Ross Flex Tester

• 

The ROSS zigzag resistance tester installed the sole strip test piece on the ROSS zigzag test machine, so that the cut is directly above the center of the rotating shaft of the ROSS zigzag test machine, and drove the test piece to perform free 90-degree zigzag on the shaft through the ROSS zigzag test machine. After a certain number of tests, the length of the test piece incision is measured. The zigzag resistance of the test piece was evaluated by the size of the notch growth rate.

Reference standard:

GB/T2099-2007. ASTM-D1052. ISO-5423. SATRA TM60. HB-T2411HG/ T2411 and other standards

Product Advantages:

Measures Key Durability: Quantifies the resistance of sole materials to flex cracking and notch growth, a vital indicator of footwear lifespan.

Standard Compliant (ROSS Method): Designed to meet numerous relevant international and national standards (ASTM D1052. SATRA TM60. etc.) specifically for the ROSS flex test.

Quantitative Result: Provides objective data based on the measured growth rate of the pre-cut notch.

Multiple Testing Stations: Allows simultaneous testing of multiple test pieces (12), significantly increasing testing efficiency.

Controllable Test Parameters: Enables precise setting and control of the bending angle (90$pm$2º) and flexing speed (0-100 r/min).

Automatic Stop Function: Can be set to stop automatically after a specified number of test cycles.

Suitable for Sole Materials: Specifically designed for evaluating the flex fatigue characteristics of sole strips.
