The Bareiss Ball Rebound Tester is widely used by top hybrid mattress manufacturers worldwide to assess the durability of materials like foam and polyurethane. Without the use of a Bareiss Foam Resilience Tester, it would be difficult to provide the highest-quality sleep experience from our mattress. The footwear industry is another sector that depends on our rebound resilience tester. Whether it is for premium sports footwear or ordinary shoes, we are all familiar with the significance of comfort for our feet!

The elasticity of polymeric foam materials can be assessed using the Bareiss Ball Rebound Tester, which measures the height to which a ball rebounds after free falling and impacting a test specimen, ensuring ASTM D3574 rebound and DIN EN ISO 8307 compliance. This foam testing equipment, also known as a rubber rebound tester, features a 2-line liquid crystal display (LCD) indicating the measured and median values in percentage. The height of the rebound is electrically measured using sensors, adhering to the ASTM foam rebound and ISO 8307 ball test standards. The ball is held firmly in place by a magnetic holder until the measurement procedure begins; at this point, it is manually released using the handwheel.

Applications

The Bareiss Ball Rebound Tester is essential for various applications, including:

• Hybrid Mattress Manufacturing: Assessing the durability and resilience of foam and polyurethane materials to ensure the highest quality sleep experience.
• Footwear Industry: To guarantee comfort, we measure the rebound resilience of materials used in premium sports footwear and ordinary shoes.
• Polymer and Foam Testing: Conducting polymer rebound measurement and foam resilience tests in compliance with ASTM D3574 and DIN standards rebound test requirements.
• Quality Control: Ensuring consistent performance and durability of foam products by adhering to DIN EN ISO 8307 compliance standards.
• Material Research and Development: Investigating the resilience properties of new foam and polymer materials to enhance product quality.

By utilizing the Bareiss Ball Rebound Tester, industries can achieve precise and reliable measurements of foam and polymer resilience, ensuring their products meet the highest standards of performance and durability.

Individual measurement with a mode of 0:

1) The electronic gadget is powered off and the encoded switch is rotated to position 0 using a screwdriver.
2) Loosen the clamping screw of the fixing bracket to raise the downpipe until there is a gap between the downpipe and the sample resting on the supporting table.
3) Gently lower the pipe until the bottom is in contact with the sample and securely fasten the clamping screw.
4) Rotate the knurled wheel counterclockwise until it reaches its maximum limit. Then, using a magnet holder, place the ball into the holder plate. Finally, rotate the knurled wheel clockwise until it reaches its maximum limit.
5) Release the ball and allow it to descend into the sample, then extract the ball using a magnetic holder.
6) The recorded value is sent over the interface to the computer.

The measurement is conducted according to the DIN EN ISO 8307 standard using mode 1, which calculates the median value.

1) Norm 3 requires doing three measurements on each of the three samples. From each set of measurements, a median value is computed, and then a median value is generated from the three median values.
2) The electrical gadget is powered off and the encoded switch is rotated to position 1 using a screwdriver.
The median is calculated from three measurements taken from three different samples. After obtaining three median values, the final median value is presented.
4) The recorded value is sent via the interface to the computer.

Measurement using pre-existing data in mode 2 (median value):

1) The electronic gadget is powered off and the encoded switch is rotated to position 2 using a screwdriver.
2) Three measurements are conducted for preconditioning, and the measurements are repeated twice.
3) After obtaining preconditioning values, 3 values are collected from 3 samples each, and the ultimate median value is determined.
4) The computed median value is sent across the interface to the computer.

Measurement according to ASTM D 3574 using mode 3 (average value):

1) The electronic gadget is powered off and the encoded switch is adjusted to position 3 using a screwdriver.
2) Norm 3 requires taking 3 measurements on each of the 3 samples, and then calculating the average value for each set of measurements. Finally, an overall average value is determined from the three average values.
Three readings are taken from three samples, and the resulting average is shown. The ultimate average value is presented after three average values are acquired.
4) The recorded value is sent via the interface to the computer.

Measurement using pre-existing data in mode 4 (mean value):

1) The electronic gadget is powered off and the encoded switch is adjusted to position 4 using a screwdriver.
2) Three measurements are made for preconditioning and the measurements are repeated twice.
3) After obtaining preconditioning values, 3 average values are derived from 3 samples each, and the final average value is determined.
4) The computed mean value is sent across the interface to the computer.
