An introduction to impact resilience of solid rubber measured from the vertical rebound of a dropped mass.
Watch the explainer
What the result means
Resilience depends on dynamic modulus and internal friction. Temperature, plunger penetration and instrument type affect comparison. Keep the instrument and test conditions with the reported value.
Scope and limits
The method does not cover cellular rubber or coated fabrics. ASTM says results may not directly relate to end-use performance. A higher rebound value alone is not a service-life promise. This is buyer education, not a laboratory procedure.
