Its physical meaning can be understood as the resistance of the film surface to the action of the other hardness of the larger objects. It can be determined by measuring the ability of the film to resist deformation when a certain mass load is exposed on the surface of the film, (including the ability of deformation caused by collision, indentation or scratching). the test equipment should have damped pendulum hardness, scratch hardness, indentation hardness ,ect..
