The Ross Flex Tester evaluates the zigzag resistance and flex fatigue performance of sole materials. Pre-cut sole test pieces are mounted on the tester and subjected to repeated 90° zigzag bending. The notch growth rate is measured after testing to quantify the flex cracking resistance of the material, providing an objective assessment of sole durability.
Applications
(1) Sole strips of sports shoes: EVA, PU, rubber, or TPR soles used in athletic footwear.
(2) Casual shoe soles: Leather, synthetic, or composite materials.
(3) Work shoe soles: Polyurethane, rubber, or thermoplastic soles.
(4) Footwear R&D: Evaluating new sole materials or surface treatments for flex durability.
(5) Quality control in production: Checking consistency and durability of sole strips before assembly.
(6) Laboratory testing: Comparing notch growth and flex cracking among different materials.
Standards
(1) GB/T 2099-2007 — Footwear Test Methods
(2) ASTM D1052 — Standard Test Method for Flexing Endurance of Sole Materials
(3) ISO 5423 — Rubber and Plastics — Determination of Flex Cracking
(4) SATRA TM60 — Ross Flex Test
(5) HG/T 2411 / HB-T2411 — Footwear Sole Flexing Test Methods
(6) EN ISO 20344 — Footwear — Test Methods
Features
(1) Measures sole material flex fatigue and notch growth, key indicators of durability.
(2) Supports simultaneous testing of 12 sole test pieces for high throughput.
(3) Provides objective data based on notch growth rate.
(4) Adjustable bending angle (90 ± 2°) and flexing speed (0–100 r/min) for precise testing.
(5) Automatic stop function when preset cycles or time is reached.
