Modernize tear resistance testing equipment to align with energy-efficient practices, reducing the overall carbon footprint. . +86 769 2329 4860 Email: [email protected] [email protected] . The resistance to tear propagation is classified based on visible observations and qualitative judgments. The tongue tear test is precious for fabric, where stretch and flexibility are fundamental elements in tear resistance assessment, and it includes activities such as clothing, swimming wear, and medical textiles.This method determines the tearing resistance of low-grammage paper or board with the Elmendorf method. During the test, an initial cut is made on the test specimen. This cut is then torn for a given distance using a pendulum. The work required to tear the test piece is measured, and the mean tearing force is calculated.

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 .
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?The Elmendorf Tear Tester, also known as a tearing resistance tester, complies with ASTM D1424, BS ISO 13937-1, GB/T 3917.1, and ISO 4674-2.Tear resistance of rubber is the force required to tear a 1 inch thick specimen under the conditions outlined in ASTM D-624. Tear resistance of textiles is the force required to propagate a single-rip tongue-type tear (starting from a cut) by means of a falling pendulum apparatus. (ASTM D-1424) 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 .
The tensile strength of a material is the maximum mechanical tension it can withstand before it cracks. It is given in N/mm² or MPa. 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 .
This Complete Guide of the Elmendorf Tear Testing explores tear resistance testing dimensions, application areas, standards, methodologies, troubleshooting, and the future landscape of tear analysis. Key takeaways and practical insights empower informed decisions in material science. Application of Elmendorf Tear Testing in IndustryISO 1974 was prepared by Technical Committee ISO/TC 6,Paper, board and pulps, Subcommittee SC 2, Test methods and quality specifications for paper and board. . This International Standard 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 .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 .
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 . 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 .
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.Material between those two extremes has been shown to reliably use ASTM D1004 to compare tear resistance between materials. Materials Testing System. Due to the low forces involved in ASTM D1004 testing, we recommend a .
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.
