In this post, we will show you how to set up MTESTQuattro to set specimen geometry for o-ring specimens.  O-ring testing can be accomplished with an eXpert 7600 single column testing system and a set of specialized o-ring tensile fixtures.

With MTESTQuattro running, navigate to the specimen tab.

Selecting Geometry

  • For Flat O-Rings:
    • In MTESTQuattro, go to the Specimen tab of the active test procedure.
    • Select Flat O-Ring as geometry type (Figure 1).

  • For Round O-Rings:
    • In MTESTQuattro, go to the Specimen tab of the active test procedure.
    • Select Round O-Ring as geometry type (Figure 1).

Selecting Analysis

  • In MTESTQuattro, go to the Analysis tab of the active test procedure.
  • Select User as the analysis suite.
  • Highlight O-Ring and click Select.
  • O-Ring should now be listed in the selected analysis section.

Running a Test

  • Measure specimen
  • Update specimen dimensions in MTESTQuattro if necessary (Figure 4).
  • Perform test.
  • After the test has completed, the Tensile Strength (psi) and Elongation (%) will be calculated.
