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).A tear test applies a force to a material that already contains a partial fracture or rupture otherwise known as a “tear” in order to bring the material to complete failure. This is done by placing the test sample into a tensile testing or universal test machine so that the section on one side of the fracture is pulled up and the section on .ASTM D624 is a testing standard for measuring the tear strength of thermoset rubbers, thermoplastic elastomers, and silicones. This standard describes multiple different types of sample shapes (Type A, B, C, T, and CP) that can be tested in .
The specimen geometry and test speed are not intended to simulate real world tear conditions; instead, ASTM D1004 is intended to create a controlled tear of to analyze force versus displacement data for quality control or material comparison purposes. ASTM D1004 is not applicable for plastic material where brittle failure occurs or where . Standard Test Method for Tearing Strength, Tongue Tear of Leather D4704-13R17 ASTM|D4704-13R17|en-US Standard Test Method for Tearing Strength, Tongue Tear of Leather Standard D4704 Standard Test Method for Tearing Strength, Tongue Tear of Leather> new BOS Vol. 15.04 Committee D31 $ 73.00 In stock 5.2 Tear strength may be influenced to a large degree by stress-induced anisotropy (mechanical fibering), stress distribution, strain rate, and test piece size. The results obtained in a tear strength test can only be regarded as a measure under the conditions of that particular test and may not have any direct relation to service performance.

The ASTM D1424 Elmendorf based tear test is the most popular test for measuring the tearing strength of most fabrics. The Elmendorf test testing machine uses a falling pendulum to tear a fabric specimen. It measures the amount of energy required to perform the tearing operation by measuring the peak follow-through angle of the pendulum after .
The Tongue Tear Test (ASTM D2261) is an essential technique for evaluating the tearing strength of textiles and offers insightful data regarding their resilience to tearing across a range of industries. This standard assists in acquiring of accurate and consistent measurements for various fabrics by manufacturers, designers, and quality control .
ASTM D1004 is a standard test method for the determination of tearing resistance of plastic film and sheeting. It gauges the force required to detach a specimen from its backing material by pulling it until it tears. . ASTM D1004 test method focuses on the tear resistance of flexible plastic film and sheeting at very low speed test rates of .
1.3 Tearing strength, as measured in this test method, requires that the tear be initiated before testing. The reported value obtained is not directly related to the force required to initiate or start a tear. . ASTM grants Licensee a limited, revocable, nonexclusive, non-transferable license to access, by means of one or more authorized IP . Significance and Use 5.1 The significance of the tear test is similar to that of the notch-tensile test, and its primary usefulness is as an indicator of toughness or as a ranking test as described in Test Method E338 and Practice B646. 5.1.1 This test m . ASTM grants Licensee a limited, revocable, nonexclusive, non-transferable license to .Propagation Tear Resistance of Plastic Film and Thin Sheeting by Pendulum Method (Elmendorf Tear) ASTM D1922. Scope: A pendulum impact tester is used to measure the force required to propagate an existing slit a fixed distance to the edge of the test sample. One use of these results would be for the specification of material and thickness for . Scope1.1 This test method is an index test used to measure the force required to continue or propagate a tear in woven or non-woven geotextiles by the trapezoid method. While useful for quality control and acceptance testing, the trapezoid tear test does

The values given in parentheses are provided for information only.
ASTM E436 testing covers the drop-weight tear test (DWTT) on ferritic steels with thicknesses between 3.18 and 19.1 mm (0.125 and 0.750 in.). Results may be used to determine the appearance of propagating fractures in plain carbon or low-alloy pipe steels (yield strength less than 825 MPa).To perform a test to ASTM D903, the adhesive materials must be cut into specimens 1" x 12" long. The specimens are then peeled away from either a flexible or rigid substrate at a 180° angle at a separation rate of 152.4 mm/min, or 6in/min. Test materials must be thick enough to withstand the expected tensile pull but not greater than 3 mm (1 .1.2 Constant-Rate-of-Gri p Separation Test-This test method employs a constant rate of separation of the grips holding the test specimen. 1.2.1 Specimen extension shall be measured in this test method by grip separation. 1.3 The values .
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 . ISO 257-3), the dart impact test (ASTM D1709, ISO 7765), and the Elmendorf tear test (ASTM . D1922, ISO 6383-2) are variations of the same mechanical test but they greatly differ in testing .ASTM D1922 Elmendorf Tear Test Scope: All plastic films and sheets are prone to tear with increased force. The ASTM D1922 test method is widely used to rank the relative tear resistance of thin plastic films and sheets.
