DIN EN 10272:2016-10 EN 10272:2016 (E) 5 Introduction The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of paten
26、ts concerning two steel grades given in 10.2, Annex A and Annex B. CEN takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured CEN that he/she is willing to negotiate licences either free of charge or under reasonable and non-di
27、scriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with CEN. Information may be obtained from: Outokumpu OYJ FI 02200 Espoo, Finland for steel grades 1.4162 and 1.4662 Attention is drawn to the possi
28、bility that some of the elements of this document may be the subject of patent rights other than those identified above. CEN shall not be held responsible for identifying any or all such patent rights. CEN and CENELEC maintain online lists of patents relevant to their standards. Users are encouraged
29、 to consult the lists for the most up to date information concerning patents (ftp:/ftp.cencenelec.eu/EN/IPR/Patents/IPRdeclaration.pdf). DIN EN 10272:2016-10 EN 10272:2016 (E) 6 1 Scope This European Standard specifies the technical delivery conditions for hot and cold formed stainless steel bars fo
30、r the construction of pressure equipment supplied in accordance with one of the process routes and surface finishes listed in Table 6. The general technical delivery conditions in EN 10021 also apply. NOTE Once this European Standard is published in the Official Journal of the European Union (OJEU)
31、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 and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of
32、 the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done. 2 Normative references The following documents, in whole or in part, are normatively re
