Coefficient of Friction (COF) testing is used for a variety of materials from lubricants, to films and household items (ceramic tiles) to determine the frictional characteristics of a material. . Static friction or coefficient Static friction is the force that holds back a stationary object up to the point that it just starts to move. Thus . The static friction between the two surfaces is higher than the kinetic friction. Static friction is due to the forces of adhesion between surfaces. A large force is required to overcome these adhesive forces. When the applied force is equal to the static friction force, the surfaces will start to move relative to one another.
