European Standard (EN) 

The  European Standard (EN) is CEN's prime deliverable by excellence.
An EN is the result of a transparent, open and consensual development process with national commitment. The individual steps of this process are accessible via the index on the left, where they appear in chronological order.

European Standards shall be implemented at national level in all CEN member countries by being given the status of national standards and any conflicting national standard shall be withdrawn.
