EN 599-1:2009

Durability of wood and wood-based products - Efficacy of preventive wood preservatives as determined by biological tests - Part 1: Specification according to use class

This part of EN 599 specifies for each of the five use classes defined in EN 335-1, the biological tests required for evaluating the efficacy of wood preservatives for the preventive treatment of solid timber, together with the minimum ageing tests required for the respective use class. It provides the method for calculating the critical value of a preservative. The critical value is the value that shall be used to calculate the recommended retention of the preservative appropriate for specific service conditions. The critical value is not necessarily the recommended retention or the minimum retention level for the preservative. The wide range of hazards, exposure conditions and service life requirements across Europe make it necessary to allow for local considerations in the calculation of the required preservative retention; EN 351-1 provides for the critical value to be adjusted to take account of these factors.
This part of EN 599 is applicable to all wood preservative products supplied for application in liquid form for the preventive treatment of timbers (structural and non-structural) against wood-attacking fungi, wood-attacking insects and marine borers as described in EN 335-1. However, it is applicable to products for preventive treatments against fungi causing disfigurement (blue stain) of wood in service if this forms part of the overall preventive efficacy of the product.
This part of EN 599 does not necessarily take into account all the factors which may affect the stability of active ingredients in preservative treated wood. These factors include ultra-violet light and microbiological agencies capable of degrading components of the preservative. Such factors are an integral part of exposure in field trials but are subject to natural variation and their impact is not directly assessed in the field trial methods included in this standard.

Dauerhaftigkeit von Holz und Holzprodukten - Wirksamkeit von Holzschutzmitteln wie sie durch biologische Prüfungen ermittelt wird - Teil 1: Spezifikation entsprechend der Gebrauchsklasse

Dieser Teil von EN 599 legt für jede der fünf in EN 335-1 definierten Klassen die erforderlichen biologischen
Prüfungen fest, die in Verbindung mit den erforderlichen Mindestalterungsprüfungen für die entsprechende
Gebrauchsklasse, zur Bewertung der Wirksamkeit von Holzschutzmitteln zur vorbeugenden Behandlung von
Vollholz notwendig sind. Er stellt ein Verfahren zur Berechnung der Mindestmenge eines Schutzmittels zur
Verfügung. Die Mindestmenge ist der Wert, der dazu verwendet werden muss, die empfohlene Aufnahme des
Schutzmittels für bestimmte Gebrauchsbedingungen zu berechnen. Die Mindestmenge ist nicht notwendigerweise
die empfohlene Aufnahme oder der Mindestaufnahmegrad des Schutzmittels. Das große
Spektrum an Gefährdungen, Expositionsbedingungen und die europaweiten Anforderungen an die
Gebrauchsdauer erfordern es, dass örtliche Gegebenheiten bei der Berechnung der erforderlichen Schutzmittelaufnahme
berücksichtigt werden; EN 351-1 stellt die Mindestmenge zur Verfügung, die angepasst
werden kann, um diese Faktoren zu berücksichtigen.
Dieser Teil von EN 599 kann für alle Holzschutzmittelprodukte angewendet werden, die für eine Anwendung
in flüssiger Form zur vorbeugenden Behandlung von Hölzern (tragend und nicht tragend) gegen Holz
zerstörende Pilze vorgesehen sind, sowie gegen Holz zerstörende Insekten und gegen marine Organismen,
wie in EN 335-1 beschrieben ist. Für Produkte zur vorbeugenden Behandlung gegen Holz verfärbende Pilze
an verarbeitetem Holz (Bläue) ist er jedoch anwendbar, wenn dies Bestandteil der gesamten vorbeugenden
Wirkung des Produktes ist.
Dieser Teil von EN 599 berücksichtigt nicht notwendigerweise alle Faktoren, die die Stabilität der Wirkstoffe in
schutzmittelbehandeltem Holz beeinflussen können. Diese Faktoren umfassen ultraviolettes Licht und
mikrobiologische Organismen, die Bestandteile des Schutzmittels abbauen können.

Durabilité du bois et des matériaux dérivés du bois - Efficacité des produits préventifs de préservation du bois établie par des essais biologiques - Partie 1: Spécification par classe d'emploi

La présente partie de l'EN 599 prescrit pour chacune des cinq classes d’emploi définies dans l'EN 335-1, les
essais biologiques requis pour l’évaluation de l’efficacité des produits de préservation appliqués dans le
traitement préventif du bois massif, avec les épreuves de vieillissement minimales exigibles par classe
d’emploi. Elle fournit la méthode de calcul de la valeur critique d’un produit de préservation. La valeur critique
est la valeur qui doit être utilisée pour calculer la rétention recommandée du produit de préservation approprié
dans des conditions de service spécifiques. La valeur critique ne correspond pas nécessairement à la
rétention recommandée ou au niveau de rétention minimale du produit de préservation. La large gamme
d’exigences relatives aux risques, conditions d’exposition et durée de vie applicables en Europe requiert de
tenir compte des considérations locales dans le calcul de la rétention requise des produits de préservation.
L’EN 351-1 prévoit d’ajuster la valeur critique pour tenir compte de ces facteurs.
La présente partie de l'EN 599 est applicable à toutes les formulations de produit de préservation du bois
devant être appliquées sous forme liquide pour le traitement préventif des bois (utilisés ou non en structure)
contre l'attaque des champignons attaquant le bois, des insectes xylophages et des térébrants marins, tels
que décrits dans l'EN 335-1. Toutefois, elle est applicable aux produits pour les traitements préventifs contre
les champignons de discoloration (bleuissement) du bois en service si cela est inclus dans l'efficacité
préventive globale du produit.

Foreword
This document (EN 599-1:2009) 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 January 2010, and conflicting national standards shall be withdrawn at
the latest by January 2010.
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 599-1:1996.
Significant technical differences between this edition and EN 599-1:1996 are as follows:
 The scope now emphasises that this standard is not a performance standard but a standard for
characterising the efficacy of wood preservatives, based on data derived from the biological tests that it
specifies, supplemented by, in certain cases, data from field tests. This European Standard provides a
basis for establishing preservative retentions for timber when specified in conjunction with EN 351-1
taking into account necessary local considerations. It points out that at present not all natural ageing
factors which may affect the stability of active ingredients for wood preservatives can be assessed by
standardized methods but have nevertheless to be taken into account in the development of preservative
products capable of being effective in service. It also allows for preservatives that have been used
successfully and legally before the standard was to have their efficacy confirmed in accordance with the
general principles of the standard (so called “grandfather-clause”).
 This document now provides for the use of data from CEN/TS 839, in specific cases, as a method for the
assessment of preservatives designed for superficial applications.
 In Annex A “Guidance on re-testing after making variations in product formulation”, requirements have
been clarified by the provision of diagrams.
 Production control has been withdrawn from Clause 9 and transferred to a new informative annex (now
Annex B).
 A new normative annex on the validity of test results from former standards after their revision has been
added (now Annex H).
EN 599 consists of two parts. Part 2 (EN 599-2, Durability of wood and wood-based products —
Performance of preventive wood preservatives as determined by biological tests — Part 2: Classification
and labelling) will be revised later once the exact requirements of the Biocidal Products Directive have been
finalised.
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, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
This part of EN 599 is one of a series and should be used in conjunction with EN 599-2, EN 335-1 and
EN 335-2, which describe the service conditions for treated wood in terms of use classes, and EN 351-1,
which describes a classification system for preservative treated wood in terms of preservative penetration and
gives guidance on classes for retentions. The need for wood preservatives depends in part on the natural
durability of the wood and therefore this part of EN 599 should also be used in conjunction with EN 350-1,
EN 350-2 and EN 460.
