Tearing test for paper using a tensile tester Received: July 4, 2001 / Accepted: January 7, 2002 Abstract As a simulation of the Elmendorf tearing test, tearing test method using a tensile tester was proposed . The tear strength of paper, as measured by the Elmendorf tester, is one of the most important mechanical properties of paper. .Paper strips are cut from the test sheet at an angle of 30° and -30° to the machine direction. The tensile strength is determined on both strips. What are the benefits of this analysis? The difference in tensile strength is a parameter for the deviation of the main fibre direction from the machine direction.

TENSILE STRENGTH OF PAPER REVISITED Kaarlo Niskanen, Jari Sirviö and Rolf Wathén KCL Science and Consulting, P.O.Box 70, FIN–02151 ESPOO, FINLAND . areas at the onset failure in the ordinary tensile test, in order to obtain a reliable measure for the critical defect size a. It is also possible that the meas-Tensile strength Papermakers use precise methods to test the strength of paper. They measure the tensile strength of paper by determining how much stress the paper can withstand before tearing apart. The intended use of a paper indicates the tensile strength it must have. For example, wrapping paper must have higher tensile strength than paper .Because some paper products such as towels, sanitary tissues, and filter paper are subjected to wetting by water in their normal use, wet tensile testing has become important. This test is essentially the same as that for dry tensile strength, except that the specimen is wetted. Paper that has not been specifically treated to produce wet . What is a tensile test?In the field of materials science and engineering, a tensile test is a widely used method to determine the mechanical properties of a material, specifically its response to tensile forces. It involves subjecting a specimen to an ever-increasing tensile load until it reaches its breaking point. By measuring the applied force and the resulting deformation .
tensile strength of paper meaning
In the wet tensile test the strength of the paper (or tissue) is determined while in a wet state. Wet tensile tests on paper are performed according to ISO 3781 or TAPPI T 456.If paper is used or processed in a wet state, wet strength is one of its most important material properties.PULP, PAPER & PAPER BOARD TESTING.

The tensile stress at which this takes place is the tensile strength of that material, in this case paper. When excessive tension is applied, both ductile, as well as brittle materials will approach a point of failure.
This test is used to measure the tensile strength and elongation of paper or board in the machine direction (MD) and the cross direction (CD). Even small variations in tensile strength can affect the functionality of the product. Paper and board must withstand certain forces during manufacturing, transportation, shipping, and use. The tensile testers or technicians will calculate the tensile strength, yield strength and ductility of the material. After taking the final measurements, the broken specimen will be compared to the undamaged copy made before the test. The tensile strength will determine the material’s maximum tensile stress.
