EN 1090-1: Requirements for conformity assessment for structural components (CE marking)
EN 1090-2: Technical requirements for the execution of steel structures
EN 1090-3: Technical requirements for the execution of aluminium structures.
Since July 2014 all manufacturers must be certified to EN 1090 by an accredited body – also known as a notified body – and only structural steel and aluminium components with the corresponding CE marking may be sold in or supplied into Europe.
So which requirements apply to you?
EN 1090 has defined four execution classes (EXE). These classes define specific fabrication requirements, with complexity increasing as the numbers rise. The classification procedure is determined by the load-bearing capacity, material and fabrication procedure of the component or structure you manufacture. This is linked to the consequences of failure and degree of fabrication complexity. Once you have been assigned to an execution class, you are only certified to fabricate the items covered in that class.
