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.
