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

16、 been reworded as follows: “The peel resistance after 4 d storage in the standard atmosphere 23/50 according to ISO 554 shall be for sole-upper bonds of: Class A: at least 2,5 N/mm; Class B: at least 3,0 N/mm, or at least 2,5 N/mm with material failure; Class C: at least 4,0 N/m or at least 3,0 N/mm

17、 with material failure; Class D: at least 5,0 N/mm or at least 3,5 N/mm with material failure. Definition of “material failure” is included in EN ISO 10365.” 2. In order to clarify 5.2.3, the sentence “(separation distance of the bonding)” has been added before the comma. 3. In order to clarify, the

18、 test in 6.5 has been reworded as follows: “Before starting peel tests specified in 6.1 store the test pieces in the standard atmosphere of 23/50 according to ISO 554 for 4 d in case of test described in (5.2.1), for 2 min in case of test described in (5.2.2) and before warming up to (50 2) C for 6

19、d in case of test described in (5.2.3).” 4. In Annex A, the full name of the abbreviations NBR, SBR, SBSR and PVC have been added between parentheses in the test. SAFETY STATEMENT Persons using this document should be familiar with the normal laboratory practice, if applicable. This document does no

29、nd synthetic materials which are suitable for footwear 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

30、and width are cut from the treated materials. The 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. BS EN 15307:2014EN 15307:2014 (E) 6 5 Minimum strengt
