19、111 “Steel castings and forgings”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2017, and conflicting national standards shall be withdrawn at
20、 the latest by October 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 10222-3:1998. This document has been prepare
21、d under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 2014/68/EU. For relationship with EU Directive 2014/68/EU, see informative Annex ZA, which is an integral part of this document. EN 10222 consists of
22、 the following parts under the general title “Steel forgings for pressure purposes”: Part 1: General requirements Part 2: Ferritic and martensitic steels with specified elevated temperature properties Part 3: Nickel steels with specified low temperature properties Part 4: Weldable fine grain steels
23、with high proof strength Part 5: Martensitic, austenitic and austenitic-ferritic stainless steels. Annex A provides details about significant technical changes to EN 10222-3:1998. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are b
24、ound 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, Netherlands, Norway, Poland, Portu

EN 10222-3:2017 (E) DIN EN 10222-3:2017-06 4 1 Scope This European Standard specifies the technical delivery conditions of forgings for pressure purposes, made of nickel steels, for use at low temper
26、atures. NOTE Once this 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 technical data of materials in this standard and does not presume adequacy of the mat
27、erial 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 Directive 2014/68/EU are satisfied, needs to be done. The series EN 102221 to EN 10
28、2225 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5. General information on techn
29、ical delivery conditions is given in EN 10021. 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 edition cited applies. For undated references, the latest edition
30、of the referenced document (including any amendments) applies.
