ASTM D4255 Test Fixture | GD4255-962


Model #
GD4255F1-962 test fixture meets ASTM D4255 FIG1 requirements. Procedure A consists of a flat panel with holes along opposing edges that is clamped by through bolts, between two pairs of parallel steel loading rails. When loaded in tension, this fixture introduces shear forces in the specimen that produce failures across the panel. Two-rail shear fixtures can also be compression loaded. The load may be applied to failure. The rails are attached to the test machine through test machine adapters. A load plate aligns the rails with each other. Specimen flatness is essential to minimize the likelihood of buckling.
