The test speed shall not exceed 60 times/min. The inspection die shall produce a semicircular slot hole, whose diameter is the nominal size of the overhead. The jaw should have a fillet of r=0.5mm

Eyes should be round as far as possible The cross section of the two legs of the cotter pin should be circular, but it is allowed to have a fillet with radius r=(0.05~0.01) dmax at the junction of the plane of the two legs of the cotter pin and the circumference (d - diameter of the cotter pin)

The clearance between two cotter pins and the displacement of two pins shall not be greater than the difference between the nominal size of the cotter pin and dmax.
