The Rubber Sleeve Rebound Tester is designed to comply with the following standards:

(1) YY/T 1618-2018: Collection Needle Rubber Sleeve Resilience Test (China)

(2) DIN 53 512: Testing of Rubber – Rebound Resilience (Germany)

(3) ISO 4662: Rubber, Vulcanized or Thermoplastic – Determination of Rebound Resilience

(4) ASTM D7121: Standard Test Method for Rubber Compression Set

Features

(1) Accurate measurement of rubber sleeve resilience at multiple distances.

(2) Adjustable test speed and pressure for various sample requirements.

(3) Real-time display of test force and calculated results.

(4) Onboard printing for test reports, including average values and deviation.

(5) Supports testing of needles and collection tubes with minimal setup.

(6) Compact design suitable for laboratory and production environments.
