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

This document specifies an evaporative ageing procedure, applicable to test specimens of wood and wood-based products which are subsequently subjected to biological tests.
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 - Verdunstungsbeanspruchung

Dieses Dokument legt ein Verfahren zur Verdunstungsbeanspruchung fest, das für Prüfkörper aus Holz oder Holzprodukten anwendbar ist, die anschließend biologischen Prüfungen unterzogen werden.
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 d'évaporation

Le présent document spécifie une méthode d'évaporation, applicable aux éprouvettes de bois et de panneaux à base de bois qui sont ultérieurement soumises à des essais biologiques.
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.

Introduction

During its service life, preservative-treated wood can be exposed to conditions which may cause the

volatilization and removal of the wood preservative thereby reducing its effectiveness.

This document provides a laboratory based method for ageing test specimens which are to be subject to

biological testing.
