HIT Pendelum Impact Testers for tests on plastics specimen from 5 J to 50 J.
Impact testing is used to determine material behavior at higher deformation speeds. Classical pendulum impact testers determine the impact energy absorbed by a standardized specimen up to break by measuring the height of rise of the pendulum hammer after impact.
Several test methods are commonly employed:
♦ Charpy (ISO 179-1, ASTM D 6110)
♦ Izod (ISO 180, ASTM D 256, ASTM D 4508) plus 'unnotched cantilever beam impact' (ASTM D 4812)
♦ Impact tensile tests (ISO 8256 und ASTM D 1822)
♦ Dynstat impact bending test (DIN 53435)
► Pendulum Impact Testers for Plastics Testing - Accurate, Reliable and Operator-Friendly ◄
Together with tensile and flexure tests, Charpy impact tests are the most frequently performed mechanical tests in the polymer industry. ZwickRoell’s HIT range of pendulum impact testers offer a solution that combines high precision with cost effectiveness.
► Advantages ◄
♦ HIT pendulum impact testers automatically identify the pendulum in use, ensuring that measured values are always determined in the correct range and in accordance with the standard in use.
♦ A world first is the use of carbon double rods for the pendulum. This provides a high level of stiffness in the impact direction and a strong concentration of masses at the point of impact.
♦ Each pendulum is equipped with a quick-change device. Pendulums can be changed quickly and without the need for tools.
♦ The optional pendulum disc brake is virtually wear-free.
♦ Operator convenience is a prominent feature of the HIT pendulum impact testing systems. Easy-to-reach controls, on the same level wherever possible, help avoid user fatigue.
♦ The electronics contain a high-resolution digital encoder for accurate measurement of the impact angle. An RS232 interface is available for connection to laboratory data-management systems. A PC can be connected via a USB plug-and-play interface.
