18、ent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. With respect the previous version of EN 15307, the following main changes have been made: 1. In order to clarify, the test in 5.2.1 has been reworded as follows: “The peel resistance after 4 d

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.

34、dance with practical experience gained the different types of footwear can be classified with regard to the mechanical stress on its sole-upper bonds in use as follows: Class A: Low stress on sole-upper bonds in use (i.e. infants footwear, indoor footwear, fashion footwear) Class B: Medium stress on
35、 sole-upper bonds in use (i.e. men town footwear, women town footwear, cold weather footwear and casual footwear) Class C: High stress on sole-upper bonds in use (i.e. children footwear and general sports footwear) Class D: Very high stress on sole-upper bonds in use (i.e. mountain footwear) 5.2 Spe
