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 testingGeneral 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. Fabric tear resistance is crucial for safety, product durability, and customer satisfaction. The Elmendorf test is a standardized method widely used across industries. It helps quantitatively .tested. Therefore, the tearing resistance is expressed in maximum newtons (or pounds-force) of force to tear the specimen. 5.4 The tear resistance of plastic film may be a specification that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification.

Understanding the Tearing Resistance Tester: An In
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 .mandrel (5.3) through both the holes in the test piece holder and the slit in the test piece. 7.4 Clamp the free end of the test piece in the lower jaw of the tensile testing machine. 7.5 Run the tensile test machine until the test piece is torn apart and record the maximum force, in newtons, recorded during the tearing. Research on the tearing of fabric membranes has a long history, which can be traced back to 1915. 8 At that time, the trapezoidal tearing test and tongue (single tongue and double tongue) tearing tests were widely used in the garment field. In 1945, Krook 9 studied the single-tongue tearing of woven fabrics and proposed the concept of a del-zone for the first time.
