A further European Standard (at present still in preparation) is concerned with criteria for hot air processes forcurative uses against wood destroying organisms.This European Standard is valid for products to eradicate beetles in infested wood and for products to be used inthe course of curative actions against the dry rot fungus to prevent its growth through masonry and beyond.The annexes B and C are normative.The annexes A, D, E and F are informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 14128:2004
EN 14128:2003 (E)4IntroductionThis European Standard should be used in conjunction with prEN WI 00038084 (at present still in preparation) andwith EN 599-1 which describes the performance requirements for preventive wood preservatives as determined bybiological tests.The need to use curative products against wood destroying organisms depends upon a careful diagnosis by expert,qualified specialists to determine the precise causes of the damage to be rectified. This should include the type ofwood attacking organisms involved and whether they are active, the environmental circumstances, especially thesource and nature of any wetting, the type of wood involved, the nature of the building or construction, and thestructural and physical significance of the timber which is damaged or at risk of being damaged.Curative treatment can be achieved either by chemical wood preservatives as specified in this European Standardor by specific curative processes without using chemicals, like hot air processes, as given in prEN WI 00038084.Curative wood preservative products should be used in an integrated way as part of a carefully prescribed strategyinvolving a series of actions appropriate to the particular circumstances of each case. Associated physicalmeasures involving appropriate building works to remedy ingress of moisture and to dry out any dampness can bean essential prerequisite for the use of any curative products. Expert diagnosis should take into account allregional, practical, environmental, economical, safety and any other factors which can be relevant to theprescriptive decisions to be taken.It is not the purpose of this European Standard to provide a specification, or even guidance in developingspecifications for remedial work to eradicate wood destroying organisms. This European Standard also does notgive guidance on the methods of application or the precise amounts of products that might be appropriate to applyin specific practical circumstances. It is intended to guide specifiers, users and others in selecting and specifyingproducts on the basis of their effectiveness as demonstrated in accordance with the criteria given.SIST EN 14128:2004
EN 14128:2003 (E)51 ScopeThis European Standard specifies the minimum performance requirements in biological tests for products forcurative uses against specific wood destroying organisms. It specifies the biological tests required together with theperformance 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 aftera long period (slow acting or with a deferred effect). Different tests and performance requirements are needed forthese various types of curative wood preservatives.This European Standard is applicable to all wood preservative products supplied for application in liquid form forcurative uses against attack by wood attacking insects, excluding termites. This European Standard is alsoapplicable 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 orin capsule form but only where appropriate biological methods of test exist as published European Standards or asnormative annexes to this European Standard.NOTE 1The nature of the laboratory tests required in this European Standard is such that the time required to generate datais many months sometimes more than one year, depending upon the type of product and the organism(s) it is intended to beused against.Therefore, at the date of publication of this European Standard, for many products covered under its scope already placed onthe market and used lawfully in accordance with local technical traditions, the minimum data specified in this standard may notbe available. Accordingly, for a period not exceeding 3 years from the date of publication of this European Standard, nationalstandards organisations, or an organisation nominated by them may declare interim effective values for use within theirterritories, to apply to products already placed on the market and used lawfully in accordance with local traditions at the date ofuse of this European Standard.NOTE 2For re-testing after making variations in product formulation, guidance is given in annex A.This European Standard is not applicable to products used as fumigants.This European Standard is also not applicable for determining whether specific curative products, used alone or incombination, are effective in conferring long-term preventive action against attack by wood destroying organisms inthe future. Preventive effectiveness can be determined using EN 599-1 but only for products whose nature allowthem to be tested using the methods and interpretative procedures defined in EN 599-1. Amendments of existingtest methods cited in EN 599-1 may be used but only when defined in normative annexes to this EuropeanStandard.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

Thefungus can develop at relatively low wood moisture contents and is able to penetrate damp masonry over longdistances in order to infect further timber or to develop its fruit-bodies.SIST EN 14128:2004
EN 14128:2003 (E)85 Performance requirements for products against beetles (see Table 1)5.1 Principle requirements for curative efficacyThe curative wood preservative product shall be tested in accordance with the tests specified in Table 1, taking intoconsideration the relevant organisms and the type of insecticidal product (see 5.2.2).5.2 Supplementary requirements for curative efficacy5.2.1For Lyctus brunneus, Xestobium rufovillosum and Hesperophanes cinnereus no specific requirements arelisted, as no relevant/valid test standards exist.NOTEIn the case of Lyctus brunneus, curative treatment takes place only exceptionally so that specific preservatives areplaced only very rarely on the market. Due to economical reasons, no specific test procedure will be established. If curativetreatment against Lyctus brunneus is demanded, a curative wood preservative "for Hylotrupes and Anobium" should be applied.In the case of Xestobium rufovillosum see annex B.In the case of Hesperophanes cinnereus see annex C.5.2.2The following types of insecticidal products have to be considered:¾ fast acting products;¾ slow acting products;¾ products with deferred effect.5.2.3Tests of insecticidal activity shall be carried out against one of the following:a) "Hylotrupes bajulus (C-H)" and "Anobium punctatum (C-A)" unless b) or c) is applicable and is selected;orb) the more tolerant beetle species, if the product is based on insecticide(s) for which data on curative efficacyalready exist which show different activities against Hylotrupes bajulus and Anobium punctatum, that is theeffective value for the less tolerant species is less than 80 % of the effective amount for the more tolerantspecies;orc) against "Hylotrupes bajulus (C-H)" or "Anobium punctatum (C-A)", if the product is based on insecticide(s) forwhich data on the curative efficacy already exist which show more or less equal activity against both beetlespecies, that is the effective value of the least tolerant beetle species is equal to or greater than 80 % of theeffective value of the more tolerant beetle species.5.2.4New tests shall be carried out against Hylotrupes bajulus according to ENV 1390, however, former resultsfrom EN 22 tests shall remain valid.5.2.5At present no relevant test standards exist for deferred effect products.5.2.6The maximum application limit shall not exceed 300 ml per square meter.NOTE 1If the curative wood preservative is specified by the manufacturer to be used at a higher application in practice, themanufacturer should define how this amount is to be achieved under practical conditions.NOTE 2If the curative wood preservative is already placed on the market on the basis of results from biological testsconducted at a maximum application limit greater than 300 ml per square meter, these test results remain valid and no newtests should be demanded.SIST EN 14128:2004
EN 14128:2003 (E)95.2.7For tests according to EN 370 the duration can exceed 1 year.5.2.8If the curative wood preservative is designed to be used for the protection of items of cultural heritage forAnobium punctatum the mortality at the end of the test shall be 90 %.5.3 Requirements for preventive efficacyWhere local conditions require the curative wood preservative product to have also preventive efficacy, or tosupport the claims of manufacturers or the demands of specifiers, the product shall have its preventive efficacydemonstrated from tests in accordance with EN 599-1 at an application limit equal to or lower than that at whichtest under this curative standard were conducted.6 Performance requirements for barrier treatments against dry rot fungusIn tests according to ENV 12404 growth through mortar specimens and infection of the wood specimens shall havebeen prevented by the masonry fungicide. The application rate of the ready to use solution of the fungicide shall benot lower than 500 ml per square meter and not more than 750 ml per square meter.7 Derivation of effective values7.1 Effective value against beetlesThe effective value is derived from the results of the biological tests and shall be equal to the application rate of thewood preservative tested according to the manufacturer's recommendation (see 5.2.6).7.2 Effective value against dry rot fungusThe effective value is derived from the
