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.Tearing Strength Tester. Tearing strength testing can be found in plastic film, paper and textile industries. It is used to describe how well a material can withstand the effects of tearing. Elmendorf tear is a common method that is used to test tear resistance.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 .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.There are three main standards which describe the fracture toughness testing of ductile alloys by generating tearing resistance curves: BS 7448-4 (1997), ISO 12135 (2016) and ASTM E1820 (2018). Each of these standards differs in significant details relating to the generation and analysis of the test data. Well, the force needed to tear the material is measured, and it offers a reliable indication of its tearing resistance.
