Elmendorf tear testing uses a pendulum that swings through a pre-cut specimen, and the energy needed to propagate the tear is recorded. It is quick, simple, and ideal for paper, films, and woven fabrics where a sharp tear event is expected.

Trapezoid and trouser tear methods, on the other hand, are performed on a tensile testing machine in a constant-rate-of-extension (CRE) setup. Instead of a pendulum, the sample is pulled apart steadily, and the tearing force is measured throughout the test. These methods are better suited for flexible, elastic, or knitted materials where controlled loading provides more meaningful data.
