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

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.

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

Dieses Dokument legt die Mindestleistungsanforderungen in biologischen Prüfungen für Produkte zur bekämpfenden Behandlung gegen bestimmte Holz zerstörende Organismen fest. Es 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.
Dieses Dokument gilt für alle Holzschutzmittel, die zur Anwendung in flüssiger Form für Bekämpfungsmaßnahmen gegen Holz zerstörende Käfer geliefert werden. Dieses Dokument gilt auch für Produkte zur Verhinderung des Durchwachsens von Echtem Hausschwamm durch Mauerwerk.
Dieses Dokument 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 vorliegen.
ANMERKUNG   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).
Dieses Dokument gilt nicht für Produkte, die als Gase eingesetzt werden.
Dieses Dokument 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.

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

Le présent document spécifie les exigences minimales de performance dans des essais biologiques des produits curatifs contre des organismes lignivores spécifiques. Il 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.
Le présent document s'applique à toutes les formulations de produit de préservation du bois destinées à être mises en œuvre sous forme liquide pour le traitement curatif des bois vis-à-vis des coléoptères xylophages. Le présent document s'applique également aux produits utilisés pour empêcher le développement de la mérule au travers de la maçonnerie.
Il s'applique aussi aux produits curatifs mis en œuvre 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.
NOTE   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) N° 528/2012 sur l'utilisation des produits biocides.
Le présent document n'est pas applicable aux produits utilisés en fumigation.
Le présent document 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.

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 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.
