Steel tubes for precision applications - Technical delivery conditions - Part 3: Welded cold sized tubes

This Part of this European Standard specifies the technical delivery conditions for welded cold sized steel tubes of circular cross section for precision applications. NOTE This Part of this European Standard may also be applicable to non-circular (excluding square and rectangular) cross sections. Tubes according to this Part of this European Standard are characterized by having precisely defined tolerances on dimensions and a specified surface roughness. Typical fields of application are in the vehicle, furniture and general engineering industries.
