Rebound Resilience Elasticity Tester

The Rebound Resilience Elasticity Tester is a digital instrument. It determines the resilience elasticity of elastomers, soft elastic foams and similar during shock loading calculation of median value. The median value is on the display and sent to the PC afterwards. A test function allows the control of the prescribed double swinging.

The resilience elasticity is the ratio of the regained energy in relation to the applied energy. This ratio of energy corresponds with the quotient of the height of the resilience and the height of the drop of the pendulum.

It is used for elastomeres within a hardness range from 30 to 85 Shore A or IRHD N. And integrated friction control of the bearing. Thus, Rebound Resilience Elasticity Tester meets necessary standards.

Rebound Resilience Elasticity Test

There are two methods for determining the rebound resilience of rubber the hardness of which lies between 30 IRHD and 85 IRHD. They are the pendulum method and the tripsometer method.With the pendulum method, a mass with a spherical end impacts a flat test piece, firmly held but free to bulge. The kinetic energy of the impacting mass is measured immediately before and after impact.

With the tripsometer method, a flat test piece is impacted by a hemisphere mounted on the periphery of a disc which is supported on an axle and caused to rotate by an off-axis mass. The kinetic energy of the impacting mass is measured immediately before and after impact.
