Digital Impact Testing Machine - Mech.CS.DIT30


The pendulum impact tester model Mech.CS.-IT30 is designed for conducting izod, Charpy test. The test methods confirm to BS : 131 : part 4-1972 (amended 15 Aug. 1993)BSEN : 10045-2 : 1993 & ASTM : E-23-94a.
The Pendulum is mounted on antifriction bearings. It has two starting positions, the upper one for Charpy & the lower one for izod testing. On release, the pendulum swings down to brake the specimen and the energy absorbed in doing so is measured as the difference between the height of drop before rupture and the height of rise after rupture of the test specimen and is read from the maximum pointer position on the dial scale. (It is read on Digital Panel in case of digital models)

Controls of Pendulum:

The Pendulum supports 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 & Supports:

There are two strikers and one combined support available for lifting in to the pendulum and 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 it's position.

Charpy Test

The Charpy test piece rests on alloy support anvils, fitted on the base of the machine rigidly held in position by Allen screws. End stopper is provided for quickly and accurately locating the test piece centrally between the supports.

Izod Test

The Izod test is clamped vertically in Izod support 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 and the Allen screw enable clamping of the test piece in correct height with the help of Izod setting gauge supplied.
