32、ootwear manufacture or repair and have adequate wear properties as upper or sole materials 4 Principle The surfaces of the leathers or the footwear materials used are treated by a method specific to the type of material. Then strips of specified length and width are cut from the treated materials. T

33、he treated surfaces are bonded by an adhesive to test pieces of specified form. The test pieces are stored under specified conditions and their bond strength is determined under specified conditions.
