- IITRI in the USA developed a similar tool with column guides, which nowadays replaces the old Celanese compression tool in ASTM. This test fixture—like its predecessor model—uses a wedge clamping principle.
- The wedge jaws are first aligned to the specimen outside the compression fixture and then placed into the compression fixture.
- The gripping pressure is generated with a wedge action during the test via the axial force, resulting in wedge movements that could lead to bending in the specimen.
