Durability of wood and wood-based products - Determination of emissions from preservative treated wood to the environment - Wooden commodities exposed in Use Class 3 (Not covered, not in contact with the ground) - Semi-field method
This European Standard specifies a method for determining the leaching of active ingredients or other compounds from preservative treated wood by a semi field method for Use Class 3 (outdoor above ground). The preservative treated wood can be tested with or without subsequently surface coating or other water-repellent treatment. The method is applicable to the testing of commercial or experimental preservatives or paint systems applied to non-durable timber by methods appropriate to commercial practice.

Diese Technische Spezifikation legt ein Verfahren zur Bestimmung der Auswaschung von Wirkstoffen oder sonstigen Verbindungen aus dem behandelten Holz durch ein Semi-Feldverfahren für Holzprodukte der Gebrauchsklasse 3 (im Freien, nicht abgedeckt, ohne Erdkontakt) fest. Das mit Holzschutzmittel behandelte Holz kann mit oder ohne nachfolgende Oberflächenbeschichtung oder sonstige wasserabweisende Behandlung geprüft werden. Das Verfahren gilt für die Prüfung handelsüblicher oder experimenteller Holzschutzmittel oder Anstrichsysteme, die nach in der gewerblichen Praxis üblichen Verfahren auf Holz aufgetragen werden.

Cette spécification technique européenne décrit une méthode de détermination du délavage de matières actives ou d'autres composés issus du bois traité avec des produits de préservation par une méthode semi-terrain pour classe d'emploi 3 (à l'extérieur au-dessus du sol). Le bois traité avec des produits de préservation peut être soumis à essai avec ou sans revêtement de surface ou traitement hydrofuge ultérieur. La méthode s'applique à l'essai de produits de préservation ou de systèmes de peinture au stade commercial ou expérimental, appliqués sur des bois non durables par des méthodes adaptées aux pratiques du commerce.

Ta evropski standard določa metodo za določevanje izpiranja aktivnih sestavin ali drugih spojin z zaščitenega lesa z delno terensko metodo za 3. razred uporabe (na prostem nad tlemi). Zaščiteni les se lahko preskuša z ali brez naknadnega površinskega premazovanja ali druge obdelave, ki les zaščiti pred vodo. Metoda se uporablja za preskušanje komercialnih in eksperimentalnih zaščitnih sredstev ali barvnih sistemov, ki se jih nanese na neobstojni les z metodami, primernimi za komercialno prakso.

Introduction
The leaching from preservative treated wood into the environment needs to be quantified to enable an
environmental risk assessment to be made of the treated wood, e.g. according to the Biocidal Products
Regulation, 528/2012. This document describes a semi-field method for the determination of leachate
from preservative treated wood where the preservative treated wood is not covered and not in contact
with the ground or water (use class 3 according to EN 335).
The method is a semi-field procedure for obtaining water samples (leachate) from treated wood
exposed out of ground contact, during natural exposure. The quantities of emissions in the leachate are
related to the surface area of the wood and can be used in scenarios for the environmental risk
assessment of the treated wood.
NOTE The leachate can also be tested for eco-toxicological effects (example: OECD 202 testing on Daphnia
sp.).
1 Scope
This Technical Specification specifies a method for determining the leaching of active ingredients or
other compounds from treated wood by a semi-field method for use class 3 (outdoor above ground).
The preservative treated wood can be tested with or without subsequently surface coating or other
water-repellent treatment. The method is applicable to the testing of commercial or experimental
preservatives or paint systems applied to timber by methods appropriate to commercial practice.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3)
3 Description of the test method
3.1 Principle
Panels are treated, assembled and placed outdoors, out of ground contact and exposed to the normal
environmental and ecological factors which affect preservative treated wood so exposed in practice.
The rainwater is retained and the leachate is monitored by chemical analyses of the active ingredients
and/or other compounds.
3.2 Quality criteria
The validity of the analytical method for the substances in question should be determined before
conducting the test:
a) accuracy;
b) specificity;
c) limit of detection (LOD);
d) limit of quantification (LOQ);
e) precision.
NOTE 1 EN ISO 5667-3 may give guidance on the preservation and handling of water samples.
NOTE 2 This may include CAS no or chemical formulation.
3.3 Wood preservative
The test report shall state the name and other designation of the tested product, and the trade or
common name of the active ingredient(s) as defined in the regulation n°528/2012.
Use of a coating is possible (identity and amount of coating used shall be stated in the test report).
3.4 Apparatus
3.4.1 Vessel for receiving water
Laboratory brown glass flask or plastic jars with no impurities that can influence the active ingredient.
NOTE EN ISO 5667-3 gives the good practices to preserve water samples.
