1. Test purpose: Test the ability of the sole to resist incision growth after continuous twists and turns, that is, tolerance resistance.
2. Scope of application: It is mainly suitable for various types of tortuous sulfurized rubber sole, and also suitable for other various types of fluxless sole.
3. Test principle: Install the sole strip test piece on the SATRA TM60 Ross Flex Tester, so that its incision falls directly above the rotary axis center of the Ross Flex Resistance Testing Machine. Through the ISO 5423 Sole Bending Tester and turning test, the test piece was pulled to 90 ± 1 degrees on its shaft. After a certain number of tests, the length of the test tester was measured. Evaluate the quality of the test sole resistance performance with its incision growth rate.
4. Test Instrument:
ROSS
Flexing Tester: ROSS Flexing Tester is used to test the
vertical flex resistance of rubber products, sole of shoes, and Foamed material
suce PU、PVC、TPR.
After flexing a certain times, then check the attenuation, damage and cracking
degree to get the flexing resistance of the sample.
