Timber structures — Testing of punched metal plate fasteners and joints ISO 8969:2011

Publication date:   Oct 21, 2011

Scope

ISO 8969:2011 specifies test methods for determining the strength and stiffness of joints made with punched metal plate fasteners in load-bearing timber structures, as follows:

load-slip characteristics and maximum load resulting from the lateral resistance of the embedded projections, at various angles between the direction of the applied force and

the axis of the plate (load-plate angle, α),
the direction of the grain of the timber (load-grain angle, θ);


the tensile strength of the plate at various angles, α;
the compression strength of the plate at various angles, α (optional test);
the shear strength of the plate at various angles, α.

ISO 8969:2011 is linked to ISO 6891, which gives general test requirements.
In addition, a method for testing the nail root in alternate bending is specified in Annex A.
