DIN EN 14294
Adhesives for leather and footwear materials - Preparation of bonded test pieces by moulding-on processes; German version EN 14294:2010
Klebstoffe für Leder und Schuhwerkstoffe - Herstellung von Verbund-Proben nach dem Anformverfahren; Deutsche Fassung EN 14294:2010
Overview
This draft standard specifies procedures for the preparation of test pieces comprising adhesive coated leather or other footwear upper material onto which a soling material is moulded directly. The procedures described simulate direct vulcanising of rubber, injection moulding of thermoplastics and reaction moulding of polyurethane. The prepared test pieces are suitable for the test procedures described in DIN EN 1392 and to meet the requirements of DIN EN 15307. The surface of the leather, other footwear upper material or other footwear component material used is treated in a manner specific to the nature of the material. Strips of specified length and width are cut from the treated material. One or more of these strips are coated with adhesive and attached, with the bonding surface uppermost, to the bottom plate of a mould. Soling material is introduced to fill the mould and allowed to cure or set as appropriate to produce an assembly of soling bonded to upper material. The moulded assembly, and test pieces cut from it, are stored under specified conditions before testing. The test standard addresses the shoe manufacturers and independent test institutes. At DIN the Committee responsible for this standard is NA 062-04-52 "Schuhe" ("Footwear").
