It is often used for quality control checks or for material comparison where tear failures are possible. Test Procedure:
Tear resistance can be impacted considerably by the speed of the test, e.g. test speed used in generate the tear. Tear propagation resistance for the purpose of acceptance testing is common with materials such as paper and rubber. Tear resistance in textiles involves the load required to propagate a single “rip-tongue” type of tear (tear .The tear resistance of a material, also called tensile strength at break, is the mechanical tensile stress at the exact moment of tearing and is also given in N/mm² or MPa. Since the maximum tensile stress and the tensile stress at the moment of rupture are usually identical for elastomers, the two terms are often used synonymously.
Reduction of tear resistance as a consequence of defects in soft biological tissues is relevant for a number of medical problems. . Polym. Test. 60, 117–123 (2017). Tear resistance is the measurement of a sample’s ability to resist tearing. Tear resistance can be impacted considerably by the speed of the test, e.g. test speed used in generate the tear. Tear propagation resistance for the purpose of acceptance testing is common with materials such as paper and rubber.
The tearing strength tester is an appropriate tool to measure the tear resistance of various materials including textiles and fabric. Types of tear test: Tongue Test; Trapezoid; Elmendorf; Measurement of fabric tearing strength: Elmendorf tear tester: Sample Preparation: First we take specimen of 100 ×75 . scope: This test method 2 covers the determination of the average force to propagate tearing through a specified length of plastic film or nonrigid sheeting after the tear has been started, using an Elmendorf-type tearing tester. Two specimens are cited, a rectangular type, and one with a constant radius testing length. The latter shall be the preferred or referee .The mean force required to continue the tearing of an initial cut in a single sheet of paper is expressed as the internal tearing resistance. If the initial slit is made in the machine direction, the result is given as machine direction tearing resistance and similarly for the cross-machine direction (ISO 1974). Why measure tearing resistance?5.1 This test method is of value in rating the tear-propagation resistance of various plastic films and thin sheeting of comparable thickness. For highly extensible film or sheeting the deformation energy of the specimen legs is significantly greater than the tearing energy. The tear-propagation resistance in slightly extensible or non-extensible film or sheeting is distinguished from the .
