2. Twist compression tester - Wikipedia

   en.wikipedia.org/wiki/Twist_compression_tester

   The Twist Compression Tester ("TCT") is a hydraulically operated bench-top apparatus used to evaluate the level of friction and/or wear between two materials under lubricated or non-lubricated conditions. Under controlled conditions, a rotating annular specimen is brought into contact with a non-rotating flat specimen.

3. Leak-down tester - Wikipedia

   en.wikipedia.org/wiki/Leak-down_tester

   Compression tests should normally be done with all spark plugs removed to maximize cranking speed. Cranking compression is a dynamic test of the actual low-speed pumping action, where peak cylinder pressure is measured and stored. A compression tester. Leak-down testing is a static test. Leak-down tests cylinder leakage paths.

4. Container compression test - Wikipedia

   en.wikipedia.org/wiki/Container_compression_test

   Industrial and consumer packages other than boxes can also be subjected to compression testing: drum, pail, bottle, tub [1] etc. Package components are also evaluated for compression resistance. [2] It is usually a laboratory test involving a special machine, a compression tester, to apply controlled compression on a test specimen.

5. Plane strain compression test - Wikipedia

   en.wikipedia.org/wiki/Plane_strain_compression_test

   The advantages of the Watts-Ford test are that it is convenient for testing thin sheets or strips, it is similar to a rolling process (in manufacturing analyses), frictional effects may be minimized, there is no 'barrelling' as would occur in a cylindrical compression test, and the plane strain deformation eases the analysis. Stress-strain curve

6. Split-Hopkinson pressure bar - Wikipedia

   en.wikipedia.org/wiki/Split-Hopkinson_pressure_bar

   For compression testing, two symmetrical bars are situated in series, with the sample in between. The incident bar is struck by a striker bar during testing. The striker bar is fired from a gas gun. The transmitted bar collides with a momentum trap (typically a block of soft metal). Strain gauges are mounted on both the incident and transmitted ...

7. Automatic test equipment - Wikipedia

   en.wikipedia.org/wiki/Automatic_test_equipment

   Automatic test equipment diagnostics is the part of an ATE test that determines the faulty components. ATE tests perform two basic functions. The first is to test whether or not the Device Under Test is working correctly. The second is when the DUT is not working correctly, to diagnose the reason.
