to hot air treatments although other measures like, for example, radio waves or electric blankets may be useful means for limited and special applications.
This document is applicable only to hot air treatment, in so far as it is intended to cure attack by wood destroying beetles and the dry rot fungus (Serpula lacrymans).
This Technical Report is not applicable to eradicate an attack by termites or by fungi other than the dry rot fungus (Serpula lacrymans).
Hot air treatment as described in this document does not provide subsequent preventive protection against attack by wood-destroying organisms.
This document does not define the equipment, techniques or precise operation procedures required to achieve the parameters given in Clauses 4 and 5 for any set of practical circumstances. Specifications for particular practical circumstances have to be developed on a case by case basis by expert advisers/consultants.
