Two specimens are . When it comes to textiles, tear strength is a crucial factor in determining the durability and quality of fabric. It refers to the resistance of a fabric to tearing under stress or force. Properly measuring tear strength is .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?
Standard Test Method for Tear-Propagation Resistance (Trouser Tear) of Plastic Film and Thin Sheeting by a Single-Tear Method 1.1 This test method covers the determination of the force necessary to propagate a tear in plastic film and thin sheeting (thickness of 1 mm (0.04 in.) or less) by a single-tear method.For edge-tear resistance see TAPPI T 470 "Edge Tearing Resistance of Paper (Finch Method)." Caution is recommended in interpreting results from weakly bonded sheets, especially those containing lightly refined long-fibered chemical pulps. The low rate of tear when multiple plies are torn simultaneously may produce erroneously high results.
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 .
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 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 .1.1 This test method 2 covers the determination of the tear resistance of flexible plastic film and sheeting at very low rates of loading, 51 mm (2 in.)/min. and is designed to measure the force to initiate tearing. The specimen geometry of this test method produces a stress concentration in a small area of the specimen. The maximum stress, usually found near the onset of tearing, is .
1.1 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 specimen.1.1 This test method 2 covers the determination of the tear resistance of flexible plastic film and sheeting at very low rates of loading, 51 mm (2 in.)/min. and is designed to measure the force to initiate tearing. The specimen geometry of this test method produces a stress concentration in a small area of the specimen. The maximum stress, usually found near the onset of tearing, is .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) .
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 .The maximum stress, usually found near the onset of tearing, is recorded as the tear resistance in newtons (or pounds-force). The method is not applicable for film or sheeting material where brittle failures occur during testing or where .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

It can also be used for boards having a low grammage if the tearing . 4.1 This test method is of value in ranking relative tearing resistance of various plastic films and thin sheeting of comparable thickness. Experience has shown the test to have its best reliability on relatively less extensible films and sheeting. Variable elongation and oblique tearing effects on the more extensible films preclude its use as a precise production-control .
