Ball clearance is necessary for high-speed shear testing due to the high speeds
involved and the need to allow acceleration to the test point and deceleration after
test. The aim of this ball clearance is to remove all the balls on the sample except
the balls on one edge.

7.6.1 Shear tool quality
The tip of the shear tool should be free of chips and damage. It should be inspected at
regular intervals and replaced if it becomes damaged.
7.6.2 Ceramic shear tool removal
The ceramic shear tool fitted to the load cell can be removed easily however if it is
removed a recalibration will be required.
