A tear in a fabric or garment generally occurs progressively along a line, and can be initiated by a moving fabric being caught on a sharp object. Several methods are used to measure tear strength, e.g. double tongue rip (tear) test, trapezoid tear test, (ASTM D5587) and single tongue tear test (ASTM D2661, BS 4303).The Elmendorf Tear Tester also allows for testing specimens in different orientations, enabling assessment of both the machine direction (MD) and cross-machine direction (CD) tear resistance. Understanding the tear resistance of materials is vital for manufacturers to ensure product quality, optimize material selection, and meet industry standards.
tear resistance tester
Result: The overall mean tear force across weft, in newton (N) or centinewton (cN). 2. Wing Rip Tear Test: The Wing rip tear test overcomes some problems which are found with the single rip test as it is capable of testing most types of fabrics without causing a transfer of tear. During the test the point of tearing remains substantially in line with center of the grip. The Elmendorf Tear Strength Tester is an instrument specially used to test the tear strength (strength) of fabrics. It uses the impact pendulum method to measure tear strength, also known as the pendulum or falling weight tear strength tester. There are manual electronic tear strength testers, digital Elmendorf tear strength testers, etc.
12.2.1 Elmendorf tear strength for each test direction and test condition, as required. 12.2.2 Test conditions (with or without wetting). 12.2.3 Puckering, if it occurs during the test. . 13.2 Elmendorf Tear Strength, Standard Equipment, Interlaboratory Test Data – Interlaboratory testing was conducted in 1994-1995 with samples of three .Tear resistance testing can be found in plastic film, paper and textile industries.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.Test Method: SATRA TM162 Tear strength - Baumann method April 2017. SCOPE. This method is intended to determine the force required to tear a material. The method is applicable to all types of leather and is generally not used with any other type of material. . The slot is then pulled open by a tensile testing machine causing the material to .There are 3 standard samples for Elmendorf Tear testing. The preferred test sample for plastic films is the constant radius sample. This sample provides a constant radius from the start of the tear strength measurement - useful for materials where the tear may not propagate directly up the sample as intended.

Test Method: SATRA TM30 Tear strength - trouser leg method April 2017. SCOPE. . Calibration and verification of static uniaxial testing machines. Tension/compression testing machines. Calibration and verification of force-measuring system. HISTORY. First issued January 1968. Revised August 1980, August 1988, September 1995, April 2017.The tear strength of thermoset rubbers, thermoplastic elastomers, and silicones can be measured according to specification ASTM D624. The test measures the strength required to initiate a tear in a material. D624 describes multiple different types of sample shapes that can be tested in a standard universal testing machine (tensile testing machine).For example, with rubber, tear resistance measures how the test specimen resists the growth of any cuts when under tension, it is usually expressed in kN/m. [2] Tear resistance can be gauged via the same ASTM D 412 apparatus used to measure tensile strength, modulus and elongation.ASTM D 624 can be applied to measure the resistance to the formation of a tear . Q: What are the relevant standards of textile tearing strength testing? At present, the most commonly used method of fabric tearing strength test is mainly the pendulum method, tongue method and trapezoidal method. Aside from these three methods, there is also Wing method, rectangle method and nail method used nationally. Table 1 shows the relevant.

Imagine a piece of clothing, like denim jeans, that easily rips at the seams due to everyday wear. Or consider upholstery fabric that tears prematurely when brushed against. The Elmendorf Tear Test helps prevent such scenarios by providing a quantitative measure of a fabric’s tear strength. The test operates on a straightforward principle. There are two separate tear strength testing methods: tongue tear and trapezoidal tear. They both require specific preparations in order to be accurate. As the names suggest, in tongue tear tests the fabric is cut to form two tongues at the end of the rectangle, while the trapezoidal tear testing requires the material to be cut into a trapezoid .

A sample is clamped to the upper and lower jaws of the test machine. It is oriented such that the stress is applied as a tearing motion.The Heavy Duty Tear Tester/Heavy Duty Elmendorf tests fabrics such as canvas, sailcloth, and denim. Thwing-Albert’s Heavy Duty Tear Tester uses the same software as our standard ProTear® Tear Tester, and this rugged instrument tests up to 25,600 grams to measure Elmendorf Tear Strength. The Elmendorf Tear Test uses three standard sample types, including the constant radius sample, the 63mm x 76mm rectangle, and a modified rectangle for textiles. The constant radius sample is the preferred test sample for plastic films, as it provides a constant radius from the start of the tear strength measurement.
