TAPPI T414 Elmendof Tearing Tester for Internal Tearing Resistance Test of Paper
A pendulum impact tester is used to measure the force required to propagate an existing slit a fixed distance to the edge of the test sample. One use of these results would be for the specification of material and thickness for plastic film used in packaging. Depending upon the application, a low propagation force or a high propagation force might be more desirable.
Ten samples each are cut from the plastic film in the machine direction and in the transverse direction. A sample is positioned in the tester and clamped in place. A cutting knife in the tester is used to create a slit in the sample which ends 43mm from the far edge of the sample. The pendulum is released to propagate the slit through the remaining 43mm. The energy loss by the pendulum is used to calculate an average tearing force.

Test results are presented as tearing force in milli-newtons (or grams-force). Sample thickness is also reported, although there is no direct relationship between thickness and the tearing force. Therefore only results for samples of the same thickness can be compared.
