Product Standards
The European harmonised standards provide a direct presumption of
conformity to the corresponding Directives essential requirements.
The European non harmonised standards, are however an agreed tool that
can assure transparency and common understanding; consequently they are
becoming a more and more applied reference in manufacturing contracts.

Welding of railway vehicles and components |
The most important applicable European standards, dealing with
welding fabrication, are shown in the table.
All these standards, when facing the welding fabrication process
control, mention directly or indirectly the EN ISO 3834, and consequently
certification of personnel.
The implementation of these directives and product standards that has
been implemented in the European countries in the last 10 years, will
dramatically increase the needs for certified welders as well as the
regular maintenance of their certificates. The inclusion of the new member
states, which now have to cope with the above directives and standards,
will further create strain on the education systems.
