This fixture is
used to test the tensile characteristics of paper products
after a short soaking period to aid in avoiding the
difficulties encountered when testing wet test specimens
having very low strength. The fixture consists of a rigid
inverted metal stirrup with a horizontal rod. Located
between the metal stirrups is a small, easily removable
reservoir for holding water.
Spring clips hold the reservoir in position and permit the
reservoir to be repositioned. A metal tongue at the bottom
of the fixture is used to securely fasten the fixture to the
test machine.
Packaging
Includes
fixture only. Grip is not included and must be ordered
separately.
Applications
Used
for loop tensile testing of wet paper or board products. Wet
tensile strength is defined as the maximum force that a test
specimen will withstand, after soaking in water, before it
breaks under specified conditions. Wet strength retention is
defined as the ratio of the value of the tensile strength of
a paper or board in the wet state to that of the same
specimen in the dry state, under specified conditions. |
