The maximum bending angle of NextGen’s Ross Flex Tester is 90 degrees, with a tolerance of +/- 20 degrees. During each test cycle, the pierced area of the test specimen is bent freely over a 10-mm diameter rod through a 90-degree angle, in accordance with the industry standard.

This parameter evaluates the resistance of vulcanized or synthetic elastomers to cut growth. By subjecting the material to continuous flexing at a fixed angle, the machine can determine the material’s ability to resist cracking or damage over time.

NextGen’s Ross Flex Tester is designed to operate at a frequency of 1.7 ± 0.08 Hz (100 ± 5 cpm) in order to provide consistent and repeatable results. The machine is also capable of testing up to 12 specimens simultaneously, which enables efficient testing of large batches of materials.
