8、onal forewordThis British Standard is the UK implementation of EN 10902:2018. It supersedes BS EN 10902:2008+A1:2011, which is withdrawn.BSI, as a member of CEN, is obliged to publish EN 10902:2018 as a British Standard. However, attention is drawn to the fact that during the development of this Eur

9、opean Standard, the UK committee decided to abstain from voting to approve it as a European Standard because it was unable to reach a consensus position.The UK committee has concerns over the lack of clarity between the scope of BS EN 10902:2018 and the scope of the new BS EN 10904, particularly reg

10、arding product forms, material grades, thickness limits and joining processes.Another concern with EN 10902:2018 is its relationship with both BS EN 1990:2002+A1:2005 and the design rules in the BS EN 1993 series, particularly about reliability differentiation and the integrity of welded joints. Alt

11、hough EN 10902:2018 contains sufficient choices to ensure full compatibility with these standards, care must be taken to ensure the correct choices are made. Further information on these choices is given in Clause NA.2.27.3 of the National Annex to BS EN 199311:2005+A1:2014.The UK participation in i

12、ts preparation was entrusted to Technical Committee CB/203, Design 77.150.10Compliance with a British Standard cannot confer immunity from legal obligations.
