14、2017EN 102223:2017 (E)European forewordThis document (EN 102223:2017) has been prepared by Technical Committee ECISS/TC 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 id
15、entical text or by endorsement, at the latest by October 2017, and conflicting national standards shall be withdrawn at the latest by October 2017.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.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 f
16、or identifying any or all such patent rights.This document supersedes EN 102223:1998.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 EU Directive 2014/68/EU.For relationship with E
17、U Directive 2014/68/EU, see informative Annex ZA, which is an integral part of this document.EN 10222 consists of 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 temperatu
18、re properties Part 3: Nickel steels with specified low temperature properties Part 4: Weldable fine grain steels with high proof strength Part 5: Martensitic, austenitic and austenitic-ferritic stainless steels.Annex A provides details about significant technical changes to EN 102223:1998.According
19、to the CENCENELEC Internal Regulations, the national standards organisations of the 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, Greec

21、elivery conditions of forgings for pressure purposes, made of nickel steels, for use at low temperatures.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
22、 limited to technical data of materials in this standard 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 this specific item of equipment to verify tha
23、t the ESRs of Directive 2014/68/EU are satisfied, needs to be done. The series EN 102221 to EN 102225 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 d
24、epends on both the text in part 1 and the data in part 2, 3, 4 or 5.General information on technical delivery conditions is given in EN 10021.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
