Taber Multi-Finger Scratch / Mar Tester is used to evaluate the scratch and mar resistance of resilient materials. A variable speed, pneumatically driven sledge is moved below five independent, weighted scratch "fingers" that are equipped with interchangeable scratch tips.
The design of Multi-Finger Scratch / Mar Tester is based on the apparatus described in automotive specifications (including Ford BN 108-13; General Motors GMN3943; Daimler-Chrysler LP-463DD-18-01 & PF-10938; and Nissan NEW M0159 Supplement U01-1), which is commonly referred to as a five-finger (five-arm) scratch & mar tester.
The Multifunctional Scratch Resistant Instrument includes a pneumatically driven, moveable sledge to which the test sample is mounted. The sledge moves in a linear fashion, and is operated by a control knob for one or multiple pass testing. An electronic timer displays the rate of speed, which can be controlled by reducing or increasing air pressure.
A gantry supports five independent splined-fingers, which provide a constant, vertical load on interchangeable scratch pins (1.0mm or 7.0mm diameter hemisphere). The gantry system includes a handle to raise and lower the arms. In addition, five support rests are incorporated to allow one or more arms to be moved to an upright, rest position such that the arm does not contact the specimen during testing.Individual weights of varying loads mount to the top of each arm finger to exert a standard force on the surface of the test material.
