This European Standard specifies the technical delivery conditions for welded cold sized steel tubes of circular cross section for precision applications with specified outside diameter D ? 193,7 mm. This document may also be applied to other types (excluding square and rectangular) of cross section. Tubes according to this document are characterized by having precisely defined tolerances on dimensions and a specified maximum surface roughness. Typical fields of application are in the vehicle, furniture and general engineering industries.
