This European Standard shall be given the status of a national standard, either by publication of an i
17、dentical text or by endorsement, at the latest by April 2014, and conflicting national standards shall be withdrawn at the latest by April 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held
18、responsible for identifying any or all such patent rights. This document supersedes EN 10269:1999 and EN 10269:1999/A1:2006. For a list of significant changes that have been made in this new version, see Annex E. This document has been prepared under a mandate given to CEN by the European Commission
19、 and the European Free Trade Association, and supports essential requirements of EU Directive 97/23/EC. For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. NOTE The clauses marked with a point () contain information relating to agreement
20、s which are to be made at the time of enquiry and order. The clauses marked by two points () contain information relating to agreements that may be made at the time of enquiry and order. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countrie

BS EN 10269:2013EN 10269:2013 (E) 5 1 Scope This European Standard specifies requirements for semi-finished products, bars and rods for fasteners with properties specified at elevated and/or low tempe
23、ratures made of non-alloy and alloy (including stainless) steels and nickel alloys as given in Table 1. The requirements of this standard may be applied also to the finished fasteners. The general technical delivery conditions in EN 10021 also apply to products supplied in accordance with this Europ
24、ean Standard. NOTE Once this European Standard is published in the EU Official Journal (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this European Standard and does not presume
25、 adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 97/23/EC are satisfied, needs to be done. 2 Normative
