21、ethods to measure 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 are subjected to, depending on the ty
22、pe of footwear, under different external conditions in service. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications.
