Foreword
This document (EN 73:2014) 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text or by endorsement, at the latest by April 2015 and conflicting national standards shall be withdrawn at the
latest by April 2015.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 73:1988.
Compared to EN 73:1988 the following modifications have been made:
a) an Introduction has been added;
b) grids have been introduced in 5.1 to carry the test specimens.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,

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 European Standard provides a laboratory based method for ageing test blocks which are to be subject to
biological testing.
1 Scope
This European Standard specifies an evaporative ageing procedure, applicable to test specimens of wood
which have been previously treated with a wood preservative, in order to evaluate any loss of effectiveness
when these test specimens are subsequently subjected to biological tests.
2 Principle
Test specimens are prepared for biological testing of the effectiveness of wood preservatives against either
fungi or insects using the appropriate standards methods. Test specimens are exposed, for a specified period,
in a dust-free current of air of a defined velocity and temperature.
3 Equipment
3.1 A wind tunnel which is compartmented and fitted with devices for heating and distributing air.
The air shall be dust-free and shall not be polluted by chemical products which coul
