scope:

This International Standard specifies two methods for the selection of wood density for specimens which are to be used in determining by testing the strength and stiffness properties of joints made with mechanical fasteners. The two methods are equally applicable. It is assumed that the wood density is normally distributed with a coefficient of variation of about 0,15. It is emphasized that the density is only one of the properties influencing the strength of a joint. Other relevant properties are, for example, growth ring size and slope of grain.
