Elemendorf Tear 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.
