Description
- This tester is used to repeatedly test compression residual strain of polyurethane foam and latex foam soft material according to the constant displacement method.
- Placing the test specimen between the two parallel plates and continuously repeating the compression to the test specimen 80,000 times at a compressing power so that the test specimen’s thickness becomes 50 % of the initial size.
- 30 minutes after the test specimen has been repeatedly compressed, the decreasing rate of the test specimen’s thickness is to be measured.
