The first generation of EN Eurocodes was published between 2002 and 2007, with conflicting British Standards withdrawn in 2010. This National Annex forms part of the second generation of EN Eurocodes suite of documents. The second generation of National Annexes to Eurocodes are expected to be published between 2024 and 2026. These documents are being published as soon as they are available. This is being done to enable users to prepare for the transition from the first generation to second generation of EN Eurocodes suite of documents. National Annexes of the first generation of Eurocodes will be withdrawn alongside the first generation of EN Eurocodes by BSI on 30 March 2028.
