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22、n of an identical text or by endorsement, at the latest by January 2018 and conflicting national standards shall be withdrawn at the latest by January 2018.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 10028-3:2009. 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 C. 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 100283:2017EN 10028-3:2017 (E) 4 1 Scope This European Standard specifies requirements for flat products for pressure equipment made of weldable fine grain steels as

27、specified in Table 1. NOTE 1 Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in accordance with EN ISO 643. The requirements and definitions of EN 10028-1:2017 also apply. NOTE 2 Once this European Standard is published in the EU Official Journal (OJEU

28、) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical 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 specif

29、ic 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 2014/68/EU are satisfied, needs to be done. 2 Normative references The following documents

30、, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

N), b) elevated temperature

34、quality (P.NH), c) low temperature quality (P.NL1) and d) special low temperature quality (P.NL2). 6.1.2 The grades P275NH to P355NL2 are alloy quality steels, the grades P275NL2 and the grades P420NH to P460NL2 are alloy special steels. 6.2 Designation See EN 10028-1:2017. 7 Information to be suppl

For steels with minimum yield strength 420 MPa, delayed cooling or additional tempering ma

42、y be necessary for small product thicknesses and in special cases. If such a treatment is performed, this shall be noted in the inspection document. 8.2.2 Normalizing may, at the discretion of the manufacturer, be replaced with normalizing rolling for all steel grades covered by this standard. In th

43、is case, additional tests on simulated normalized samples with an agreed frequency of testing may be agreed at the time of enquiry and order to verify that the specified properties are complied with. 8.2.3 If agreed at the time of enquiry and order, products covered by this document may also be deli
