19、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 and dispersion adhesives, under different conditions. These can be chosen taking into account the different stresses that such bonds a
20、re subjected to, depending on the type of footwear. 2 Normative references The following referenced documents are indispensable for the application of this document.
