What is the flexing resistance test?

Flexing resistance refers to the degradation or even destruction of the physical properties of a material or product under repeated flexing action. In flexing testing of rubber and coated fabrics, flexing resistance is usually expressed in terms of the number of times a specimen has been subjected to repeated flexing and the degree of surface cracking.

Test standards for flexing resistance of rubber and coated fabrics

ISO 7854: Rubber or plastics coated fabrics – Determination of resistance to damage by flexing
GB/T 12586: Rubber or plastics coated fabrics – Determinaiton the flexing resistance to damage

Scope: This international standard describes three methods of assessing the resistance of rubber or coated fabrics to damage by repeated flexing.

  • Method A: Demattia Flexing Method
  • Method B: Schildknecht Flexing Method
  • Method C: Crumple Flexing Method

How to test the flex resistance of rubber or coated fabrics?

Fold a rectangular strip of coated fabric twice so that its long edges meet to form a 125 mm * 12.5 mm strip. Mount this folded strip between a pair of flat clamps. One of the clamps reciprocates, causing the folded test piece to bend outwards five times per second. This high-speed folding of the test piece is continued for either a pre-set number of cycles or until damage to the test piece is apparent.

DeMattia Flexing Tester, to determine the resistance of rubbers, leather and coated fabrics to the formation and growth of cracks, damages by repeated flexing. Demattia flexing tester complies with standards EN ISO 7854 Method A, ISO 7854 Method A, GB/T 12586 Method A. In addition, TESTEX also offers the flexing machine for method B – Schildknecht method and method C – Crumple/flex method.
