EN 10025 Steel Explanation

EN 10025 : 2004 is the new European standard for structural steel. 

The Comité Européen de Normalisation (CEN) (European Committee for Standardisation) is an association of the national standards organizations of 18 countries of the European Union and of the European Free Trade Association. The principal task of CEN is to prepare and issue European Standards (EN), defined as a set of technical specifications established and approved in collaboration with the parties concerned in the various member countries of CEN.

The identification of European standards in each member country begins with the reference letters of the country’s national standards body, for example, BS for BSI in the United Kingdom, DIN for DIN in Germany, NF for AFNOR in France, etc., followed by the initials EN and a sequential number of up to five digits, for example, BS EN 10025, DIN EN 10025, or NF EN 10025 are all the same standard.

One example of one specification is below:
