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all CEN member countries by being given the status of national standards and any conflicting national standard shall be withdrawn.
* Note: 'Primary and Updating Questionnaire' is an alternative to 'Drafting of European Standards up to Enquiry stage', up to and including 'CEN Enquiry', which can be applied to adopt a Reference Document (e.g. an available ISO standard) as a European Standard
