Description

Ross Flex Tester is designed to determine the resistance of vulcanized or synthetic elastomers to cut growth. The system does so under continuously bend flexing in 90°. This digital system has a memory function and is suitable for PU, PVC and TPR foams. It is particularly used for shoe soles because it is capable of testing virtually any flexible sheet-like material. After continuous bending, the damage and cracking degree is examined. The machine clamps the end of the test specimen to the holder arm while the pierced end is placed between two rollers that must permit a free bending movement of the test specimen during the test. During each of the test cycles, the pierced area of the test specimen is bent freely over a 10-mm(0.4 in.) diameter rod through a 90° angle. According to the industry standard, the Ross Flex tester operates at 1.7 ± 0.08 Hz (100 ± 5cpm). After a specified number of tests, the operator will measure the length of the notch of the test piece, and evaluate the zigzag resistance of the test sole relative to the notch growth rate.
