Elmendorf Tear Tester Internal Tear Tester Mechanical

Elmendorf Tear Tester Operation

Simply place the sample in the two clamps and tighten, use the inbuilt knife to make the initial tear, release the pendulum. The tearing resistance of the material is measured via the transference of the potential energy stored in the raised pendulum to kinetic energy. A portion of this energy is absorbed during the tearing of the sample and is used as a measure of the materials resistance to a continuing tear. The energy required to tear the sample is reported as a percentage of the pendulum capacity or force in mN or gf.
