Application

The tester is applicable to a variety of medical and laboratory products, including:

(1) Collection tubes and blood sampling needles – assessing rubber sleeve rebound force to ensure secure sealing and consistent operation.

(2) Pre-filled syringes – verifying the compression and resilience of protective rubber stoppers.

(3) Catheter and infusion system components – evaluating the elasticity and durability of rubber components.

(4) Quality control in production – ensuring each batch meets predefined resilience specifications.

(5) Research and development – optimizing rubber formulations for medical applications.

Standards

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

Test Procedures

(1) Insert the needle at the butt end into the die hole of the clamping fixture, 2 mm above the surface.

(2) Start the test device to compress the rubber sleeve.

(3) Measure the rubber sleeve resilience at distances of 5 mm and 15 mm between the needle tube and the needle base.

(4) The instrument displays and records the rebound force. Each test can print 8. 10. or 13 data points, including average and deviation.

(5) Confirm that the measured resilience falls within the standard range of 0.5 N ≤ resilience ≤ 1.5 N.
