22、EN 10216-4:2013 (E) DIN EN 10216-4:2014-03 3Foreword This document (EN 10216-4:2013) has been prepared by Technical Committee ECISS/TC 110 “Steel tubes and fittings for steel tubes”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, eit
23、her by publication of an identical text or by endorsement, at the latest by June 2014, and conflicting national standards shall be withdrawn at the latest by June 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CE
24、NELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 10216-4:2002. For the list of the most significant technical changes that have been made in this new edition, see Annex A. This document has been prepared under a mandate given to CEN by th
25、e European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard consists of the following parts, under the genera
26、l title “Seamless steel tubes for pressure purposes Technical delivery conditions“: Part 1 :Non-alloy steel tubes with specified room temperature properties; Part 2 :Non-alloy and alloy steel tubes with specified elevated temperature properties; Part 3 :Alloy fine grain steel tubes; Part 4: Non-allo
27、y and alloy steel tubes with specified low temperature properties (the present document); Part 5 :Stainless steel tubes. Another European Standard series covering tubes for pressure purposes is: EN 10217: Welded steel tubes for pressure purposes Technical delivery conditions. According to the CEN-CE
28、NELEC Internal Regulations, the national standards organizations 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, Greece, Hungary,
29、Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. EN 10216-4:2013 (E)DIN EN 10216-4:2014-03 41 Scope This European Standard specifies the technical delivery con
30、ditions in two test categories for seamless tubes of circular cross section, with specified low temperature properties, made of non-alloy and alloy steel. NOTE Once this standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, presumption of conformity to
31、the Essential Safety Requirements (ESR) of Directive 97/23/EC is 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 desi
32、gn requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which may affect properties of the
33、 base materials. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
