Using an Impact Tester for Testing

The notch impact test, which is a materials testing method, can be used to determine the ductility of materials in a relatively quick and straightforward way. The new HIT450P pendulum impact tester launched by ZwickRoell for conducting tests on metals has been ideally adapted for the testing process.

Fundamentals of Notch Impact Tests

While performing notch impact tests, a material specimen is tested under impact loading in the form of an elongated building block - single-sided, notched and typically tempered. The unnotched rear side of the specimen is struck and broken by a pendulum hammer. During the deformation process, the specimen absorbs part of the transferred kinetic energy, thereby preventing the pendulum hammer from swinging up as far on the opposite side. Then, the energy loss is used to ascertain the absorbed energy for a specific material at a specific temperature.

Using HIT450P for Notch Impact Tests

More than 160 years of expertise and application knowledge were applied in combination to develop the new HIT450P. A range of options enables the basic instrument to be adapted to a broad array of applications. Accurate and reliable testing is guaranteed by the ergonomic design and the logical user interface in the testXpert III testing software.

Consequently, input options available to the user are considerably decreased. Since users see only what is important to them, they can concentrate on the task at hand. The pendulum impact tester’s design has been further improved: the central arrangement of the user elements reduces test cycle times as it is possible to easily remove the specimen remains from defined locations after impact. It goes without saying that the testing instrument complies with the strict safety requirements of ISO 13849-1 and fulfills the high quality expectations of the customers from ZwickRoell.
