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

This document specifies a method for leaching, applicable to test specimens of wood or wood-based products which are subsequently subjected to biological tests.
This document 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 can also be used for pre-conditioning of untreated wood, modified wood and wood-based panel products, whether they received preservative treatment or not.

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

Dieses Dokument legt ein Verfahren zur Auswaschbeanspruchung fest, das für Prüfkörper aus Holz oder Holzprodukten anwendbar ist, die anschließend biologischen Prüfungen unterzogen werden.
Dieses Dokument ist anwendbar:
a)   zur Vorbehandlung von Prüfkörpern vor einer biologischen Prüfung; oder
b)   um eine mögliche Abnahme einer Wirksamkeit zu erfassen, indem bei einer biologischen Prüfung von behandelten Prüfkörpern die Eigenschaften von Prüfkörpern, die einem solchen Verfahren ausgesetzt waren, mit Eigenschaften jener Prüfkörper verglichen werden, die keiner Auswaschbeanspruchung ausgesetzt waren.
ANMERKUNG   Dieses Verfahren kann auch zur Vorbehandlung von unbehandeltem Holz, modifiziertem Holz und Holzwerkstoff-Produkten mit oder ohne Zusatz von Holzschutzmitteln verwendet werden.

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 de délavage, applicable aux éprouvettes de bois et de panneaux à base de bois qui sont ultérieurement soumises à des essais biologiques.
Le présent document 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 du bois non traité, du bois modifié et des panneaux à base de bois qu’ils aient ou non reçu un traitement avec un produit de préservation.
