Durability of wood and wood-based products - Efficacy criteria for curative wood preservatives as determined by biological tests

This European Standard 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 European Standard is applicable to all wood preservative products supplied for application in liquid form for curative uses against attack by wood boring beetles. This European Standard is also applicable for products applied to prevent the growth of the dry rot fungus through masonry.
This European Standard 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 or as normative annexes to this European Standard.
NOTE 1   For re-testing after making variations in product formulation, guidance is given in Annex A.
NOTE 2   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 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 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.
Annex C (informative) contains a guidance for physical chemical properties.

Dauerhaftigkeit von Holz und Holzprodukten - Anforderungen an bekämpfend wirkende Holzschutzmittel, wie sie durch biologische Prüfungen ermittelt werden

Diese Europäische Norm legt die Mindestleistungsanforderungen in biologischen Prüfungen für Produkte zur bekämpfenden Behandlung gegen bestimmte Holz zerstörende Organismen fest. Sie legt die geforderten biologischen Prüfungen in Verbindung mit den Wirksamkeitskriterien fest, die in jeder Prüfung erfüllt werden müssen.
Chemikalien gegen Insekten können entsprechend ihren spezifischen Eigenschaften innerhalb einer kurzen Zeit (schnell wirkend) oder erst nach langer Zeit wirken (langsam wirkend oder mit verzögertem Effekt). Für diese verschiedenen Typen von Bekämpfungsmitteln werden unterschiedliche Prüfungen und Wirksamkeitsanforderungen benötigt.
Diese Europäische Norm gilt für alle Holzschutzmittel, die zur Anwendung in flüssiger Form für Bekämpfungsmaßnahmen gegen Holz zerstörende Käfer geliefert werden. Diese Europäische Norm gilt auch für Produkte zur Verhinderung des Durchwachsens von Echtem Hausschwamm durch Mauerwerk.
Diese Europäische Norm gilt auch für Produkte, die für Bekämpfungsmaßnahmen als Pasten, Presslinge oder in verkapselter Form angeboten werden, aber nur, soweit geeignete biologische Prüfverfahren als veröffentlichte Europäische Normen oder als normative Anhänge zu dieser Europäischen Norm vorliegen.
ANMERKUNG 1   Leitlinien für die Wiederholung von Prüfungen nach Veränderungen in der Formulierung des Produkts sind in Anhang A enthalten.
ANMERKUNG 2   Diese Norm dient als Referenzdokument zur Bewertung der Wirksamkeit von Biozidprodukten PT8 (Holzschutzmittel) im Rahmen der Europäischen Verordnung (EU) Nr. 528/2012 zu Biozid-produkten (BPR).
Diese Europäische Norm gilt nicht für Produkte, die als Gase eingesetzt werden.
Diese Europäische Norm gilt ebenfalls nicht zur Bestimmung, ob spezielle Bekämpfungsmittel, die allein oder im Verbund angewendet werden, geeignet sind, einen Langzeitschutz gegen einen Befall durch Holz zerstörende Organismen zu bewirken. Eine vorbeugende Wirksamkeit kann unter Anwendung von EN 599 1 bestimmt werden, jedoch nur für Produkte, die unter Anwendung der Methoden und interpretierten Verfahren nach EN 599 1 geprüft werden können.
Anhang A (informativ) enthält Leitlinien für die Wiederholung von Prüfungen nach Veränderungen in der Formulierung des Produkts.
Anhang B (informativ) enthält einige Prüfempfehlungen für spezielle Produkte zur bekämpfenden Behandlung gegen andere Insektenarten als Hylotrupes bajulus und Anobium punctatum.
Anhang C (informativ) enthält Leitlinien für physikalisch-chemische Eigenschaften.

Durabilité du bois et des matériaux dérivés du bois - Efficacité des produits curatifs de préservation du bois établis par des essais biologiques

La présente Norme européenne spécifie les exigences minimales de performance dans des essais biologiques des produits curatifs contre des organismes spécifiques attaquant le bois. Elle précise les essais biologiques requis avec les critères d'efficacité à atteindre pour chaque essai.
Les produits chimiques insecticides peuvent, suivant leurs propriétés spécifiques, agir dans un temps court (action rapide) ou seulement après une longue période (action lente ou à effet différé). Des essais et des exigences d'efficacité différents sont nécessaires pour ces divers types de produits curatifs de préservation du bois.
Cette Norme européenne s'applique à toutes les formulations de produit de préservation du bois destinées à être mises en oeuvre sous forme liquide pour le traitement curatif des bois vis-à-vis des coléoptères xylophages. Cette Norme européenne s'applique également aux produits utilisés pour empêcher le développement de la mérule au travers de la maçonnerie.
Cette Norme européenne s'applique aussi aux produits curatifs mis en oeuvre sous forme de pâte, sous forme solide ou encapsulés, mais seulement si des méthodes d'essais biologiques appropriées existent en tant que normes européennes publiées ou en tant qu'annexes normatives à la présente Norme européenne.
NOTE 1   Pour refaire des essais après des modifications de formulation, des recommandations sont données dans l'Annexe A.
NOTE 2   La présente norme est utilisée comme document de référence pour l'évaluation de l'efficacité des produits biocides PT8 (produits de préservation du bois) dans le cadre du règlement européen (UE) No 528/2012 sur l'utilisation des produits biocides.
La présente Norme européenne n'est pas applicable aux produits utilisés en fumigation.
La présente Norme européenne n'est également pas applicable pour déterminer si des produits curatifs spécifiques, utilisés seuls ou en combinaison, confèrent une protection à long terme contre les organismes lignivores. L'efficacité préventive peut être déterminée à l'aide de l'EN 599-1 mais seulement pour les produits qui peuvent être testés en utilisant les méthodes et les règles d'interprétation définies dans l'EN 599-1.
L'Annexe A (informative) contient des recommandations relatives aux essais à refaire suite à des modifications apportées à la formulation du produit.
L'Annexe B (informative) contient des recommandations d'essai pour des produits curatifs spécifiques contre d'autres espèces d'insectes que Hylotrupes bajulus et Anobium punctatum.
L'Annexe C (informative) contient des recommandations relatives aux propriétés physico-chimiques.

Introduction
This document should be used in conjunction with EN 599-1, which describes the performance
requirements for preventive wood preservatives as determined by biological 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 of wood attacking organisms involved and whether they are active, the environmental
circumstances, especially the source and nature of any wetting, the type of wood involved, the nature of
the building or construction, and the structural and physical significance of the timber which is damaged
or at risk of being damaged.
NOTE Curative treatment can be achieved either by chemical wood preservatives as specified in this document
or by specific curative processes without using chemicals, like hot air processes, as given in CEN/TR 15003.
Curative wood preservative products should be used in an integrated way as part of a carefully prescribed
strategy involving a series of actions appropriate to the particular circumstances of each case. Associated
physical measures involving appropriate building works to remedy ingress of moisture and to dry out
any dampness can be an essential prerequisite for the use of any curative products. Expert diagnosis
should take into account all regional, practical, environmental, economical, safety and any other factors
which can be relevant to the prescriptive decisions to be taken.
It is not the purpose of this document to provide a specification, or even guidance in developing
specifications for remedial work to eradicate wood destroying organisms. This document also does not
give guidance on the methods of application or the precise amounts of products that might be appropriate
to apply in specific practical circumstances. It is intended to guide specifiers, users and others in selecting
and specifying products on the basis of their effectiveness as demonstrated in accordance with the
criteria given.

Introduction
This document should be used in conjunction with EN 599-1, which describes the performance
requirements for preventive wood preservatives as determined by biological 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 of wood attacking organisms involved and whether they are active, the environmental
circumstances, especially the source and nature of any wetting, the type of wood involved, the nature of
the building or construction, and the structural and physical significance of the timber which is damaged
or at risk of being damaged.
NOTE Curative treatment can be achieved either by chemical wood preservatives as specified in this document
or by specific curative processes without using chemicals, like hot air processes, as given in CEN/TR 15003.
Curative wood preservative products should be used in an integrated way as part of a carefully prescribed
strategy involving a series of actions appropriate to the particular circumstances of each case. Associated
physical measures involving appropriate building works to remedy ingress of moisture and to dry out
any dampness can be an essential prerequisite for the use of any curative products. Expert diagnosis
should take into account all regional, practical, environmental, economical, safety and any other factors
which can be relevant to the prescriptive decisions to be taken.
It is not the purpose of this document to provide a specification, or even guidance in developing
specifications for remedial work to eradicate wood destroying organisms. This document also does not
give guidance on the methods of application or the precise amounts of products that might be appropriate
to apply in specific practical circumstances. It is intended to guide specifiers, users and others in selecting
and specifying products on the basis of their effectiveness as demonstrated in accordance with the
criteria given.

1 Scope
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.

Introduction
This European Standard should be used in conjunction with EN 599-1, which describes the performance
requirements for preventive wood preservatives as determined by biological 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 of wood attacking organisms involved and whether they are active, the environmental
circumstances, especially the source and nature of any wetting, the type of wood involved, the nature of
the building or construction, and the structural 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
Standard or by specific curative processes without using chemicals, like hot air processes, as given in
CEN/TR 15003.
Curative wood preservative products should be used in an integrated way as part of a carefully prescribed
strategy involving a series of actions appropriate to the particular circumstances of each case. Associated
physical measures involving appropriate building works to remedy ingress of moisture and to dry out
any dampness can be an essential prerequisite for the use of any curative products. Expert diagnosis
should take into account all regional, practical, environmental, economical, safety and any other factors
which can be relevant to the prescriptive decisions to be taken.
It is not the purpose of this European Standard to provide a specification, or even guidance in developing
specifications for remedial work to eradicate wood destroying organisms. This European Standard also
does not give guidance on the methods of application or the precise amounts of products that might be
appropriate to apply in specific practical circumstances. It is intended to guide specifiers, users and
others in selecting and specifying products on the basis of their effectiveness as demonstrated in
accordance with the criteria given.

1 Scope
This European Standard 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 European Standard is applicable to all wood preservative products supplied for application in liquid
form for curative uses against attack by wood boring beetles. This European Standard is also applicable
for products applied to prevent the growth of the dry rot fungus through masonry.
This European Standard 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 or as normative annexes to this European Standard.
NOTE 1 For re-testing after making variations in product formulation, guidance is given in Annex A.
NOTE 2 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 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 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.
Annex C (informative) contains a guidance for physical chemical properties.

a) "Hylotrupes bajulus (C-H)" and "Anobium punctatum (C-A)" unless b) or c) is applicable and is
selected; or
b) the more tolerant species, if the product is based on insecticide(s) for which data on curative
efficacy already exist which show different activities against Hylotrupes bajulus and Anobium
punctatum, that is the brv for the less tolerant species is less than 80 % of the brv for the more
tolerant species; or
c) against "Hylotrupes bajulus (C-H)" or "Anobium punctatum (C-A)", if the product is based on
insecticide(s) for which data on the curative efficacy already exist which show more or less equal
activity against both beetle species, that is the brv of the least tolerant beetle species is equal to or
greater than 80 % of the brv of the more tolerant beetle species.
5.1.3 The maximum application rate in the test shall not exceed 300 ml per square meter.
5.1.4 If the curative wood preservative is designed to be used for the protection of items of cultural
heritage for Anobium punctatum, the mortality at the end of the test shall be at least 90 %.
5.2 Requirements for preventive efficacy
Where local conditions require the curative wood preservative product to have also preventive efficacy,
or to support the claims of manufacturers or the demands of specifiers, the product shall have its
preventive efficacy tested in accordance with EN 599-1 at an application rate equal to or lower than that
at which tests were conducted to assess the curative efficacy.
6 Efficacy requirements for barrier treatments against dry rot fungus
The masonry fungicide tested according to CEN/TS 12404 shall prevent the growth of the fungus through
mortar specimens.
7 Derivation of effective values
7.1 Effective value against beetles
The effective value is derived from the results of the biological tests. The manufacturer recommended
application rate shall not be lower than the effective value (see 3.6).

7.2 Effective value against dry rot fungus
The effective value is derived from the results of the biological test and shall be equal to the application
rate of the ready to use formulation of the wood preservative, which prevented fungal growth through
the mortar specimens (no ratings higher than 1).
8 Product identification and labelling
8.1 Product identification
Product identification and control shall be in accordance with EN 599-1.
8.2 Product labelling
8.2.1 General
Wood preservative products shall be labelled according to their efficacy where tested in accordance with
EN 14128.
