3、11 October 2002 Addition of Annex ZA This British Standard is the English language version of EN 10222-1:1998, including amendment A1:2002, published by the European Committee for Standardization (CEN). Together with EN 10222-2 to -4 it supersedes BS 1503:1989 which will be withdrawn when the four p
4、arts of EN 10222 are published. The UK participation in its preparation was entrusted by Technical Committee ISE/73, Steels for pressure purposes, to Subcommittee ISE/73/3, Steel forgings for pressure purposes, which has the responsibility to: - aid enquirers to understand the text; - present to the
5、 responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; - monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request
6、to its secretary.
