The creation of the EEC (European Economic Community) has made it necessary to establish common standards named "European Norms" (EN), therefore standardizing the common language across Europe. Since 1988 a new series of 'mandatory' European standards (EN) has been created, to replace national standards, such as BS, DIN, SS and NF, throughout 18 countries of Western Europe.
The EN Designation System uses an alpha-numerical index to denote the key information about the material including mechanical properties, tensile strength and potential usage.
For more information on the EN designation system see Introduction to the Euronorm Standard Designation System.
