ASTM D7121 is the test method for the rebound resilience of rubber and similar elastomeric materials. To match this to your program, talk with our team.
What ASTM D7121 Covers
It measures the fraction of impact energy a rubber returns on rebound, an indicator of elasticity and hysteresis used in material comparison.
How the Test Is Run
A pendulum or indenter impacts the rubber specimen, and the rebound relative to the impact gives the resilience as a percentage of returned energy.
Why It Matters
Rebound resilience characterizes elastic and damping behaviour; a calibrated rebound apparatus and controlled conditioning are used.
