Ideal for
specimines as small as 2mm (3/32 in) in diameter, this
miniature wedge grip features hardened steel, serrated jaw
faces. Throat depth is 12mm (0.5 in). A spring force lever
permits quick release of the jaw face for simple loading or
removing of the specimen.
Packaging
Includes
fixture, clamping device and sled.
Applications
Used
to determine the static and kinetic coefficients of friction
of plastic film and paper when sliding over itself under
controlled test conditions. A sheet of the specimen is
clamped securely to a horizontal bed and another sample is
clamped to the underside of a sled. The force required to
overcome the frictional resistance between the two imposed
surfaces, when one is moved relative to the other along
their plane of contact, is measured. The static coefficient
of friction is determined by the force required to overcome
the initial resistance between the two surfaces. The kinetic
coefficient of friction is determined from the subsequent
force when continuous sliding at a constant rate of movement
is sustained. |
