Coefficient of Sliding Friction Fixture These fixtures consist of a horizontal flat bed
incorporating a suitable clamping device and a sled. The
underside of the sled has a layer of smooth-faced foam
rubber. >
The TG19 fixture is for LF PLUS and TA PLUS Series testers only.The TG35 fixture is for all bench-type LLOYDINSTRUMENTSmaterial testers. Not for use with LF PLUS and TA PLUS Series.

Applications

Used to determine the static and kinetic coefficients of friction of plastic film and paper when sliding the
specimen over itself under controlled test conditions. A sheet of the specimen is clamped securely to the
horizontal bed and another sample of the specimen is clamped to the underside of the sled. This measures the force required to overcome thefrictional resistance between the two imposed surfaces,
when one surface is moved relative to the other along
their plane of contact. 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 continuously sliding at a constant rate. >

Standards Applicable

NEXYGENЙ MT Software (p/n 40/0658) isrequired to measure coefficients of friction to
conform to the following standards: ASTM D1894,
BS2782. >
Note: See Grip Adapter Section (Page 105) foradapters required to fit force gauges, loadcells and test
stands.
