This European Standard shall be gi

    14、ven the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2015, and conflicting national standards shall be withdrawn at the latest by June 2015. This document supersedes EN 15307:2007. Attention is drawn to the possibility that some o

    15、f the elements of this document may be the subject of patent 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

    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

    20、t purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory conditions. ENVIRONMENTAL STATEMENT It is understood that some of the material perm

    21、itted in this standard may have negative environmental impact. As technological advantages lead to acceptable alternatives for these materials, they will be eliminated from this standard to the extent possible. At the end of the test, the user of the standard should take care to carry out an appropr

    46、 of the leather or footwear material used according to 6.2; d) complete identification of the adhesive used for the preparation of the test pieces according to 6.3; e) preparation of the bonding surfaces of the leather or footwear material according to EN 1392; f) complete identification of the bond

    47、ing procedure according to EN 1392 (adhesive applicator, number of adhesive coats applied, length of intermediate drying periods, contact or heat activated bonding, activation temperature of the adhesive coats etc.); g) description of the conditions of storage of the test pieces; h) test results, in

    48、dividual and mean values according to EN 1392 and mode of failure according to EN ISO 10365; i) factors which may have affected the results; j) date of test. BS EN 15307:2014EN 15307:2014 (E) 9 Annex A (informative) Reference test adhesives and reference test materials In the footwear industry a lar

    49、ge number of different solvent or dispersion adhesives are applied for sole-upper bonding offering a broad range of technical effects. The most important and most often adhesives used are based on polyurethane and polychloroprene. For research, development and quality certification purposes some simply formulated 1- and 2-part test adhesives have been developed which can be considered as typical adhesives of these types (information from national footwear institutes), e.g.: Reference Test adhesive CR 1: One part polychloroprene
