This European Standard shall be given the status of a national standard, either by pu

24、blication of an identical text or by endorsement, at the latest by January 2018 and conflicting national standards shall be withdrawn at the latest by January 2018.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 CENELE

25、C shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 10028-2:2009. 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 2

26、014/68/EU. For relationship with Directive 2014/68/EU, see informative Annex ZA, which is an integral part of this document.

29、d alloy steels with elevated temperature properties as specified 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 R

30、equirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this European Standard (Part 1 and this Part 2 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 mater

31、ial standard against the design requirements of this 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

32、its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
