Elmendorf Tearing Tester

Overview

Elmendorf tearing tester is designed to measure average tearing force of materials from the energy loss of a falling pendulum. By well simulating the practical case, a test specimen is exposed to a sudden heavy load which causes the test specimen to tear, propagating an existing cut, such as a seam or a button hole. Start from a single tongue-type cut in sample and measure tearing strength from the energy loss of a falling pendulum while the cut propagating, the testing result is considered usable only when in 20 – 80 % of each full scale range, or else next weight should replace. It is designed to determine tearing force of fabric, non-woven, paper, cardboard, plastic film, etc. Providing solid results for QC, material R&D, Certification & Testing.
