Tear propagation resistance for the purpose of acceptance testing is common with materials such as paper and rubber. 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).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?
One way to measure tear resistance is through the Pendulum Method or Elmendorf Tear Test, as defined by ASTM D1922. The Elmendorf Tear Test is a simple and reliable way to measure the force required to propagate a slit in a plastic film a fixed distance to the edge of the test sample. The test is performed using a pendulum impact tester, which .Purpose of a tear test: The overall goal of a tear test is to determine a materials ability to resist the growth of the initial tear or its “tear resistance”. The value of a material’s tear resistance is generally accepted to be the force required to complete the tear so that it has gone completely though the material so that it has been .This Complete Guide of the Elmendorf Tear Testing explores tear resistance testing dimensions, application areas, standards, methodologies, troubleshooting, and the future landscape of tear analysis. Key takeaways and practical insights empower informed decisions in material science. Application of Elmendorf Tear Testing in Industrypropagate a tear initiated under specified conditions. 3.2.5.1 Discussion—The trapezoid tearing force may be calculated from a single peak or a multiple-peak force-extension curve. 3.2.6 tearing strength, in fabrics, n—the capacity of a fabric to withstand the tearing force required to propagate a tear after its initiation. 4. Summary of .
Elmendorf Tear (high speed pendulum test) Trouser Tear (low speed using standard tensile test apparatus). Elmendorf tear. The test piece is clamped and a cut introduced such that when the pendulum is released, a tear is propagated from the cut at high speed. The tear resistance is measured as the average force in mN propagating the tear to the .ISO 1974:2012 specifies a method for determining the (out-of-plane) tearing resistance of paper. It can also be used for boards having a low grammage if the tearing resistance is within the range of the instrument. ISO 1974:2012 does not apply to corrugated fibreboard, but it may be applied to the components of such boards.5.2 The trapezoid tearing strength method is useful for estimating the relative tear resistance of different fabrics or different directions in the same fabric. 5.3 This test method may be used for acceptance testing of commercial shipments; however, caution is advised since information about between-laboratory precision is incomplete.ISO 6383-1:2015(E) 8 Number of test specimens 8.1 A minimum of five test specimens shall be tested in each of the required directions of testing. 8.2 Specimens which show a tear out of line to the extent that the tear reaches one of the edges of the test specimen shall be discarded and further specimens tested (see 11.3). 9 Speed of testing
