21、rd This document (EN 10028-5:2017) has been prepared by Technical Committee ECISS/TC 107 “Steels for pressure purposes”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at
22、the latest by January 2018 and conflicting national standards shall be withdrawn at the latest by January 2018.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 not be held responsible for identifying any o
23、r all such patent rights. This document supersedes EN 10028-5:2009. 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/EU. For relationship with Directive 2014/68/EU
24、, 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 the following countries are bound to implement
25、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, Netherlands, Norway, Poland, Portugal, Romania, Serb
26、ia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 100285:2017EN 10028-5:2017 (E) 4 1 Scope This European Standard specifies the requirements for flat products for pressure equipment made of weldable fine grain thermomechanically rolled steels as specified in Ta
27、ble 1. The steels are not suitable for hot forming. NOTE 1 At the time of publication of this European Standard, no sufficient data for the standardization of the elevated temperature properties of these steels was available. If their use at such temperatures is intended the conditions for this shou
28、ld be specially agreed between the interested parties. The requirements of EN 10028-1:2017 also apply. NOTE 2 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
29、/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 specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the
30、 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 its application. For dat
31、ed references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Additionally the relevant options
36、 of EN 10028-1:2017 apply. If the purchaser does not indicate a wish to implement any of these options at the time of enquiry and order, the products shall be supplied in accordance with the basic specification (see also EN 10028-1:2017): 1) providing data on suitable welding conditions (see 8.2.2);
37、 2) maximum carbon equivalent (see 8.3.3); 3) specification of a minimum impact energy of 40 J (see 8.4 and Table 5); 4) mid thickness test pieces for the impact test (see Clause 10). 7.3 Example for ordering 10 plates with nominal dimensions, thickness = 50 mm, width = 2 000 mm, length = 10 000 mm,
