Abstract
Test samples, especially samples made of ceramic materials, are tested under tension and/or compression loads while simultaneously avoiding the application of a bending moment to the test sample. For this purpose, each end of the test sample is held by a holding element having spherical outer surfaces received in spherical segment recesses of clamping jaws. Each test sample end is held by its holding element in a form-locking force-transmitting manner without a direct contact between the clamping jaws and the test sample. The application of bending moments to the test sample is avoided because the cooperating spherical surfaces permit an adjustment of the testing sample into a vertical position without any canting of the test sample.
