This European Standard shall be given the st
14、atus of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2008, and conflicting national standards shall be withdrawn at the latest by June 2008. This document supersedes EN 10028-7:2000. This European Standard has been prepared under a mandate
15、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 EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. The steel grades covered by this European
16、Standard have been selected from EN 10088-1. 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 temperature properties Part 3: Weldable fine grain
17、 steels, normalized Part 4: Nickel alloy steels with specified low temperature properties Part 5: Weldable fine grain steels, thermomechanically rolled Part 6: Weldable fine grain steels, quenched and tempered Part 7: Stainless steels NOTE The clauses marked by two points () contain information rela
18、ting 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 countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Repub- lic, Denmark, Eston
19、ia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 10028-7:2007 (E) 4 1 Scope This European Standard specifies requirements
20、 for flat products for pressure purposes made of stainless steels, including austenitic creep resisting steels, in thicknesses as indicated in Tables 7 to 10. The requirements of EN 10028-1 also apply. NOTE 1 The steel grades covered by this European Standard have been selected from EN 10088-1. NOTE
21、 2 Once this European Standard is published in the Official Journal of the European Union (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 (Part 1 and Part
22、7) 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 item of equipment to verify that the ESRs of the Pressure Equipment Directive are sat
23、isfied, needs to be done. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced docu- ment (including any amendments) applies
