Rebound Resilience Testers

Zwick 5109 rebound resilience tester

The Zwick 5109 rebound resilience tester is available in two basic versions, for the following applications and standards:

  • for tests on elastomers and rubber to DIN 53512 (elastomers and rubber); ISO 4662 rubber); BS 903 Part A8, Method B (rubber); ASTM D 1054, Method B (Schob)
  • for tests on foam materials to DIN 13014 (polyether foam hospital mattresses).

Overview of Zwick 5109 rebound resilience tester

Advantages and features

  • Device features/data
  • Resolution 0.06 degrees
  • The testing system is extremely low-maintenance: The only actuator during fully automatic sequences is the gear motor.
  • The pendulum encoder.
  • The free from wear mechanics.
  • - The keyboard is dust proof.
  • The standby mode and LCD display turn this device into a low energy device.
  • Operation
  • Operation is menu driven.
  • The pendulum height is easily adjustable via an eccentric with the help of a settings program.
  • Two test programs for determination of the duration of swing as well as the friction are integrated in the device.
  • The required standard is selectable and the sequence can be configured.
  • Several languages can be set (English, German, and a third one open for assignment)
  • You can connect to a PC and to Zwick's testXpert testing software.
  • The testing software offers various possibilities for data transfer (from device to PC) as well as for evaluation, further processing, documentation, and saving test results.
  • Rapid error analysis is possible through an integrated routine.

Ball rebound tester

Zwick 3107 ball rebound tester

The microcomputer-controlled Zwick 3107 rebound tester is used for determining the rebound resilience of foams to EN ISO 8307 and ASTM D 3574, plus latex foam rubber to JIS K 6382. A steel ball with a diameter of 16 mm is released precisely via a magnet and falls from a specified height on to the specimen. The instrument electronics determine the rebound height of the ball by means of a triple light-barrier and calculate the rebound resilience from it.
