Plywood - Specifications
This European Standard specifies the requirements for plywood for general purposes or structural application in dry, humid or exterior conditions. It also gives a classification system based on the bending properties.
NOTE 1 This standard will be called up in EN 13986 for construction applications.
The values listed in this standard relate to product properties but they are not characteristic values to be used in design calculations.
NOTE 2 Such characteristic values (e. g. for use in design calculation in ENV 1995-1-1) are given either in prEN 12369-2 or by the manufacturer, based on testing according to EN 789, EN 1058 and ENV 1156.
Additional information on supplementary properties for certain applications is also given.
Sperrholz - Anforderungen
Diese Europäische Norm legt Anforderungen an Sperrholz für allgemeine oder tragende Zwecke zur Verwendung im Trocken-, Feucht- oder Außenbereich fest. Sie enthält außerdem ein Klassifizierungssystem auf der Grundlage der Biegeeigenschaften.
ANMERKUNG 1 Auf diese Norm wird in EN 13986 für Anwendungen im Bauwesen Bezug genommen.
Die in dieser Norm angegebenen Werte beziehen sich auf Produkteigenschaften; es sind keine charakteristischen Werte, die für konstruktive Berechnungen verwendet werden können.
ANMERKUNG 2 Solche charakteristischen Werte (z. B. für konstruktive Berechnungen in ENV 1995-1-1) sind entweder in prEN 12369-2 angegeben oder werden durch Prüfung nach EN 789, EN 1058 und ENV 1156 ermittelt und durch den Hersteller angegeben.
Sie enthält zusätzliche Informationen über weitere Eigenschaften für bestimmte Verwendungszwecke.

Theseconditions correspond with service class 1 according to ENV 1995-1-1.Boards of this type are suitable for use in biological hazard class 1 of EN 335-33.2plywood for use in humid conditions (EN 636-2)plywood to be used in conditions characterised by a moisture content in the material corresponding to a tempera-ture of 20 °C and relative humidity of the surrounding air only exceeding 85 % for a few weeks per year. Theseconditions correspond with service class 2 according to ENV 1995-1-1.Boards of this type are suitable for use in biological hazard class 1 and 2 of EN 335-3NOTEThis plywood is appropriate for protected external applications (e.g. behind cladding or under roof coverings), but isalso capable of resisting weather exposure for short periods (e.g.
when exposed during the construction). It is also suitable forinterior situations where the service moisture condition is raised above humidity of dry conditions.3.3plywood for use in exterior conditions (EN 636-3)plywood to be used in climatic
