and BS EN 10263-4:2001 it supersedes BS 3111-1:1987, which is UK participation in its preparation was entrusted to Technical Committee
ISE/71, Steel rods for wire drawing, which has the responsibility to:
——aid enquirers to understand the text;present to the 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 to its -referencesThe British Standards which implement international or European
publications referred to in this document may be found in the BSI Standards
Catalogue under the section entitled “International Standards Correspondence
Index”, or by using the “Find” facility of the BSI Standards Electronic
Catalogue.A British Standard does not purport to include all the necessary provisions of
a contract. Users of British Standards are responsible for their correct
