Wood preservatives - Determination of preventive action against Reticulitermes species (European termites) (Laboratory method)
This document specifies a method for the determination of the preventive action of a wood preservative against the Reticulitermes species of European termites when the preservative is applied as a surface treatment to wood.
NOTE 1 This method can be applied not only to different species of Reticulitermes, but also to other species of the family Rhinotermitidae, where necessary adapting the temperature and humidity conditions and the assessment of attack to the specific behaviour of the species concerned.
This method is applicable to:
— water-insoluble chemicals which are being studied as active ingredients;
— organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates;
— organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; and
— water-soluble materials, for example salts.
NOTE 2 This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.
Holzschutzmittel - Bestimmung der vorbeugenden Wirkung gegenüber Reticulitermes-Arten (Europäische Termiten) (Laboratoriumsverfahren)
Dieses Dokument legt ein Verfahren zur Bestimmung der vorbeugenden Wirkung eines Holzschutzmittels gegenüber europäischen Reticulitermes-Arten fest, wobei das Holzschutzmittel zur Oberflächenbehandlung von Holz angewendet wird.
ANMERKUNG 1 Das Verfahren kann nicht nur auf verschiedene Arten von Reticulitermes, sondern auch auf andere Arten der Familie Rhinotermitidae angewendet werden, indem gegebenenfalls die Temperatur- und Feuchtebedingungen und die Bewertung des Angriffs entsprechend dem spezifischen Verhalten der betrachteten Art angepasst werden.
Dieses Verfahren ist anwendbar für:
- wasserunlösliche Chemikalien, die als Wirkstoffe untersucht werden;
- organische Formulierungen im Anlieferungszustand oder in Form von im Laboratorium hergestellten Verdünnungen von Konzentraten;
- organische, in Wasser dispergierbare Formulierungen im Anlieferungszustand oder in der Form, wie sie im Laboratorium durch Verdünnung von Konzentraten hergestellt werden; und
- wasserlösliche Stoffe, zum Beispiel Salze.
ANMERKUNG 2 Dieses Verfahren kann in Verbindung mit einer Alterungsbeanspruchung, z. B. EN 73 oder EN 84, angewendet werden.
Produits de préservation des bois - Détermination de l'action préventive contre les espèces de Reticulitermes (termites européens) (Méthode de laboratoire)
Le présent document décrit une méthode pour la détermination de l'action préventive d'un produit de préservation du bois contre les espèces de termites européens du genre Reticulitermes quand le produit de préservation s'applique au bois par un traitement de surface.
NOTE 1 Cette méthode peut être appliquée non seulement à différentes espèces de Reticulitermes, mais aussi à d'autres espèces de la famille des Rhinotermitidae, en adaptant si nécessaire les conditions de température et d'humidité et l'évaluation de l'attaque au comportement spécifique de l'espèce concernée.
Cette méthode s'applique :
- aux produits chimiques non hydrosolubles étudiés en tant que matières actives ;
- aux formulations organiques telles qu'elles sont fournies ou préparées au laboratoire par dilution de concentrés ;
- aux formulations organiques hydrodispersables telles qu'elles sont fournies ou préparées au laboratoire par dilution de concentrés ; et
- aux produits hydrosolubles, par exemple des sels.
NOTE 2 Cette méthode peut être utilisée conjointement avec une épreuve de vieillissement, par exemple selon l'EN 73 ou l'EN 84.

Introduction
This document describes a laboratory method of testing which gives a basis for assessment of the effectiveness
of a wood preservative, when applied as a surface treatment, against the Reticulitermes species of European
termites.
This laboratory method provides one criterion by which the value of a product can be assessed. It is further
recommended that results from this test should be supplemented by those from other appropriate tests, and
above all by comparison with practical experience.
When products which are very active at low concentrations are used it is very important to take suitable
precautions to isolate and separate, as far as possible, operations involving chemical products, other products,
treated wood, laboratory apparatus and clothing. Suitable precautions should include the use of separate
rooms, areas within rooms, extraction facilities, conditioning chambers and special training for personnel (see
also Annex C for environmental, health and safety precautions).
