This video shows a compression test on a rubber door seal to obtain the load vs. deflection curve and to determine the load at various displacements.  For example, our customer wanted to know the load at 5, 15, and 30% compression of the original height.  The zero point on the X (displacement) axis was set for the design height.  Load on the chart before or after the zero point would indicate manufacturing tolerance- either the seal was produced too large or too small.

 

 

 

 

This test was performed on an ADMET eXpert 7601 universal testing machine.
