EN 1392:2006 (E) 4 1 Scope This European Standard specifies the testing of some strength properties of bonds of leather and footwear materials, in stuck-on assemblies using solvent-based
20、and dispersion adhesives, under different conditions. These can be chosen taking into account the different stresses that such bonds are subjected to, depending on the type of footwear. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、dequate wear properties as upper or soling material 3.3 adhesives for leather and footwear materials adhesives which are intended to produce firm and durable bonds of leather and footwear materials 4 Principle The surface of the leather or the footwear material used is treated specifically to the na
27、ture of the material. Then strips of specified length and width are cut from the treated material. EN 1392:2006 (E) 5 Two of these strips or one strip of the above mentioned material and one strip of a suitable different material are bonded by an adhesive to test pieces of specified form. The test p
28、ieces are stored under specified conditions and their bond strength is determined under specified conditions. 5 Test methods 5.1 Types of tests 5.1.1 Peel tests at (23 2) C See 5.4.2 5.1.2 Peel test under constant load and at a constant elevated temperature (“creep test“) See 5.4.3 5.2 Adhesives and
