Field test method for determining the relative protective effectiveness of a wood preservative in ground contact

This European Standard specifies a field test method for evaluating the effectiveness of wood preservatives in a ground contact situation. Wood treated with a reference preservative is included for comparison.
The protective effect of the test preservative is assessed in relation to the effect of a reference wood preservative applied by a specified treatment.

Freiland-Prüfverfahren zur Bestimmung der relativen Schutzwirkung eines Holzchutzmittels im Erdkontakt

Diese Europäische Norm legt ein Freiland-Prüfverfahren zur Bewertung der Wirksamkeit von Holzschutzmitteln bei Erdkontakt fest. Zum Vergleich wird mit einem Referenzschutzmittel behandeltes Holz eingesetzt.
Die Schutzwirkung des zu prüfenden Holzschutzmittels wird bewertet in Bezug auf die Wirkung eines Referenz-Holzschutzmittels, das mithilfe eines festgelegten Behandlungsverfahrens eingebracht wurde.

Essai de champ pour déterminer l'efficacité protectrice relative d'un produit de préservation du bois en contact avec le sol

La présente Norme européenne décrit une méthode d'essai de champ permettant d'évaluer l'efficacité des produits de préservation du bois dans une situation de contact avec le sol. Du bois traité avec un produit de préservation de référence est inclus à des fins de comparaison.
L'effet protecteur du produit de préservation soumis à essai est déterminé comparativement à celui d'un produit de préservation du bois de référence appliqué selon une méthode normalisée.
