European foreword
This document (EN 15119-1:2025) has been prepared by Technical Committee CEN/TC 38 “Biological
durability of wood and wood-based products”, the secretariat of which is held by SIS.
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 January 2026, and conflicting national standards shall
be withdrawn at the latest by January 2026.
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 CEN/TS 15119-1:2018.
This document is a revision of the Technical Specification published in 2018. The main changes from the
Technical Specification are that the document is changed into a standard because this laboratory method
is now well known. Furthermore, the basic principles of this document shall remain in line with the OECD
texts (see reference [7] of the Bibliography.)
EN 15119 is composed of the following parts:
— Part 1: Wood held in the storage yard after treatment and wooden commodities exposed in Use Class 3
(not covered, not in contact with the ground) — Laboratory method
— Part 2: Wooden commodities exposed in Use Class 4 or 5 (in contact with the ground, fresh water or sea
water) — Laboratory method
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
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,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
Test results obtained with earlier versions of this method (i.e. CEN/TS 15119-1:2018) are still valid.
The emissions from preservative treated wood into the environment need to be quantified to enable an
environmental risk assessment to be made of the treated wood. This document specifies a laboratory
method for the determination of emissions by leaching from preservative treated wood where the
preservative treated wood is not covered and not in contact with the ground or the water. There are two
situations in this case where such emissions could enter the environment:
a) emissions from preservative treated wood stored outside in the storage yard of a preservative
treatment site. Rain falling on the treated wood could produce emissions that run off into surface
water and / or soil;
b) emissions from treated wood used in commodities exposed in Use Class 3. This is the situation in
which the wood or wood-based product is not covered and not in contact with the ground. It is either
continually exposed to the weather or is protected from the weather but subject to frequent wetting.
Use classes are specified in EN 335 and categorize the biological hazard to which the treated
commodity will be subjected. The Use Classes also specify the situation in which the treated
commod
