An Elmendorf tear test measures how resistant a material is to the continuation of a tear once it has started. A specimen is prepared with a small slit, clamped into the instrument, and then struck by a pendulum. The pendulum swings through the sample, and the energy it uses to extend the tear is recorded as the tearing strength.

This method is widely used for paper, plastic films, textiles, and nonwovens because it simulates real situations where a small cut or damage can grow under stress. By capturing the force needed to propagate the tear, the test helps manufacturers and labs compare material grades, check product durability, and confirm compliance with international standards.
