This European
18、Standard shall be given the status of a national standard, either 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of an identical text or by endorsement, at the latest by June 2014, and conflicting national standards shall be withdrawn at the latest by June 2014.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 th
19、is document may be the subject of patent rights. CEN and/or CENELEC 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
20、 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(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This Europ
21、ean Standard consists of the following parts, under the general 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 prop

25、This European Standard specifies the technical delivery conditions 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 (OJ
26、EU) under Directive 97/23/EC, presumption of conformity to 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 techn
27、ical 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 by the designer or manufacturer of the pressure equipment, taking also into account the subsequent
28、 manufacturing processes which may affect properties of the 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.
