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 […]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?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.
Elmendorf tear testing is a critical method for assessing the tear resistance of various materials, . By adhering to industry standards and using reliable testing equipment like the SLD-01 Tear Tester, companies can produce materials that meet the highest quality standards. FAQ.
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 .Our Company. Careers Subscribe to Our Newsletters. . 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 .
ASTM D1004 Tear Resistance This test method covers the determination of the tear resistance of flexible plastic film and sheeting at very low rates of loading, 51 mm (2 in.)/min. and is designed to measure the force to initiate tearing. The specimen geometry of this test method produces a stress concentration in a small area
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.Elmendorf tear is a common method that is used to test tear resistance. Elmendorf Method C680M Elmendorf Tear Strength Tester. ISO 6383-2 - Plastics -- Film and sheeting -- Determination of tear resistance -- Part 2: Elmendorf .Scope: Tear Resistance test by ASTM D1004 is used as a quality control check for flexible plastic material comparison where tear failures are suspected in sheets and films.

Why is tear resistance important in packaging materials? Tear resistance in packaging materials ensures that the packaging can protect its contents during transportation and . 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 .
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. Fracture toughness characterizes the ability of a material to maintain a certain level of strength despite the presence of a macroscopic crack. Understanding this tolerance for defects in soft .
Tear resistance is one of the properties that make a plastic film strong. It proves to be crucial for its durability if the material is subjected to tear events. When testing a film's tensile strength, tensile modulus and tear resistance are often used in conjunction to provide a comprehensive picture of its strength. ASTM D1004 Test MethodThe 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.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.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.
