FAQs of Foam Ball Rebound Test Machine:
Q: How does the Foam Ball Rebound Test Machine evaluate foam resilience?
A: The machine measures rebound elasticity by dropping a standard steel ball of 16g onto a foam specimen at a controlled height, then records the rebound percentage digitally. This process aligns with ISO 8307 and ASTM D3574 test methods.
Q: What is the process for adjusting the drop height during testing?
A: You can manually set the drop height using the integrated digital scale, allowing precise selection between 60 and 500 mm to meet specific test requirements. The adjustment is straightforward and displayed clearly on the LED panel.
Q: When should I use the emergency stop and what safety features are present?
A: If any unsafe situation arises during operation, press the emergency stop button to immediately halt all machine functions. An integral shield is also provided to protect the operator from moving parts and ball impact.
Q: Where can I export or share test data from the machine?
A: Test results can be conveniently exported via USB or RS232 interfaces. These output options allow you to transfer data to computers or lab systems for further analysis or documentation.
Q: What are the advantages of digital microcomputer control in this foam tester?
A: Digital microcomputer control allows for accurate parameter setting, automatic calculation, faster response times, and reliable data storage, improving overall test consistency and reducing user error.
Q: How is the machine suited for lab and quality control use?
A: The bench-top design, quick data output, and accuracy of 0.1% make it ideal for laboratories and quality control departments that require repeatable, standardized testing of polyurethane foam resilience.
