ASTM D5961 TESTING FIXTURE – PROCEDURE B

FASTENER BEARING SPECIMEN SUPPORT

ASTM D5961 Testing Fixture

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.

ASTM D5961 TESTING FIXTURE – DRAWING

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