Durability of wood and wood-based products - Accelerated ageing of treated wood prior to biological testing - Leaching procedure

This document specifies a method for the leaching of test specimens of wood which are used in the testing of the biological efficacy of wood preservatives.
This standard is applicable to:
a)   the pre-conditioning of test specimens prior to their being subjected to a biological test ; or
b)   assessment of loss of effectiveness by comparing the performance in a biological test of treated test specimens subjected to this procedure with others that have not undergone any leaching procedure.
NOTE   The method may also be used for pre-conditioning of wood-based panel products which may or may not have received preservative treatment.

Dauerhaftigkeit von Holz und Holzprodukten - Beschleunigte Alterung von behandeltem Holz vor biologischen Prüfungen - Auswaschbeanspruchung

Dieses Dokument legt ein Verfahren zur Auswaschbeanspruchung von Prüfkörpern, die zur Bestimmung der biologischen Wirksamkeit von Holzschutzmitteln verwendet werden, fest.
Dieses Verfahren ist anwendbar:
a)   für die Alterung der Prüfkörper vor einer biologischen Prüfung; oder
b)   um eine mögliche Abnahme der Wirksamkeit des Holzschutzmittels zu erfassen, indem diese Prüfkörper in biologischen Prüfungen im Vergleich zu anderen Prüfkörpern, die keiner Auswaschbeanspruchung ausgesetzt waren, verwendet werden.
ANMERKUNG   Dieses Verfahren darf auch zur Vorbehandlung von Holzwerkstoff-Produkten eingesetzt werden, die mit oder ohne Zusatz von Holzschutzmitteln hergestellt wurden.

Durabilité du bois et des produits dérivés - Épreuves de vieillissement accéléré des bois traités avant essais biologiques - Épreuve de délavage

Le présent document spécifie une méthode pour le délavage d'éprouvettes de bois qui sont utilisées dans les essais biologiques d'efficacité des produits de préservation du bois.
La présente norme est applicable pour :
a)   le préconditionnement des éprouvettes avant leur soumission ultérieure à un essai biologique ; ou
b)   l'évaluation de la perte de l'efficacité par comparaison dans un essai biologique, de la performance des éprouvettes traitées soumises à cette épreuve par rapport à d'autres n'ayant subi aucune épreuve de délavage.
NOTE   La méthode peut aussi être utilisée pour le préconditionnement des panneaux à base de bois qui peuvent ou non avoir reçu un traitement avec un produit de préservation.
