What is the EN 10219?

 

EN 10219 this European Standard specifies the technical delivery conditions 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.
 
EN 10219 is identical to BS EN 10219, except that it applies to different countries. All of the following requirements are also applicable to BS EN 10219.

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.
 
NOTE: For SAW hollow sections above 508 mm outside diameter it may be necessary to perform a warm shaping operation, which does not affect the mechanical properties, in order to meet the out-of-roundness tolerance requirements.
