Digital Ball Rebound Resilience Tester

Digital Vertical Rebound Resilience Tester - GenReboundBall Rebound Tester is a device designed to test resilience of materials such as foam, polyurethane and other similar materials. The unit comes certified in accordance with ASTM D3574 industry standards. The test consists of a 16mm magnetic ball dropping freely onto a sample from a specified height of 500mm. The electronic console unit that comes standard with this instrument will show the measured value and calculate the proportion of the average value in %. After the test completion, a sensor placed close to the holder ensures that the ball is returns to the home position.

 

Digital Ball Rebound Resilience Tester Features

  • Plug-n-Play System
  • Extremely Easy to Learn to Operate
  • Short Measuring Cycle
  • USB Port
  • Test cycle, measured values, median value in %, status and operating instructions output to 4-line LCD
  • No Calibration Requirements

Analogue Ball Rebound Resilience Tester

Analogue Vertical Rebound Resilience Tester - GenRebound

GenRebound tests the resilience of rubber compounds. The machine must be adjusted in a horizontal position and the plunger raised at a specific height. The plunger is then released onto the specimen for a given number of impacts. The measurements are based on the 4th, 5th, and 6th impacts. The average of the three (3) measurements is then calculated for the test result. The machine is highly useful in production of compounds designed to absorb vibration or shock according to the ASTM standards.

The Operating Process Of Analogue Ball Rebound Resilience Tester

The resiliometer is based on the vertical free-fall hammer method to test the elasticity of rubber materials. First adjust the tester level the elevation degree of drop hammer. Place the test films 14mm from the edge of the specimen. The first three tests are not used for record. Use only the average reading of the fourth, fifth and sixth tests.

This test apparatus was created using ASTM-D2632, ISO-10012, and other standard papers, and it is primarily used to measure the rebound height of hard rubber materials. It cannot be used to measure the rebound height of soft rubber or glued leather.

Installation:

  • Operating environment conditions: The required temperature is (23 ± 2) ° C, and the humidity is (65 ± 5) RH%
  • The instrument should be placed on a flat platform of 25cm x 15cm or more.

The ISO standard known as ISO 10012:2003, Measurement management systems - Requirements for measurement processes and measuring equipment, lays out general requirements and offers instructions for the management of measurement processes and metrological confirmation of measuring equipment used to support and demonstrate compliance with metrological requirements. In order to ensure that metrological standards are met, it describes the quality management requirements of a measurement management system that can be utilized by an organization that performs measurements as part of its overall management system.

It is not intended for ISO 10012:2003 to be used as a prerequisite for proving compliance with ISO 9001, ISO 14001, or any other standard. The use of ISO 10012:2003 as input for fulfilling the needs of measurement management systems in certification operations is open to interested parties.

There are further standards and guidelines for specific factors influencing measurement outcomes, such as the specifics of testing procedures, staff competency, and interlaboratory comparisons.

The requirements of ISO/IEC 17025 are not to be replaced or supplemented by ISO 10012:2003.

This test instrument was created using ASTM-D2632, ISO-10012, and other standard documents, and it is primarily used to measure the rebound height of hard rubber materials. It cannot be used to measure the rebound height of soft rubber or glued leather. In units are the test results. Although the test method can be used to identify and research materials, it cannot directly assess final performance.

Adaptive Vertical Rebound Using the free fall weight method, the tester evaluates the rubber materials' elasticity. Adjust the instrument's horizontal position first, and only after that elevate the drop weight to the desired height. Make sure the drop point is 14 millimetres from the test piece's edge when you set it down. The average of the fourth, fifth, and sixth rebound heights was recorded; the first three trials were not used.

Rubber compound resiliency is examined via GenRebound. The machine must be positioned horizontally, with the plunger lifted to a predetermined height. The measurements are based on hits four, five, and six. The test result is then determined by taking the average of the three (3) measurements. The equipment is very helpful in producing compounds that meet ASTM criteria for vibration or shock absorption.
