MTESTQuattro Sample Test: O-Ring Analysis

Home / Testing Guides / MTESTQuattro Sample Test: O-Ring Analysis

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 2).

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.
