This E
22、uropean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2016 and conflicting national standards shall be withdrawn at the latest by September 2016. Attention is drawn to the possibility that some of t
23、he elements of this 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 10305-4:2011. In comparison with the previous edition, the following technical changes have been made: a) Refe
24、rences were adapted; b) The options were renumbered in such a way that now throughout all parts the number of options are the same; c) Precision tubes will now be preferably ordered according to outer diameter and wall thickness; d) The drift expanding test is now beside the tensile test the second
25、test for the verification of the mechanical properties; e) Editorial updates. 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 Directive 2014/68/EU. For relationship with Directive
26、2014/68/EU, see informative Annex ZA, which is an integral part of this document.

DIN EN 10305-4:2016-08 EN 10305-4:2016 (E) 5 1 Scope This European Standard specifies the technical delivery conditions for seamless cold drawn steel tubes of circular cross section
30、used in hydraulic and pneumatic power systems. Tubes according to this document are characterized by having precisely defined tolerances on dimensions and a specified maximum surface roughness. The allowed pressure rates and upper temperatures are the responsibility of the customer in accordance wit
31、h the state of the art and in application of the safety coefficients specified in the applicable regulations, codes or standards. Concerning the lower temperature range applicability the impact energy requirements are given at 0 C. NOTE Once this standard is published in the Official Journal of the
32、European Union (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 material to a specific item of equipment. Consequently, the
33、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 the Pressure Equipment Directive are satisfied, needs to be done. 2 Normative references The following documents, in whole or in part, are n
