How is tear strength defined? What is the effect of this indicator on leather products?

Tearing force: A rectangular leather specimen of a specified shape (with a hole in the middle) is placed on the test hooks of the upper and lower jigs of the tensile tester, and the maximum load value reached when the tester is running is the tearing force of the specimen. Tearing force can also be interpreted as the ability of the leather to resist the tearing action of external forces.

Tearing force is an important indicator of the strength of leather, and is particularly important for leather garments. To ensure that leather garments are worn properly, they must be supported by a certain index of tearing force. Leather for garments is specified: sheep leather ≥1lN, cattle and horse leather ≥13N, other small animal skins ≥9N.
