A tear in a fabric or garment generally occurs progressively along a line, and can be initiated by a moving fabric being caught on a sharp object. Several methods are used to measure tear strength, e.g. double tongue rip (tear) test, trapezoid tear test, (ASTM D5587) and single tongue tear test (ASTM D2661, BS 4303).

ISO recognizes IULTCS as an international standardizing body for the preparation of test methods for leather.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.Eurofins | BLC offer a variety of leather tear strength tests for multiple end uses: BS EN ISO 3376:2020 - Tensile strength and percentage extension; BS EN ISO 3377-1:2011 - Tear load – single edge tear .

ASTM D624 includes two different definitions for tear strength based on the specimen type being tested. There are 5 acceptable test specimens described in this standard: Types A, B, C, T, and CP. When testing specimen types A, B, or C, the tear strength is defined as the maximum force divided by the thickness of the specimen.This force is then divided by the thickness of the material to give the stitch-tear strength of the material.

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.
