Ross Flex Tester

ASTM D1052 is an industry-standard test method that measures the ability of the material to withstand the formation and growth of a cut or crack when subjected to repeated bending stresses.

The test involves clamping one end of the test specimen to a holder's arm while the pierced end is placed between two rollers that permit a free bending movement of the test specimen during the test. The pierced area of the test specimen is bent freely over a 10-mm (0.4 in.) diameter rod through a 90° angle at a specified frequency. After a specified number of test cycles, the length of the notch of the test piece is measured, and the zigzag resistance of the test sole relative to the notch growth rate is evaluated.

The NextGen Ross Flex Tester is designed to test virtually any flexible sheet-like material, including PU, PVC, and TPR foams. It also complies with ASTM D1052 standard.

ISO 5423 is a standard that specifies determining the resistance of rubber and plastics to flex cracking. You can apply it to both vulcanized and thermoplastic materials. Moreover, it is applicable to any material that can be formed into a sheet-like shape.

ISO 5423 test method involves subjecting a test specimen to continuous flexing at a specified frequency and bending angle until a crack or cut is observed. The test specimen is in the form of a V-shape, and the apex of the V is subjected to the flexing motion. The test is performed at room temperature and under controlled conditions to ensure reproducible results.

ISO 5423 specifies the number of test cycles, the bending angle, and the bending frequency required for the test and provides a rating system for evaluating the degree of cracking or cut growth.

The damage and cracking degree of the specimen after the Ross Flex Test is evaluated by measuring the length of the notch of the test piece. The notch is the area where the material is subjected to the most stress during the test and is prone to damage and cracking. After a specified number of test cycles, the operator will measure the length of the notch to determine the degree of damage.

The degree of damage is evaluated based on the test specimen's zigzag resistance relative to the notch growth rate. The zigzag resistance is the material's ability to withstand repeated bending without cracking or breaking. A higher zigzag resistance indicates a more durable material.

The notch growth rate is the rate at which the damage to the notch increases over time due to repeated bending. The rate is measured by taking multiple readings of the notch length during the test. The length of the notch is plotted against the number of test cycles to determine the growth rate.

NextGen Material Testing Ross Flex Tester is designed to test the resistance of flexible sheet-like materials, such as vulcanized or synthetic elastomers, to cut growth. It is used for shoe soles, but it can be used to test various flexible materials. However, keep in mind that the tester clamps the end of the test specimen to the holder's arm while the pierced end is placed between two rollers which must permit a free bending movement of the test specimen during the test. Therefore, the material being tested needs to have a sheet-like shape in order to be clamped and flexed by the machine.

For non-sheet-like materials, other testing machines may be more appropriate. For example, NextGen Universal Testing Machines are designed to test a wide range of materials, including metals, plastics, and textiles.
