Incline plane coefficient of friction tester measures the static coefficient of friction of various materials using a variable inclined plane and a sliding block. It measures the static COF of plastic films, sheets, rubber, paper, board, woven , fabrics, wood, coatings, brake pads, etc.
Principle: The static COF is measured by the angle at which one test surface begins to slide against another inclined surface as the incline is increased at a constant and preset rate. The test result is numerically equivalent to the tangent of that angle.
