Tear strength is another important parameter to be determined for leather. A number of different tests are available, including the ‘trouser leg’ and ‘wing rip’ tests. However, an assessment developed specifically for leather is the ‘Baumann tear’ test. This is covered by the SATRA TM162:1992 test method – ‘Tear strength . Principle of Elmendorf Tear Test. It is measured by measuring the pendulum at a certain starting height to fall, all the potential energy into kinetic energy and then through the reduction of its potential energy converted into the work used to tear the fabric specimen, and then according to the original length of the textile sample to calculate the average tearing force.

The survey reveals that around 43% of the total surveyed units require all basic physical as well as chemical tests. Basic physical tests identified from the survey are tensile, stitch tear and tongue tear strength, flexing test, grain crack/distension, colour fastness, shrinkage test, water vapour permeability and water absorption. Result: The overall mean tear force across weft, in newton (N) or centinewton (cN). 2. Wing Rip Tear Test: The Wing rip tear test overcomes some problems which are found with the single rip test as it is capable of testing most types of fabrics without causing a transfer of tear.
