Notched-bar impact testing

With the notched-bar impact testing we determine the toughness of a metallic or polymeric material under various temperature conditions. Qualitech has one of the few pendulum impact testers in Switzerland that is certified according to NIST (National Institute of Standards and Technology), with which we carry out tests according to ASTM.

Determining toughness

To determine the material toughness, the notched-bar impact testing is used, for which standardized specimens are manufactured by Qualitech and pierced with a pendulum hammer in the cooled or heated state. The notched bar impact test specimen is completely broken or plastically deformed. From the vibration height
after the blow, the work consumed results in Joule. The toughness value is given in J/cm2 on consumed work per area.
