RS-T08 Elmendorf Tearing Tester
The tearing strength of fabrics, papers, plastic films, or other similar materials is determined by measurement of the work done in tearing through a fixed length of the test specimen using Elemendorf Tear Tester.
The Elemendorf Tear Tester consists of a brass sector pendulum pivoted on anti-friction ball bearings on a vertical bracket fixed on a rigid metallic base. The test specimen is in shape of a rectangle and is held between two clamps, one of which is mounted on the 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 the pendulum is locked in its raised position. The pendulum is released by lifting the 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 same axis as the pendulum.
An adjustable knife is mounted on the bracket on which the pendulum and the fixed clamp is mounted. The blade is located between the two clamps and is used for making the initial slit in the test specimen. A brass check weight is supplied with the
tester for verification of its calibration. The apparatus is finished in blackmalt finish and
bright chrome plating to give it a corrosion resistant finish.
Augmenting weights for increasing the capacity of the tester are available as optional
accessories. For testing of low strength materials, multiple specimens may be mounted
at the same time. Weight:15kg
