Stiffness Tester 112
Flexible Material Stiffness Testing
Measure the flexural rigidity and drape characteristics
of flexible materials.
Stiffness Tester Model 112 employs the principle of
cantilever bending of the specimen under its own mass.
Ideal for testing non-wovens and most fabrics, this tester
conforms to existing test standards. May also be used to
evaluate films, paper, leather and other flexible materials.
Simple to use, rugged design provides repeatable test
results.
The specimen is moved across a smooth low-friction
platform at a constant rate. An optional hand crank provides
an economical solution for controlling test speed. As the
leading edge of the specimen projects from the platform, it
bends under its own mass. The length of the overhang is
measured when the specimen’s leading edge contacts the
indicator. From this measured length, the bending length
and flexural rigidity are calculated.
Rugged design includes numerous features.
An adjustable bend angle indicator can be inclined 41.5°
(0.724 rad) or 45° (0.785 rad) below the plane of the platform
surface, and includes a bend angle reference. The movable
specimen slide includes a leveling bubble and is operated
manually or by an optional precision hand crank. The
overhang scale is calibrated in both metric and English units.
