Rebound Testing

ASTM D7121


This test method measures the percentage resilience of a rubber compound. Rebound resilience is determined by a pendulum hammer impacting a test specimen. Upon impact, the hammer imparts energy – a portion of that energy is then returned by the specimen to the pendulum and can be measured by the extent to which the pendulum rebounds again.

Test Details

This test method can be used on the following material types:

  • Thermoset rubbers
  • Thermoplastic elastomers
  • Some polyester, polyether foam and plastic foam materials

Common Uses
