Timber structures. Testing of joints made with mechanical fasteners. Requirements for timber density
91.080.20 - Timber structures
EN ISO 8970
Reemplaza a: BS EN ISO 8970:2010
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
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.
