The GESTER GT-KB05D Whole Sole ROSS Flexing Tester is an advanced laboratory physical testing instrument specifically designed to measure the flex resistance, crack initiation, and cut growth rate of complete, intact shoe soles made of rubber, PU, PVC, and TPR foam materials. Unlike standard material strip testers, the GT-KB05D evaluates non-cut outsoles directly under continuous 90° rectangular flexing, preserving the natural tread design and structural pattern. Fully compliant with ASTM D1052, SATRA TM60, ISO 5423, and BS 5131, it offers 3 stations, 6 stations, precision surface-oxidized aluminum clamps, and an automated LCD digital counter for high-precision footwear quality control.
