Rebound Testing: Methods, Standards & Material Applications Guide
A portable rebound tester used for on-site material analysisRebound resilience testing measures the elastic recovery of rubber and elastomeric materials by quantifying the percentage of energy returned after impact. This property—directly related to the material’s hysteresis and damping characteristics—is critical for designing seals, vibration mounts, shoe soles, tyres, and impact-absorbing components. High rebound indicates low energy loss (low hysteresis), while low rebound indicates high damping. For manufacturers seeking rebound testing at a USA-based ASTM testing lab, Infinita Lab provides comprehensive rubber and elastomer testing through its accredited network of over 2,000 partner labs.
How Rebound Testing Works
A standardised pendulum or plunger is released from a fixed height and impacts a rubber specimen. The rebound height is measured and expressed as a percentage of the drop height. A higher rebound percentage indicates greater elastic energy return. The test is rapid, non-destructive, and sensitive to compound formulation, temperature, and cure state.
Testing Standards
ASTM D2632 – Rebound Resilience by Vertical Rebound
ASTM D2632 uses a plunger dropped from a fixed height onto a flat rubber specimen to measure rebound height. It is the most common rebound resilience test for rubber compounds in the Americas.
ASTM D1054 – Pendulum Rebound of Rubber
ASTM D1054 uses a pendulum (Bashore resilience) that swings against a rubber specimen to measure the rebound angle. It provides equivalent information but uses a different impact geometry.
ISO 4662 – Rebound Resilience
ISO 4662 defines the Lupke pendulum method, the international standard equivalent used for rubber resilience characterisation in the automotive and industrial rubber sectors.
Applications of Rebound Data
Rebound resilience data support tyre compound development (energy efficiency versus grip), vibration-isolation mount design, athletic footwear midsole performance, seal-and-gasket energy absorption, ball-bounce characteristics, and rubber compound quality control for formulation consistency.

Frequently Asked Questions (FAQs)
What does rebound testing measure? Rebound testing measures the percentage of impact energy returned by a rubber specimen after a standardized drop or pendulum impact. It characterizes elastic recovery and hysteresis (energy loss) properties.
What ASTM standards cover rebound testing? ASTM D2632 (vertical rebound resilience), ASTM D1054 (Bashore pendulum rebound), and ISO 4662 (Lupke pendulum) are the primary rebound resilience testing standards for rubber and elastomers.
What is the difference between high and low rebound rubber? High rebound rubber returns more energy (low hysteresis)—preferred for energy efficiency (tires, balls). Low rebound rubber absorbs more energy (high hysteresis)—preferred for vibration damping and shock absorption.
How does temperature affect rebound resilience? Rebound resilience increases with temperature as rubber becomes more elastic. At low temperatures approaching the glass transition, rebound drops dramatically as the material becomes rigid and glassy.
How is rebound related to tire rolling resistance? Higher rebound resilience (lower hysteresis) correlates with lower tire rolling resistance and better fuel efficiency. Tire compound development balances rebound (rolling resistance) against grip (wet traction requires some hysteresis).
