Oriented Strand Boards (OSB) - Definitions, classification and specifications
This European Standard applies to Oriented Strand Boards (OSB). It defines terms, establishes a
classification and specifies requirements.
The values listed in this European Standard relate to product properties but they are not characteristic values to be used in design calculations.
NOTE Test methods for determination of mechanical properties for structural purposes are given in EN 789.
Determination of characteristic values of mechanical properties and density for structural purposes is given in EN 1058. Design characteristic values for OSB are given in EN 12369-1.
Information on supplementary properties is given in Annex C.
Platten aus langen, flachen, ausgerichteten Spänen (OSB) - Definitionen, Klassifizierung und Anforderungen
Diese Europäische Norm gilt für Platten aus langen, flachen, ausgerichteten Spänen (OSB). Sie definiert
Begriffe, stellt eine Klassifizierung auf und legt Anforderungen an diese Platten fest.
Die in dieser Europäischen Norm angegebenen Werte beziehen sich auf Produkteigenschaften, es sind keine charakteristischen Werte zur Verwendung für konstruktive Berechnungen.
ANMERKUNG Prüfverfahren zur Bestimmung mechanischer Eigenschaften für tragende Zwecke sind in EN 789 angegeben. Die Bestimmung der charakteristischen Werte der mechanischen Eigenschaften und der Rohdichte für tragende Zwecke enthält EN 1058. Charakteristische Werte zur Berechnung und Bemessung für OSB sind in EN 12369-1 angegeben.
Sie enthält im Anhang C zusätzliche Informationen über weitere Eigenschaften.
Panneaux de lamelles minces, longues et orientées (OSB) - Définitions, classification et exigences
La présente norme européenne s’applique aux panneaux de lamelles minces, longues et orientées (OSB).
Elle donne des définitions, établit une classification et prescrit les exigences des panneaux.
Les valeurs données dans la présente norme européenne concernent les caractéristiques du produit mais ne
sont pas les valeurs caractéristiques à utiliser dans les calculs de conception.
NOTE Les méthodes d’essai pour la détermination des caractéristiques mécaniques pour des emplois en structure
sont données dans l’EN 789. La détermination des valeurs caractéristiques des caractéristiques mécaniques et de la
masse volumique pour des emplois en structure est donnée dans l’EN 1058. Les valeurs caractéristiques de conception
pour les panneaux OSB sont données dans l’EN 12369-1.
Des informations sur des caractéristiques complémentaires sont données dans l’Annexe C.
