The proposed tearing test is convenient especially for imaging techniques such as thermography, and can help give new insights into the tearing process of paper. Key words Elmendorf tear 9 Fracture 9 Paper 9 Tearing 9 Test methods introduction The tear strength of paper, as measured by the ElmendorfCited by: 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 by: ThJ different test methods included in the study are: singlel rip test, tongue double rip test, wing rip test, trapezoid test, impact tear test (performed using Elmendorf tester) and wound bursting strength test (burst~ng tear test).
The Website provides practice using the M.A.A.R.I.E. framework, interactive flaw-catching and Selecting a Statistics exercises, self-testing questions-answers and exercises using abstracts from real articles. Courses and Journal Clubs can now use Studying a Study and Testing a Test with the help of a special section of the Website. 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 standards for testing the tearing strength of textiles.

Tearing Tester "Elmendorf method" For determinig the Tearing Resistance of Paper and Board. According to the standards: ISO - DIN EN ISO UNE - ASTM D - ASTM D - TAPPI T - DIN EN ISO UNE Thwing-Albert Instrument Company offers a complete line of tensile testers, materials testing machines and instruments for a variety of industries including paper, pulp, . Tear testing provides information on the energy or force required to propagate a tear through a material. Tearing tests are commonly performed on foils, plastics, paper, and textiles. DDL has capability to perform many different types of tear tests, such as trouser tear, graves tear and the pendulum (Elmendorf) method. The most common testing machines are universal testers, which test ma-terials in tension, compression, or bending. Their primary function is to create the stress-strain curve described in the following section in this chapter. Testing machines are eitherelectromechanical or hydraulic. The principal difference is the method by which the load is.
