The Tearing Strength of fabrics, Paper, Plastic Film, or other similar materials in sheet form is determined by measurement of work done in tearing through a fixed length of the test specimen using the Elmendorf tear tester.

The Elmendorf Tear Tester consists of a brass sector pendulum pivoted on anti friction ball bearings over a vertical bracket fixed on a rigid metallic base. The test specimen, in shape of a rectangular, is held between two clamps, one of which is mounted on a pendulum and the other is mounted on the vertical bracket. The clamps are mounted in such a manner that their holding faces are aligned with each other when pendulum is released by lifting a release lever the action cause the pendulum to fall down under its weight & to tear the test specimen while doing so. The energy absorbed during tearing is indicated on a scale fitted on pendulum by a low friction pointer pivoted on the axis of the pendulum.

An adjustable knife is also mounted on the pendulum upper bracket is centered between the two clamps & is used for making the initial slit in the test specimen.

A check weight is supplied with the tester for verification of the scale.

The instruments is finished is metallic painting and bright chrome plating to give it a corrosion resistant finish.
