The test is performed using a pendulum impact tester, which .Elmendorf Tear Tester: An Essential Tool. The Elmendorf tear tester is widely recognized for its accuracy and reliability in measuring tearing resistance. This instrument operates by tearing a sample through a fixed distance using a pendulum mechanism, allowing for precise measurement of the force required to propagate a tear. According to this model, the tear test of film is a special case of a high-speed stress/strain measurement performed on a polymer sample with a varying cross-section. The tear resistance of film is a function of all the parameters that characterize the stress/strain curve of the resin: stresses and strains at the yield, the necking, and the .
