ISO 23910

ISO 23910:2019 is used for determining the stitch tear resistance of leather materials under controlled tensile loading conditions. The standard helps manufacturers evaluate the resistance of leather against tearing and seam failure around stitched areas used in footwear, garments, upholstery, automotive interiors, bags, belts, and leather accessories. Stitch tear testing plays an important role in studying how leather materials perform under stress concentration near stitching points where tearing and edge splitting commonly occur. The standard supports quality verification, material comparison, supplier evaluation, and product development activities for different leather applications. Presto offers advanced tensile testing systems suitable for stitch tear resistance testing with accurate force measurement, controlled extension rates, and software based result analysis.

This standard covers the determination of stitch tear resistance for different leather materials using specially prepared test specimens with a defined slit arrangement. During testing, a metal mandrel is inserted through the slit and tensile force is applied at a controlled speed until tearing occurs. The testing system continuously records the maximum force required for tear propagation. Multiple specimens are tested in both parallel and perpendicular grain directions for accurate performance evaluation under standardized laboratory conditions.

ISO 23910 is widely used for evaluating stitch tear resistance and seam durability of leather materials used in industrial and commercial applications. Presto provides advanced tensile testing systems suitable for leather tear resistance testing with stable gripping systems, controlled loading conditions, and software based reporting solutions for laboratory and production quality control environments.
