The EUROCODES are a group of European Standards for the building industry whose formulation was initiated by the Commission of the European Union in the mid 1970's.
Article 100 of the Treaties of Rome of 1957 and the Single European Act of 1987 obliged member states to take measures for the realisation of the single European market. Goals were the removal of technical barriers to trade, based on the nationally diverging guidelines and usages, and the harmonisation of procurement.
For a period of fifteen years the Commission of the European Union headed the development of the EUROCODES with the aid of a steering commission consisting of delegates of the member states.
The first generation
In 1990 the Commission of the European Union, the member states of the EU and EFTA decided, based on an agreement between the Commission of the European Union and the european standards organisation (CEN), to mandate the formulation and publication of the EUROCODES to CEN to provide for the future status of European Standards.
This connects the EUROCODES with all council directives and/or decisions of the Commission dealing with European Standards.
For the preparation of the EUROCODES the technical committee CEN/TC 250 "Structural Eurocodes" was established, the secretariat of which is held by the British Standards Institute (BSI). For each of the ten parts a subcommittee was set up (e.g. CEN/TC 250/SC 2 „Concrete Structures“).
The first generation of EUROCODES was published in 62 parts from the mid 1990's as European Pre-standard (ENV), in Austria as ÖNORM ENV, to gain experience with the - in part - fundamentally new contents.
These ENV were recommended for application.
From Pre-standard (ENV) to Standard (EN)
Based on the practical experience made with the ENV, at the end of the 1990's, again in CEN/TC 250, the conversion, that is revision, of the EUROCODES commenced. The result of those activities are EUROCODES which will be published as European Standards (EN), in Austria as ÖNORM EN.
The first parts were published in 2003. All 58 parts were available in 2008.
The application of the EN is mandatory.
After implementing all EUROCODES in the national body of standards a transitional period of several years begins. In this period national standards may continue to exist even if their content is contradictory to the one of the EUROCODES. By the end of the transitional period at the latest contradictory standards have to have been revised or withdrawn or new standards to support the implementation of the EUROCODES in Austria have to be completed.

Implementation of the EUROCODES in Austria
As a guideline for the implementation of the EUROCODES the group of „EUROCODE National Correspondents (ENC)“ drafted „Guidance Paper L“. The ENC group was set up by the European Commission and is composed by delegates of national authorities.
Relevance of the EUROCODES – Standards and Legislation
As a member of the European Committee for Standardization CEN , Austria is obliged to implement European Standards in the national body of standards.
European Standards also serve the implementation of directives of the European Commission. Those directives have to be transformed into national law.
This means that with the help of standards laws are specified in detail.
Technical changes based on the EUROCODES
The most significant change concerns the adoption of the semi-probabilistic safety concept.
