Impact Testing Machine Manufacturer,Supplier and Exporter in India

Product Code : EL-CL-8858
Jlab Export is a leading Impact Testing Machine Manufacturer,and suppliers in India

This pendulum machine runs both Charpy and Izod impact tests on notched specimens. The pendulum swings on antifriction bearings from a raised starting position and breaks the specimen at the bottom of its arc. The energy absorbed in the break is read from a maximum pointer on the dial scale.

Impact Test Practicals in the Materials Lab

In a strength of materials lab, students break notched bars by both methods and compare the energy each one absorbs. For Charpy, the bar lies across the support and the striker hits the middle, on the face opposite the notch. For Izod, the bar is clamped upright as a cantilever and struck near its free end, on the notched side.

Before the test, they check each bar and its notch with a Vernier Caliper. Afterwards they study the broken faces. A bright, granular face points to brittle fracture, while a dull, fibrous face with bent edges shows ductile tearing. Teachers can set the result beside a tensile test of the same steel on the Motorized Compression/Tension Machine.

Frequently Asked Questions

What is the difference between the Charpy and Izod tests?
In Charpy, the specimen is supported at both ends and struck in the middle. In Izod, it is held at one end and struck near the other. On this machine, Charpy uses the upper starting position and its own striker, and Izod the lower position and the second striker.

How is the absorbed energy read?
The pendulum loses height in breaking the specimen, so it rises less on the far side than it fell. The maximum pointer stays at the highest point of that swing, and the dial reads the energy from the difference between the drop and the rise.

Should I take a free swing before testing?
Yes. Release the pendulum with no specimen in place from the same starting position. The small reading it gives is the loss to bearing friction and air, which you note and allow for in the results. Reset the pointer before each swing.

How do I change over from Charpy to Izod?
Fix the other striker into its position on the pendulum, then mount the specimen on the combined support for the new test. Raise the pendulum to the matching starting position, where the self-resetting latch holds it until you work the release lever.

Can this machine test road aggregate?
No. It breaks notched bars with a swinging pendulum. The aggregate impact value comes from a falling-hammer test on aggregate in a cup, done with the Aggregate Impact Tester.
