Three groups of tear test methods are described: 1. Tear in tension with application of a special notch. 2. Continuous trouser tear. 3. Continuous trouser tearing using tear element. It is shown that the methods of determining the tear resistance allow revealing the properties of materials taking into account the orientation processes occurring in the materials under loading. Current set of methods allows assessment of low modulus thermoplastics and elastomers by tear resistance.
