Rubber Resilience Tester | Rubber Rebound Resilience Tester

Standard

Complies withISO 4662:1986(international),JIS K6255(Japan), andGB/T 1681(China) standards for standardized resilience testing of vulcanized rubber, ensuring global regulatory alignment.

Product Advantages

Precision Engineering: High-precision impact head and dial system for accurate resilience rate measurements (±0.1% repeatability).

Robust Design: Heavy-duty base and detachable components simplify calibration and maintenance, enhancing longevity.

User-Friendly Operation: Direct-reading dial eliminates manual calculations, streamlining testing workflows.

Versatile Compliance: Meets multiple international standards, ideal for global quality control in rubber manufacturing.

Consistent Performance: 4 suspension wires ensure vertical alignment during free-fall impact, minimizing experimental error.

Product Features

Impact Head Assembly:

Specifications: 12.50 ± 0.05 mm diameter, 356 mm length, 0.35 ± 0.01 kg mass.

Energy Delivery: 100 mm free-fall gravity impact with hemispherical striking end.

Testing Mechanism:

Free-fall iron rod triggers 4th-6th rebound height measurement for average resilience calculation.

Detachable base and impact head for easy equipment adjustment and inspection.

Dial System:

Direct-reading scale displays resilience rate (%), eliminating conversion tables for most applications.

Optional conversion formula provided for horizontally scaled intervals.

Structural Integrity: Rigid column and base support high-force impacts, ensuring stability during testing.
