Wood preservatives - Determination of the protective effectiveness against wood destroying basidiomycetes - Application by surface treatment

This European Standard specifies a method of test for the determination of the protective effectiveness of a wood preservative, applied to the surface of the wood, against wood destroying basidiomycetes cultured on an agar medium.
The method is applicable to all products which are to be applied by superficial application processes. This includes :
-   organic solvent-based wood preservatives ; or
-   organic water-dispersible formulations, as supplied or as prepared in the laboratory by dilution of concentrates ; or
-   water-soluble products ; or
-   chemicals which are being studied as active ingredients for application by superficial processes.
NOTE   This method may be used in conjunction with an ageing procedure, for example EN 73.

Holzschutzmittel - Bestimmung der vorbeugenden Wirksamkeit gegen holzzerstörende Basidiomyceten - Anwendung mit Oberflächenverfahren

Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung der vorbeugenden Wirksamkeit eines auf die
Holzoberfläche aufgebrachten Holzschutzmittels gegen auf einem Agarmedium gezüchtete holzzerstörende
Basidiomyceten fest.
Das Verfahren ist auf alle Produkte anwendbar, die für die Anwendung mit Oberflächenverfahren bestimmt
sind. Dazu gehören:
- Holzschutzmittel auf der Grundlage organischer Lösemittel;
- wasserdispergierbare organische Formulierungen im Anlieferungszustand oder in der Form, in der sie im
Laboratorium durch Verdünnung von Konzentraten hergestellt werden;
- wasserlösliche Produkte;
- Chemikalien, die als Wirkstoffe für die Anwendung mit Oberflächenverfahren untersucht werden.
ANMERKUNG Dieses Verfahren kann in Verbindung mit einer Alterungsbeanspruchung, z. B nach EN 73, angewendet
werden.

Produits de préservation du bois - Détermination de l'efficacité protectrice vis-à-vis des champignons basidiomycètes lignivores - Application par traitement de surface

La présente Norme européenne spécifie une méthode d’essai de la détermination de l’efficacité protectrice d’un produit de préservation du bois, appliqué par un traitement de surface, vis-à-vis des champignons basidiomycètes lignivores cultivés sur milieu gélosé.
Cette méthode est applicable à tous les produits destinés à être appliqués par des procédés par application superficielle. Cela comprend :
- les produits de préservation du bois solubles dans les solvants organiques ; ou
- des émulsions telles qu’elles sont livrées ou préparées en laboratoire à partir de concentrés ; ou
- des produits hydrosolubles ; ou
- des produits chimiques étudiés en tant que matières actives pour l’application par des procédés de surface.
NOTE Cette méthode peut être utilisée conjointement à une épreuve de vieillissement, par exemple celle décrite dans l’EN 73.
