NBN EN 10162:2003

This European Standard specifies dimensional and cross-sectional tolerances for cold rolled steel sections produced on roll-forming machines.
It applies to cold-rolled sections for general use (standard sections) produced from steels conforming to EN 10025, EN 10142 and EN 10147 and in the form of rectangular L, U, C, Z and Omega cross sections as well as split tubes (see Figures 1 to 6).
It also applies to cold rolled sections for special applications (special sections) produced from steels listed in clause 5 with other radii, tolerances and shapes.
NOTE Examples of special sections are sections for steel-framed buildings, door frames and sections for rolling stock, automobiles and bridge engineering (see Figures 7 and 8).
This European Standard does not apply to drawn, pressed or folded cold formed sections, cold rolled steel piling or sections manufactured on the basis of special standards.
