Impact testing machines evaluate an object’s capacity to withstand high-rate loading and it is commonly used to determine the service life of a part or material. Impact resistance can be among the most challenging qualities to measure. … There are two standard kinds of impact test: Charpy and IZOD.

Arun is one of the leading manufacturer and exporter of Impact Testing Machines. We design and build different models of impact testing machines with utmost precision, with the help of state of the art technology. Impact testing machine is used to test the resistance of metal & alloys to external impacts.
The Pendulum Impact Tester Model IT 30 is designed for conduction Izod & Charpy Test. The test methods confirm to BS:131:PART 4-1972 (Amended 15 Aug. 1993) & BSEN: 10045 – 2 : 1993.
The Pendulum is mounted on antifriction bearings. It has two starting positions, the upper one for Charpy and the lower one for Izod testing. On release, the Pendulum swing down to break the specimen and the energy absorbed in doing so is measured as the difference between the height of drop before rupture & height of raise after repture of the test specimenn and is read from the maximum pointer on the dail scale.
The Charpy test piece rests on alloy steel supports anvils fitted on the base of the machine rigidly held in position by alien screws. End stopper is provided for quickly & accurately locating the test piece centrally between the supports.
The Izod test piece is clamped vertically in Izod support anvils, fitted on the base of the machine. The support is provided with a machined vertical groove to suit the test piece size. The front clamp piece & alien screw enable clamping of the test piece in correct height with the help of Izod setting gauge supplied.
Controls of Pendulum
The Pendulum supported in the starting positions is by a self resetting latch. The release mechanism is operated by lever. The Pendulum release latch is operated only when this lever is operated.
Strikers & Supporters
There are strikers & one combined support available for fitting into the Pendulum & on to the base of the machine for Izod, Charpy test. Changing from one striker to another is achieved simply by fixing the new striker into its position.
