Testing the Tear Resistance of Leather, Textiles and Flexible Materials
Our laboratory performs tear tests professionally and in accordance with national and international standards, including accredited test procedures according to DIN, DIN EN, DIN EN ISO and ASTM as well as specifications from GMW and PSA.
These physical test methods are used to determine the tear resistance of materials, i.e. their resistance to the propagation of an existing weakness, notch or tear under tensile loading. In a tear test, a standardized initial tear or cut is introduced into the specimen and the force required to propagate the tear is determined. Unlike a tensile strength test on an undamaged specimen, tear testing specifically examines the behavior of a material after a tear has already been initiated.
Tear resistance is particularly relevant for leather, artificial leather, textiles, coated textiles, films and other flexible sheet materials. Material structure, fibre or yarn direction, weave or bonding structure, coating, thickness and layer construction can significantly influence tear propagation.
Depending on the material and test principle, we offer tests using the Single Edge Tear, Trapezoid Method and Double Edge Tear.
Tear tests form part of Strength Properties and Deformation Behavior. Further mechanical and physical material tests are listed in our overview of Physical Testing.
