The EN ISO 4651 Foam Rebound Tester is designed for determining the rebound performance of flexible polyurethane foam. This instrument measures the percentage ratio between the maximum ball height and rebound height when a ball of specified mass and diameter falls freely from a predetermined height onto foam samples. Featuring microprocessor control, LCD Chinese display, and built-in printing capabilities, this machine offers safe operation, reliable performance, and precise measurements.
Designed and manufactured in accordance with GB/T6670-97, meeting American standard ASTM D3574 and ISO 8307 requirements.
