Manually Operated Incline Plane COF Tester

Home » Manually Operated Incline Plane COF Tester

This instrument is used to determine the coefficient of static friction of most packaging materials by measuring the angle at which one test surface begins to slide against another inclined surface as the incline is increased at a constant and prescribed rate.  As the plane rises, the first sign of movement from the sled is detected by the operator and a recording of the relevant angle of the incline is noted.  The test is frequently referred to as a slide angle.  The coefficient of friction is numerically equivalent to the tangent of that angle.
