European Union (CEN) standards[edit]
The European Committee for Standardization (CEN) had issued numerous standards covering
welding processes, which unified and replaced former national standards. Of the former national
standards, those issued by BSI and DIN were widely used outside their countries of origin. After
the Vienna Agreement with ISO, CEN has replaced most of them with equivalent ISO standards (EN
ISO series).[7]
