Bally Leather Flexing Tester
1. Product Introduction & Applications
The Bally Leather Flexing Tester (Flexometer) is designed to evaluate the flexural resistance of leather and similar materials under continual flexing. This 12-station flex tester allows for flexible station arrangement and easy sample installation, providing reliable assessment of leather durability and cracking propensity.
Applications:
Testing the flexural resistance of leather, light leathers, and surface trims.
Assessing the propensity of materials to crack, simulating creases formed in shoe uppers during walking.
Complementary testing alongside shoe upper flex testers.
Pre-treatment of specimens prior to water vapor permeability testing, especially for protective footwear.
2. Conformity Standards
EN ISO 20344:6.6 — Personal Protective Equipment, Test Methods for Footwear
UNI 4818 — Polymeric materials, coated fabrics, Test Methods
DIN 53.351 — Inspection of leather, artificial leather, and similar flat fabrics
UNE/I.U.P. 20, I.U.P.10+20 — Leather testing methods
3. Product Advantages
