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).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. The test is performed using a pendulum impact tester, which .
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) . Tear resistance is of vital importance in the various functions of skin, especially protection from predatorial attack. . Before testing, . Department of Materials Science and Engineering .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
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 .What is Elmendorf Tear Tester?. The Elmendorf Tear Tester is a widely used instrument in material testing. It is specifically designed to measure the tear resistance of various materials, including films, paper, textiles, and non-woven fabrics.This testing method helps in assessing the material’s ability to withstand tearing forces, providing valuable insights into its quality and .

tear resistance test
1.1 This test method measures the force perpendicular to the plane of the paper required to tear multiple sheets of paper through a specified distance after the tear has been started, using an Elmendorf-type tearing tester. The measured results can be used to calculate the approximate tearing resistance of a single sheet. In the case of tearing a single sheet of .when 16 plies are torn together. For a 16-ply test specimen, the tearing distance K =163 4.3 cm (tearing distance per ply) 3 2 = 137.6 cm.
