Applications:

The Roller Shear Fatigue Tester is intended to provide a means for the evaluation of foam samples utilizing the shear roller.

This allows for comparison of the performance of different types of foams under the same conditions of use.

A foam sample is placed under a traversing 45kg roller for 20,000 cycles. The height loss, firmness loss and degree of stretch is measured after the 20,000 cycles is completed.This test is used as a comparative evaluation against previously tested foam specifications.

Standards:
