Static & Kinetic Friction Tester as per ASTM D-1894, with an Inclined Plane Tester model as per TAPPI T-815.
The Coefficient of Friction Tester (C.O.F Tester) determines the static and kinetic coefficients of friction of plastic films and sheeting, as per ASTM D-1894. The coefficient of friction describes how easily two surfaces slide over each other — a property that directly affects how film unwinds, feeds, stacks and runs on packaging, printing and converting machinery. Too much friction causes jamming; too little causes slipping and unstable stacks.
In the standard test, a sled of known weight rests on the film and is pulled at a controlled speed while the machine records the force needed to start and to maintain motion, giving the static and kinetic friction values. A Computerised model adds a microcontroller with RS-232 communication and PC interface software for a Load vs Travel graph, result storage and printout, and merging of up to 10 samples with mean and standard deviation. International Equipments also offers an Inclined Plane Tester model as per TAPPI T-815 for friction between film to film, film to metal and film to glass.
