The bearing strength of a 1.5†wide test specimen assembly containing one or two ¼†diameter fasteners is to be determined.
The test sample for procedure B is composed of two identical plates secured together using one or two fixing elements of the central line, with a doubler on each end to minimize bending due to eccentricity of the applied force.

This support device can be used both with tensile or compressive load, to stabilize the unit and further reduce bending effects.
