This document (EN 1990:2002) has been prepared by Technical Committee CEN/TC 250 «Struc-tural Eurocodes», the secretariat of which is held by BSI. The Eurocodes, as far as they concern the construction works themselves, have a direct relationship with the Interpretativ Documents referred to in Article 12 of CPD, although they are of a different nature from harmonized product standards. Therefore, technical aspects arising from the Eurocodes work need to be adequately considered by CEN Technical Committees and/or EOTA Working Groups working on product standards with a view to achieving a full compatibility of these technical specifications with the Eurocodes. The Eurocodes standards provide common structural design rules for everyday use for the design of whole structures and component products of design conditions are not specifically covered and additional expert consideration will be required by the designer in such cases.
