EN 10219-1 and EN 10219-2 specify the technical delivery conditions, tolerances, dimensions and sectional properties for cold formed welded structural hollow sections of circular, square or rectangular forms and applies to structural hollow sections formed cold without subsequent heat treatment.

Manufacture: hollow sections to EN 10219-1 and EN 10219-2 shall be manufactured by electric welding (ERW) or submerged arc welding (SAW).
Delivery Condition: the hollow sections shall be delivered cold formed without subsequent heat treatment except that the weld seam may be in the as welded or heat treated condition.
Inspection & Test: chemistry composition analysis, tensile test, impact test for qualities J2 and K2, welded pipes NDT of the weld, surface inspection and dimension check.
