European foreword
This document (EN 113-1:2020) 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 June 2021, and conflicting national standards shall be
withdrawn at the latest by June 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 113:1996 and EN 113:1996/A1:2004.
Test results obtained with earlier versions of EN 113 are still valid.
Compared to EN 113:1996 and EN 113:1996/A1:2004 the following major changes have been
introduced:
— This is now a first part of EN 113 corresponding to the EN 113:1996 document. Other parts relate
to a different scope.
— The title is changed;
— The obligatory fungi are indicated differently;
— The calculation of a correction factor (C) has been differently included;
— The methods for sterilization are updated;
— All annexes are informative except Annex B;
— Some additional validity requirements are introduced for control specimens.
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
This document describes a laboratory method of test, which gives a basis for the assessment of
effectiveness of a wood preservative against wood destroying basidiomycetes. By using this method it is
possible to determine the loading at which impregnated wood of a susceptible species can regarded as
adequately protected under the conditions of test.
This laboratory method p
