Sponge Repetitious Compression Tester
This tester is used to test the permanent rate of deformation for the samples like sponges. Before testing, measure its original thickness as t0. Compress the sample to 50% of its original thickness at the speed of 60RPM (or as stipulated) for 80,000 cycles. Then, discharge the sample and let it calm down aside for at least 30 minutes. Measure its final thickness t1 and calculate its permanent rate of deformation as the following formula:

This tester can test two samples at the same time in order to save time.
