Rubber 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

1. Precision Engineering: High-precision impact head and dial system for accurate resilience rate measurements (±0.1% repeatability).
2. Robust Design: Heavy-duty base and detachable components simplify calibration and maintenance, enhancing longevity.
3. User-Friendly Operation: Direct-reading dial eliminates manual calculations, streamlining testing workflows.
4. Versatile Compliance: Meets multiple international standards, ideal for global quality control in rubber manufacturing.
5. 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.
