The Autoline Tear method was developed in 1995 by Lorentzen & Wettre, and has become the de facto standard (ISO 18 522) for automated tear strength testing. The tear strength of paper, as measured by the Elmendorf tester, is one of the most important mechanical properties of paper. . tear strength test for characterizing pulps. TAPPI 74(8):109- 113 9. Yamauchi T, Tanaka A (200I) Heat generation around fracturing point during the tearing process of paper. .
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 . Tear tester for paper strength. The working principle of tear measuring instrument. The tear tester is designed according to the principle of function, and its working process is very precise. When the center of mass of the sector pendulum of the tearing degree meter rises to the height to be torn, the sector pendulum is released to change the .

Tear resistance (or tear strength): an engineering measurement of how well a material can withstand tearing. The test is useful for a wide variety of materials by many different test methods. For paper, tear resistance is the force required to tear a single ply of paper after the tear has been started. Materials: 1 large metal paper clip ,1 pen .
Baumann Tear Test: Often used for paper and card materials, where a central cut is made and force is applied to propagate the tear. Standards: TAPPI T414 (for paper). . How to do a tear strength test? A tear strength test involves .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.Electronic Tearing Tester is an intelligent testing instrument used to measure the tearing performance of sheets such as paper and cardboard. It is widely used in the field of testing paper materials by universities, research institutes, quality inspection departments, and paper printing and packaging production departments. Application RangeOn the other hand, to compute the tear factor of the material, compare the quality of two papers. This will helps to measure the strength of two different material efficiently. Tear Factor = Tearing Resistance of Paper / Substance. Presto Stantest offers best quality of Tearing Strength Tester to measure the tearing resistance of the materials .

It is widely used in the field of testing of paper materials in colleges and universities, research institutes, quality inspection departments, and paper printing and packaging production .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.
1.1 This test method measures the force perpendicular to the plane of the paper required to tear multiple sheets of paper through a specified distance after the tear has been started, using an Elmendorf-type tearing tester. The measured results can be used to calculate the approximate tearing resistance of a single sheet. In the case of tearing a single sheet of .Electronic Tearing Tester is an electronic tear tester developed to determine the tear properties of paper or low-quantity paper and corrugated paper. It is widely used in the field of testing of paper materials in colleges and universities, research institutes, quality inspection departments, and paper printing and packaging production .
Tear Tester which was designed by Dr. Thwing and Mr. Armin Elmendorf. This method, developed over a century ago established the industry standards used worldwide today to measure tear strength. The ProTear Testers provide a rapid and precise way to evaluate the tear resistance of sheet materials includingThis test is important for examining the strength of corrugated paper which is used in most packages. Tear Strength/Resistance: Tear strength or resistance means the strength or ability of the paper to resist tearing. This is a significant test to establish the extent to which paper can afford to be torn when being printed or used in packaging.
