EN 338:2016

Structural timber - Strength classes

This European Standard establishes a system of strength classes for general use in design codes.
It gives characteristic strength and stiffness properties and density values for each class to which EN 14081-1 refers.
This standard is applicable to all softwood and hardwood timber for structural use.

Bauholz für tragende Zwecke - Festigkeitsklassen

Diese Europäische Norm legt ein System von Festigkeitsklassen für den allgemeinen Gebrauch in Bemessungsnormen fest.
Sie gibt charakteristische Werte der Festigkeit, Steifigkeit und Rohdichte für jede Klasse an, auf die sich EN 14081 1 bezieht.
Diese Norm gilt für alle Nadel- und Laubhölzer für tragende Zwecke innerhalb des Anwendungsbereiches von EN 14081-1.

Bois de structure - Classes de résistance

La présente Norme européenne établit un système de classes de résistance d'utilisation générale pour les codes de calcul de structures.
Elle donne, pour chaque classe référencée dans l'EN 14081-1, les valeurs caractéristiques des propriétés de résistance et de rigidité, et les valeurs de masse volumique.
La présente norme s'applique à tous les bois résineux et feuillus à usage structurel.

Konstrukcijski les - Trdnostni razredi

Ta evropski standard določa sistem razredov trdnosti za splošno uporabo pri projektnih kodah.. Določa značilne lastnosti trdnosti in togosti ter vrednosti gostote za vsak razred, na katerega se sklicuje EN 14081-1. Ta standard se uporablja za vse mehke in trde vrste lesa za uporabo pri konstrukcijah.
