Standards:

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

Applications:

Rubber Manufacturing: Quality control for tires, seals, and industrial rubber components.

R&D Laboratories: Material optimization for enhanced resilience and durability.

Third-Party Testing: Certification support for ISO, JIS, and GB/T standards.

Product Information:

The Rubber Resilience Tester is an instrument used to determine the resilience of vulcanized rubber. It works by subjecting a rubber sample to a free-fall impact from a specified height, causing the impact head to strike the sample, and measuring the rebound height multiple times to directly read the rubber's resilience (%).

Technical Parameters

Operation Method

Operation Method (Based on Product Structure and Testing Mechanism)

Place the rubber sample in the test position according to relevant standards, ensuring sample stability.

Check that the impact head assembly is securely installed and confirm that the four suspension wires are vertical.

Raise the impact head to the specified height to meet the 100 mm free-fall impact condition.

Release the impact head, allowing it to fall freely and impact the sample.

Record the rebound height from the 4th to the 6th impacts using the testing mechanism.

Read the rebound rate (%) directly from the direct-reading dial; no additional conversion is required.

If multiple tests are required, repeat the above steps to obtain a stable average result.

Maintenance Method

Maintenance Method (Based on Product Design and Maintenance Information)

Regularly inspect the impact head, suspension wires, and column structure to ensure there is no loosening or deformation.

Keep the contact area between the impact head and the sample clean to prevent impurities from affecting the test results.

Regularly inspect the removable base and impact head for easy calibration and condition verification.

Check the indications on the direct-reading dial to ensure accurate readings.

When not in use, store the equipment in a stable, dry environment to extend its lifespan.

FAQs

1. What is the primary application of the Rubber Resilience Tester?

The Rubber Resilience Tester is mainly used to measure the rebound resilience of vulcanized rubber materials under standardized free-fall impact conditions. It is widely applied in rubber manufacturing for quality control of tires, seals, and industrial rubber components. By providing direct-reading resilience rates, the tester helps manufacturers monitor material consistency and performance. In addition, it is used in R&D laboratories for material optimization and durability studies, as well as by third-party testing organizations for certification support according to ISO, JIS, and GB/T standards.

2. Which standards does the Rubber Resilience Tester comply with?

The Rubber Resilience Tester complies with multiple internationally recognized standards for rubber resilience testing. These include ISO 4662:1986 for international testing requirements, JIS K6255 for the Japanese standard, and GB/T 1681 for the Chinese national standard. Compliance with these standards ensures that test results are comparable, reliable, and suitable for global regulatory acceptance in rubber quality control and certification processes.

3. How does the tester ensure accurate and consistent resilience measurement?

The tester uses a precision-engineered impact head with a diameter of 12.50 ± 0.05 mm and a mass of 0.35 ± 0.01 kg to deliver a controlled 100 mm free-fall gravity impact. Four suspension wires maintain vertical alignment during the free-fall process, minimizing experimental error. The free-fall iron rod measures the 4th to 6th rebound heights to calculate average resilience. A direct-reading dial displays resilience values from 0 to 100% with ±0.1% accuracy, eliminating manual calculations and improving repeatability.
