The range of Tearing Strength Testers is widely used for the purpose of determining the ballistic tearing strength of different types of material like papers or boards and textiles with suitable pendulum. These testers are made available to the clients in varied specifications to meet the clients' requirements in an efficient manner. We also customise these testers as per the exact details specified by the customers.

Following are the technical specifications of these products:

These testers determine the tearing strength of fabrics, papers, plastic films or other similar material
Testing is done by measurement of the work done in tearing through a fixed length of the test specimen using of Elmendorf Tear Testers
The Elmendorf Tearing Strength Testers consist a brass sector pendulum pivoted on anti-friction ball bearings on a vertical bracket fixed on a rigid metallic base
Test specimen in shape of a rectangular piece is held between two clamps, one of which is mounted on the pendulum and the other is mounted on the vertical bracket
Clamps are mounted in such a manner that their holding faces are aligned with each other when the pendulum is locked in its raised position
The pendulum is released by lifting a release lever
This action causes the test specimen to tear right through
The tearing strength is indicated on a scale fitted on the pendulum against a low friction pointer pivoted on the axis of the pendulum
An adjustable knife is also mounted on the bracket on which the pendulum and the fixed clamp is mounted
It is centred between the two clamps and is used for making the initial cut in the test specimen
The apparatus is finished in metallic painting and bright chrome plating to give it corrosion resistant finish
Augmenting weights for increasing the range of the tester for testing high strength material are available as optional accessories
Low strength material can be tested by mounting multiple specimens at the same time
