Elmendorf Tearing Strength is defined in 2011, which means the ratio of the force required to extend the incised specimen to a specified length under specified load conditions and the thickness of the specimen.
Elmendorf-type tear tester uses a falling pendulum as load force to tear the incision of the specimen to the certain length, thus to determine its tear resistance.
Falling-pendulum can be loaded with differant weight in accordance to the specific range of the specimen, respectively 16N, 32N, 64N, 128N, 300N.
