The machine is designed and manufactured in accordance with GB/T6670-2008, in accordance with ASTM D3574 and IS08307 test standards and in accordance with the test method of SESN3296, which is used for testing the falling ball resilience of soft polyurethane foam. The instrument through the given diameter and quality of the steel ball in the specified height of the free fall on the foam sample, calculate the large height of the ball rebound and steel ball fall height ratio of the percentage of the rebound rate, the rebound rate represents the resilience of the foam. The machine adopts microprocessor control, LCD Chinese display, and can print test data. This machine has the characteristics of reliable use and high measuring accuracy.
