This European Standard specifies requirements for extruded products (rod/bar, tube, profiles) which contribute to the structural properties of the railcar bodyshell and other major structural components. The requirements on welded joints specified in this standard are not applicable to welded assemblies and sub-assemblies as they are specified for material qualification purposes only. It specifies particular requirements regarding qualification, quality control, material properties and dimensional tolerances. Furthermore, guidelines for application and use are also given. NOTE Some of the products listed in the present standard can be subject to patent or patent applications, and their listing herein does not in any way imply the granting of a licence under such patent right. CEN/TC 132 affirms that it is its policy that in the case when a patentee refuses to grant licenses on standardised standard products under reasonable and not discriminatory conditions, then this product is removed from the corresponding standard.
