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.

European foreword
This document (EN 73:2020) has been prepared by Technical Committee CEN/TC 38 “Durability of wood
and wood-based products”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2021, and conflicting national standards shall
be withdrawn at the latest by February 2021.

Compared to EN 73:2014 the following modifications have been made:
— change of title;
— inclusion of untreated wood, modified wood and wood-based panel products in the Scope;
— inclusion of a statement regarding the maximum period of time permitted between the completion
of the ageing procedure and the start of the biological test procedure;
— inclusion of a requirement that this period of time be stated in the biological test report.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,

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.
1 Scope
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.
