(Main)Structural timber - Strength classes
Structural timber - Strength classes
This Standard establishes a system of strength classes for general use in structural codes. It gives characteristic strength and stiffness properties and density values for each class and the rules for the allocation of timber populations (i.e. combinations of species, grade and source) to the classes. This standard applies to all softwood and hardwood timber for structural use.
Bauholz für tragende Zwecke - Festigkeitsklassen
Diese Norm legt ein System von Festigkeitsklassen für den allgemeinen Gebrauch in Baunormen fest. Sie gibt charakteristische Werte der Festigkeit und Steifigkeit und Rohdichtewerte für jede Klasse sowie Regeln für die Zuordnung von Holzgrundgesamtheiten (d.h. Kombinationen von Holzart, Herkunft und Sortierklasse) zu den Klassen an. Diese Norm gilt für alle Nadel- und Laubhölzer für tragende Zwecke.
Bois de structure - Classes de résistance
Cette norme établit un système de classes de résistance d'usage général dans le cadre des codes de structure. Elle, indique pour chaque classe, les valeurs caractéristiques des propriétés mécaniques et la masse volumique, ainsi que les règles de classement des populations de bois (c'est-à-dire les combinaisons d'essences, de provenance et de qualités). Cette norme s'applique à tous les bois feuillus ou résineux à usage structurel.
