Durability of wood and wood-based products - Test method against wood destroying basidiomycetes - Part 2: Assessment of inherent or enhanced durability
This document specifies a method of test for determining the natural durability of a timber against wood-destroying basidiomycetes cultured on a malt extract agar medium. The method is applicable to all timber species.
Furthermore this method can be used to test modified wood. The test method described in this document can be applied to specific wood species, commercial supplies of sawn timber, wood-based materials, wood treated with preservatives and modified wood, both thermally and chemically modified wood.
However, this document is not intended to determine the effectiveness of wood preservatives used to prevent decay.
NOTE 1 Determining the efficacy of wood preservatives used to prevent decay is the scope of EN 113-1. However, in addition to this and with some amendments, it might also be possible in some cases to test treated wood using the method described here.
NOTE 2 This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.
Annex A (informative) contains a guidance on sampling.
Annex B (normative) contains some methods of sterilization.
Annex C (informative) contains information on the culture vessels.
Annex D (informative) contains an example of a test report.
Annex E (informative) contains information on the test fungi.
Annex F (informative) contains the assessment of the results.

Durabilité du bois et des matériaux dérivés du bois - Méthode d'essai vis-à-vis des champignons basidiomycètes - Partie 2 : Détermination de la durabilité inhérente ou améliorée
Le présent document décrit une méthode d'essai permettant de déterminer la durabilité naturelle d'un bois vis-à-vis des champignons basidiomycètes lignivores cultivés sur milieu malt-agar. La méthode est applicable à toutes les essences de bois.
En outre, cette méthode peut être utilisée pour soumettre à essai le bois modifié. La méthode d'essai décrite dans le présent document peut être appliquée à des essences spécifiques de bois, aux approvisionnements commerciaux en bois scié, aux matériaux à base de bois, aux bois traités par produit de préservation et aux bois modifiés, tant thermiquement que chimiquement.
Cependant, le présent document n'a pas pour vocation de déterminer l'efficacité d'un produit de préservation du bois utilisé pour empêcher la dégradation fongique.
NOTE 1 La détermination de l'efficacité d'un produit de préservation du bois empêchant la dégradation fongique relève du domaine d'application de l'EN 113-1. Toutefois, outre ceci, et avec quelques modifications, il pourrait également être possible dans certains cas de mettre à essai le bois traité en utilisant la méthode décrite ici.
NOTE 2 Cette méthode peut être utilisée conjointement avec une épreuve de vieillissement, par exemple selon l'EN 73 ou l'EN 84.

Introduction
This document describes a laboratory method of test which gives a basis for the assessment of the
biological durability of a sample of wood or wood product against attack by wood-destroying
basidiomycetes. Specifically the natural durability of a wood species can vary depending on the
conditions of growth such as climate and soil type. For this reason, the durability established using the
method described in this document will relate only to the sample of timber tested. Guidance on sampling
is given in Annex A.
This laboratory method provides one criterion by which the durability of the timber can be assessed. It
is recommended that this information is supplemented by data from other relevant tests, and above all
by practical experience.
The procedures described in this standard method are intended to be carried out by suitably trained or
supervised specialists.
1 Scope
This document specifies a method of test for determining the natural durability of a timber against wood-
destroying basidiomycetes cultured on a malt extract agar medium. The method is applicable to all timber
species.

can be applied to specific wood species, commercial supplies of sawn timber, wood-based materials,
wood treated with preservatives and modified wood, both thermally and chemically modified wood.
