EN 10305-3 specifies the technical delivery conditions for welded cold sized steel tubes of circular cross section for precision applications. It can also be applicable to non-circular (excluding square and rectangular) cross sections. Tubes according to EN 10305-3 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.

Manufacture: the tubes shall be manufactured from steel strip by electric welding. The tubes shall not include welds used for joining lengths of flat rolled strip prior to forming the tube, except for coiled tubes which may be supplied in the delivery conditions +A and +N. Surface conditions: S1 (black); S2 (pickled); S3 (cold rolled); S4 (coated to an agreed condition). The surface conditions S1 and S3 apply for the strip. The surface condition S2 and S4 may apply for the strip or the tube.
Delivery Condition: tubes made of the steel grades E155, E195, E235, E275 and E355 shall be supplied in the delivery condition +CR1 or +A or +N; tubes made of the grades E190, E220, E260, E320, E370, E420 and S500MC shall be supplied in the delivery condition +CR2.
Inspection & Test: chemistry composition analysis, tensile test, flattening test, flaring test, NDT, surface inspection and dimension check.
