Responsibilities and time schedule
The implementation of an EN Eurocode part has three phases, the Translation Period, the National Calibration Period and the Coexistence period. The periods are relative to the date where the CEN has delivered the EN Eurocodes Part to the National Standardisation Body (Date of Availability DAV). The Eurocodes are implemented in the EU Member States. The information is intended as assistance to other countries that wish to implement the Eurocodes.
The National Standardisation Body (NSB) may start the translation of a Eurocode Part
in authorised national languages at the latest at the DAV. The maximum time
allowed for translation is 12 months after DAV.
National calibration period
The Member State should fix the Nationally Determined Parameters
within a period of two years after DAV at maximum. At the end of this period,
the national version of an EN Eurocode Part will be published by the NSB, with
the National Annex. The Annex will include the Nationally Determined Parameters
and reference to Non-Contradictory Complementary Information (NCCI).
At the end of this period, the Member State should have adapted their
National Provisions so that the Eurocode Part can be used on its territory. The
Member State shall inform the Commission about the result of the tests
undertaken using the EN Eurocode Part.
During the coexistence period, which starts at the end of the
National Calibration period, the Eurocode Part can be used, just as the former
national system can also be used. The coexistence period of a Eurocode Package
will last up to a maximum time of three years after the national publication of
the last Part of a Package.
The coexistence period of a Package is terminated when the NSBs have
withdrawn all conflicting national standards, and the Member States shall make
sure that all the Parts of the related Package can be used without ambiguity on
their territories by adapting their National Provisions as necessary. Thus all
conflicting National Standards in a package should be withdrawn a maximum of 5
years after DAV of the last available standard in the package.
