Timber structures - Testing of joints made with mechanical fasteners - Requirements for timber density (ISO 8970:2020)

This document specifies a method based on density, for the selection of pieces of wood used in determining the strength and stiffness properties of joints between members of structural timber made with mechanical fasteners. It is intended to be used in conjunction with a test standard specifying a test method.
It is assumed that the wood pieces are conditioned to the relevant conditions, that the wood density is normally distributed and that any deviations are reported.
This document is applicable only to specimens of structural timber.
NOTE    It is emphasized that the wood density is only one of the properties that can influence the strength of a joint. Other relevant properties are, for example, growth-ring size and orientation, toughness and hardness.

Holzbauwerke - Prüfung von mechanischen Verbindungen - Anforderungen an die Rohdichte des Holzes (ISO 8970:2020)

Dieses Dokument legt ein Verfahren fest, bei dem Holzstücke zur Bestimmung der Festigkeits  und Steifigkeitseigenschaften von Verbindungen zwischen Holzelementen für tragende Zwecke mit mecha-nischen Verbindungsmitteln auf der Grundlage der Rohdichte ausgewählt werden. Die Anwendung ist zusammen mit einer Prüfnorm, die ein Prüfverfahren festlegt, vorgesehen.
Es wird vorausgesetzt, dass eine Konditionierung der Holzstücke bei den relevanten Bedingungen erfolgt, dass die Holzrohdichte normalverteilt ist und dass alle Abweichungen bekannt sind.
Dieses Dokument bezieht sich nur auf Probekörper aus Holz für tragende Zwecke.
ANMERKUNG Es wird besonders darauf hingewiesen, dass die Holzrohdichte nur eine der Eigenschaften ist, die die Tragfähigkeit einer Verbindung beeinflussen können. Andere diesbezügliche Eigenschaften sind z. B. Jahresringbreite und  ausrichtung, Belastbarkeit und Härte.

Structures en bois - Essai sur assemblages réalisés par organes mécaniques - Exigences concernant la masse volumique du bois (ISO 8970:2020)

Le présent document spécifie une méthode de prélèvement, basée sur la masse volumique, des pièces de bois utilisées pour déterminer les propriétés de résistance et de rigidité des assemblages d'éléments structuraux en bois réalisés par des organes mécaniques. Elle est destinée à être utilisée conjointement avec une norme d'essai spécifiant une méthode d'essai.
Il est supposé que les pièces de bois sont conditionnées conformément aux conditions applicables, que la masse volumique du bois est distribuée selon une loi normale et que tout écart est consigné.
Le présent document s'applique uniquement aux échantillons de bois de structure.
NOTE       Il est souligné que la masse volumique du bois n'est qu'une des propriétés pouvant avoir une incidence sur la résistance d'un assemblage. D'autres propriétés concernées sont, par exemple, la taille et l'orientation des cernes de croissance, et la dureté.
