This European Standard shall be given the status of a national standard, ei
18、ther by publication of an identical text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by October 2009. This document includes Amendment 1, approved by CEN on 2009-03-14. This document supersedes !EN 10028-1:2007“. The start and
19、 finish of text introduced or altered by amendment is indicated in the text by tags !“. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 97/23/EC. For relationship with
20、 EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. EN 10028 consists of the following parts under the general title Flat products made of steels for pressure purposes: Part 1: General requirements Part 2: Non-alloy and alloy steels with specified elevated t

BS EN 10028-1:2007+A1:2009EN 10028-1:2007+A1:2009 (E) 4 1 Scope This European Standard specifies general technical delivery conditions for flat products for the construction of pressure equip
25、ment. The general technical delivery conditions in EN 10021 also apply. 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 o
26、f materials in this European Standard (Part 1 and the other relevant part of the series) and does not presume 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
27、 item of equipment to verify that the ESRs of Directive 97/23/EC are satisfied, needs to be done. 2 Normative references The following referenced documents are indispensable for the application of this document.
