This International Standard specifies test methods for determining the strength and stiffness of joints made with punched metal plate fasteners in load-bearing timber structures, as follows: a) 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); b) the tensile strength of the plate at various angles, α; c) the compression strength of the plate at various angles, α (optional test); d) the shear strength of the plate at various angles, α. This International Standard 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.
