Elmendorf tear is the force needed to continue tearing a cut in materials such as nonwovens, textiles, paper and plastic film. Elmendorf tear testing equipment evaluates the tear resistance of a material using the propagation of tear by a pendulum (ASTM D1922). As a simulation of the Elmendorf tearing test, a tearing test method using a tensile tester was proposed with the same mode of fracture, mode III. Tear indices by both tests were highly correlated for various machine-made papers and laboratory handsheets. The relation between tensile strength and tear strength using the tensile tester was similar to that .

The Elmendorf-type tester is a pendulum that applies the force and measures a loss in the potential energy of the pendulum equating to the work done in tearing the paper. Smithers use an L&W single tear tester for papers and a James Heal Elmatear tester for heavier weight boards. Tearing index = Tearing strength/grammage, quoted in mN.m2/g.Explore paper tear strength tests according to ASTM D689 and ISO 1974. . The Elmendorf tear test, as outlined in standards like ASTM D689 and ISO 1974, is commonly used to assess the tear strength of paper products. This test helps manufacturers produce paper materials that are durable and fit for purpose.Tear Factor = (tearing strength)/(basis weight) = 100*a/b dm 2 Tear Index:, like tear factor, is defined as tearing strength divided by basis weight. The tear index, however, must be expressed in units of mN/(g f /m 2). As before, suppose that tearing strength = a g f and basis weight = b g f /m 2. The tear index is then given by

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).
Application GNP-1 Bursting Strength Tester can measure the bursting strength of single-layer or multi-layer paper, and can be used to test the blasting strength of cloth, leather, paper board, thin metal sheet, etc. Use mark transmission pressure, automatically retain the maximum bursting strength value when bursting, decomposition degree is 100 times higher than the needle type.
Another common application is in the paper industry to determine the tear strength of paper products. However, the test method is unsuitable for fabrics or other highly elastic materials. Elmendorf Tear Test Procedure: The procedure for this test is to cut a standardized sample of plastic film or sheet and place it in an Elmendorf tear tester .ASTM D624 includes two different definitions for tear strength based on the specimen type being tested. There are 5 acceptable test specimens described in this standard: Types A, B, C, T, and CP. When testing specimen types A, B, or C, the tear strength is defined as the maximum force divided by the thickness of the specimen.The mechanical version of the ProTear® Tear Tester.
