本欧洲标准规定了有助于轨道车身壳体和其他主要结构部件的结构性能的挤出产品（棒/棒，管，型材）的要求。 本标准规定的焊接接头的要求不适用于焊接组件和子组件，因为它们仅用于材料鉴定目的。 它规定了关于质量，质量控制，材料性能和尺寸公差的特殊要求。还提供了应用和使用指南。 注意本标准中列出的某些产品可能受专利或专利申请的约束，其上市并不意味着根据该专利权授予许可证。 CEN/TC 132申明，如果专利权人拒绝在合理而不歧视的条件下拒绝对标准化标准产品发放许可证，则该产品将从相应的标准中删除

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. 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.
