Frequently Asked Questions
What materials can be tested with the ROSS Flexing Tester?
The ROSS Flexing Tester is designed to test rubber products, shoe soles, PU, PVC, TPR foam, and other flexible materials by continuously stretching and bending them to measure durability and resistance to cracking.
How many specimens can the machine test simultaneously?
Both models (ULB-F33-A and ULB-F33-B) are equipped with 6 sets of fixtures, allowing you to test up to 12 pieces of sample specimens at the same time.
What is the difference between Model ULB-F33-A and Model ULB-F33-B?
The main differences are the bending speed and testing standards. Model A operates at 100±3 cpm and complies with ASTM D1052. Model B operates at 60±5 cpm and complies with standards like SATRA TM60, ISO 5423, and ISO 4643.
