Equipment type: Coefficient
of Friction Tester
Manufacturer / Brand: RDM
Scope of usage: The CF800 Coefficient of
Friction Tester is designed to determine the coefficient of friction properties
of plastic films, laminates, foils and papers. The apparatus conforms primarily
to the BS2782 method 824A and ASTM D 1894-78, but it can be supplied to suit
other international test methods.
The tester is connected to a PC what enables data storage and further analysis in certain
Examples of application for polymer
analysis / information that can be obtained by this method for polymers: Determination of static and dynamic friction coefficient between
two polymer surfaces or between polymer surface and some other material
Measurement range: Maximum load, as a consequence of friction is
limited to 1500g.
Sample limitations: For standard measurements we need a part of sample
sized 12cm x 6.3cm, which is clamped on sleed and another part sized 60cm x 16cm,
clamped on grounding. For measurements which are not made by standards,
mentioned above, we need samples with area few cm2.
Limitation of application conditions: Friction tester is operating on room temperature on air.
Tester RDM CF800 XS.
One part of sample is
clamped on sleed (left) and another part is clamped on grounding. Sleed is trailed
on the grounding by measuring cell, which measures friction between moving
sample on sleed and static sample on grounding.
A touch-screen panel is
user friendly and displays current values of friction during measurement.
