The shear test shall be made by means of a suit- able fixture which meets the following requirements. The clevis pin shall be placed in
31、a hole that passes through a shear block and a plunger within the block. The maximum clearance between the shearing planes of the block and the plunger shall be Q.125 mm (millimeters). The block and the plunger shall be constructed so that the shear planes are normal to the longitudinal axis of the
