Click Here to Request a Quote. Tear resistance is the measurement of a sample’s ability to resist tearing. Tear resistance can be impacted considerably by the speed of the test, e.g. test speed used in generate the tear. Tear propagation resistance for .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?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 .
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 Tear resistance testing measures the strength of a material when subjected to a point of rupture. The force required to tear the material is measured and recorded as the tear strength. It is a standard test method used in various industries and applications. Video 01:Tear Strength Single Tear Method The most common method [.]from Test Method D1004, wherein the specimen is strained at a rate of 50 mm (2 in.) per minute. However, specimen geometry and testing speed of the two test methods are dissimilar.The rate of tearing in this test method, while varying as a function of resistance to tear, is in the range from 7.6 to 46 m (300 to 1800 in.)/min.
5.1 Tear resistance of plastic film or sheeting is a complex function of its ultimate resistance to rupture. The specimen geometry and speed of testing in this test method are controlled to produce tearing in a small area of stress concentration at rates far below those usually encountered in service.This test allows manufacturers to determine the strength of the sample. This test complies with the following standards: ASTM D1004 Standard Test Method for Initial Tear Resistance of Plastic Film and Sheeting, and ASTM D5587 Standard Test Method for Tearing Strength of Fabrics by Trapezoid procedure. Nelson Labs is an active member of ASTM .
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.
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 crucial for textile manufacturers, designers, and quality control professionals. It ensures that their products meet industry standards.
5.1 Tear resistance of plastic film or sheeting is a complex function of its ultimate resistance to rupture. The specimen geometry and speed of testing in this test method are controlled to produce tearing in a small area of stress concentration at rates far below those usually encountered in service.
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 IndustryThe SLD-01 Tear Tester offers advanced features like PLC control, wide test range, and automatic data collection, ensuring accurate and consistent tear resistance testing. Why is tear resistance important in packaging materials? Tear resistance in packaging materials ensures that the packaging can protect its contents during transportation and .Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. . Tear resistance measures the ultimate force required to tear film or sheet. It is often used for quality control checks or for material comparison where tear failures are possible. Test Procedure:Testing Services; Customization. Transmission rate test of hazardous gases such as hydrogen and methane, etc. Transmission rate test of organic gases such as benzene, ester, alcohol and ketone, etc. . Elmendorf tear is a .
The ASTM D 1922 Tear Resistance test method 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.

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 . Tear Resistance Tear resistance testing is an important measure of a material’s quality and durability, as it provides information on how the material will perform under tearing stresses. This information is useful in product design and manufacturing processes, as well as in quality control and material selection. There are different test methods available for tear […]
Three standard methods are available for determining tear resistance of plastic films: ASTM D-1004 details a method for determining tear resistance at low rates of loading; a test in ASTM D-1922 measures the force required to propagate a precut slit across a sheet specimen; and ASTM D-1038 gives a method for determining tear propagation . Tear Resistance Test is professional designed for tensile strength, elongation test, peeling test and other physical properties test for flexible materials w.Application of Tearing Resistance Testing. Tearing resistance testing is crucial across various industries. For example: Packaging: Ensures that packaging materials can withstand the rigors of handling and transportation. Textiles: Assesses the durability of fabrics used in clothing and industrial applications.Sample Size. The Elmendorf tear test usually involves cutting certain standardized specimens from the plastic film or sheet. These specimens are usually 63 mm wide and should be large enough to fit the testing machine well, enabling precise and consistent measurement of tear resistance among different samples.
