1 Definitions 1.1 Friction The phenomenon impeding the tangential relative movement between contact surfaces of two objects. 1.2 Friction by sliding The friction generated in the case that the contact points of two contact objects moves at different speeds. 1.3 Friction force The resistance to friction when two objects move toward opposite direction. 1.4 Friction coefficient The ratio of the friction force impeding the relative movement of two objects to the normal force acted on the object surface. 1.5 Wear Continual loss or residual deformation of substances on surfaces of two contact objects in relative movement. 2 Specimen 2.1 Plastic specimen dimension
