Purpose. This test procedure shall be used to determine the compression properties of metal center tubes and contact surfaces of metal parts with bolt through holes.

Definition. The compression properties of metal center tubes and contact surfaces of metal parts with bolt through holes as determined by this test procedure shall be defined as the permanent length change of a part mentioned previously, when subjected to an axial pressure applied at a fixed velocity. The compression properties can be expressed by a force-displacement hysteresis curve.
