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 .C680M elmendorf Tearing Tester is suitable for testing tear resistance of film, sheet, soft PVC, PVDC,water-proof roll, woven material, polyolefin, polyester, paper, paperboard,textile and non-woven fabric, etc. .

However, specimen geometry and testing speed of the two test methods are dissimilar.The rate of tearing in this test method, while varying as a function of resistance to tear, is in the range from 7.6 to 46 m (300 to 1800 in.)/min.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.

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 . 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.

When you're evaluating fabric performance, wear and tear resistance becomes a critical measure. This characteristic guarantees that the fabric maintains its integrity, appearance, and .Purpose: This test method is used to determine the average force (grams) to propagate tearing through a plastic film in machine and/or transverse direction. Sample: We usually need about one (1) square foot of plastic film for each test direction. Price & Delivery: Contact us for a quote. Basic Description: An impact tester with a pendulum is used to measure the force (grams) .
General paper property that takes into account two measures of a paper's ability to withstand being torn. Internal tearing resistance refers to the work required to tear a paper sample through a specified distance once the tear has been started. Edge tearing resistance refers to the work required to tear a paper sample by starting the tear at the edges of the sheet.
