ABSTRACT:
The ultimate tensile strength of a test sample is tested in a high speed testing machine having a frame (2), a force measuring device (9A), and a load application mechanism (3, 4) for applying a loading stroke to the test sample after a loading piston has passed through a lead stroke to attain the required testing velocity. A force locking, frictionally effective clamping mechanism clamps the test sample for coupling to the machine frame (2) and/or to the load application mechanism (3) when the loading piston has reached the testing velocity.
