Objective

• This machine is used to test the rebound or resilience property of rubber. It’s determining the impact resilience of solid rubber from measurement of the vertical rebound of a dropped mass.

Operating Mechanism

• Firstly, you need to level the machine and then raise the plunger at given height above the specimen. 

• Now let the plunger to slide freely on its guide rod and then record the average resilience height for the 4th, 5th & 6th impacts.
