Frequently Asked Questions (FAQ)
Q1: What is the primary purpose of the ROSS Flexing Tester?
A: The ROSS Flexing Tester is specifically designed to determine the resistance of vulcanized rubber, shoe soles, PU, PVC, TPR foam, and similar materials to cut growth during repeated bending and flexing cycles.
Q2: How many test specimens can the machine handle at one time?
A: The tester features 6 sets of fixtures, which allows it to test up to 12 pieces of specimen samples simultaneously, increasing testing efficiency.
Q3: What are the differences between models ULB-F33-A and ULB-F33-B?
A: The main differences lie in their bending speeds and testing standards. ULB-F33-A operates at 100±3 cpm (complying with ASTM D1052), while ULB-F33-B operates at 60±5 cpm (complying with SATRA TM60, ISO 5423, and others). Specimen dimensions and standard chisel cutters also differ slightly between the two models.
Q4: Does the ROSS Flexing Tester shut off automatically?
A: Yes. The tester is equipped with a digital LCD counter. You can preset the target number of cycles, and the machine will automatically stop once the preset count is reached.
Q5: What standard accessories are included with the machine?
A: The machine comes with 1pc of power line and 1pc of chisel cutter (2.5mm for ULB-F33-A or 2mm for ULB-F33-B) depending on the model chosen.
