This European Standard shall be given the status of a national standard, either by publicatio
22、n of an identical text or by endorsement, at the latest by January 2018 and conflicting national standards shall be withdrawn at the latest by January 2018. 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
23、not be held responsible for identifying any or all such patent rights. This document supersedes EN 10028-4:2009. 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 Directive 2014/68/E
24、U. For relationship with Directive 2014/68/EU, see informative Annex ZA, which is an integral part of this document. A list of changes between this document and the previous version can be found in Annex B. According to the CEN-CENELEC Internal Regulations, the national standards organizations of th
25、e following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherl

BS EN 100284:2017EN 10028-4:2017 (E) 4 1 Scope This European Standard specifies requirements for flat products for pressure equipment made of nickel alloy steels as specifi
27、ed in Table 1. The requirements and definitions of EN 10028-1:2017 also apply. NOTE Once this European Standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to techn
28、ical data of 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 th
29、is specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the ed
30、ition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
