Elmendorf Tearing Tester For Testing Lab Workshop.
Elmendorf Tearing Tester - For Testing Lab
The tearing strength of fabrics, papers, plastic films, 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 .
TheElmendorf Tearing Tester
consists of a brass sector pendulum pivoted on low-friction ball
bearings over a vertical bracket fixed on a rigid metallic base. The
test specimen, in shape of a rectangle, 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 a release
lever. This action causes the pendulum to fall down under its weight and
to tear the test specimen while doing so. The energy absorbed during
tearing is indicated on a scale fitted on the pendulum by a low friction
pointer pivoted on the axis of the pendulum
