Tinius Olsen’s model IT800 impact tester is an 800 Joule pendulum impact tester used to determine the impact strength of notched bar metal materials. This test relates specifically to the behaviour of metal when subjected to a single application of a force resulting in multi-axial stresses associated with a notch, coupled with the high rate of loading.
The IT800 uniquely features a patented “Active follower” technology in support of fast efficient testing, whereby the moving pendulum is caught immediately the test is complete and quickly returned to its safe holding position ready for the next test. The active follower technology does not use a clutch based motor system and therefore is designed for high throughput of tests in a heavy industrial environment requiring nominal servicing and maintenance.
Additionally fast test throughput is supported by the digital “light curtain” option, this option replaces a conventional door to the enclosed test area permitting the user to quickly insert test specimens in the Charpy holder without the need to physically open and close a door, this is particularly efficient when testing cooled notched specimens. From a safety perspective the light curtain if broken by an operator during a test instantly causes the active follower to arrest and halt the moving pendulum thus ensuring operator safety, in fact breaking the light curtain is easier and faster than hitting an emergency stop button (which is still present).
The Tinius Olsen IT800 metal impact supports tests in accordance with ASTM E23 and ISO 148, these tests can be carried out through the touch screen user interface and or Tinius Olsen’s Horizon impact testing software running on a PC or over a network.
