This European 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of an identical text or by endorsement, at the latest by September 2016 and conflicting national standards shall be withdrawn at the latest by September 2016.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 the 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) References 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 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 2014/68/EU, see informative Annex ZA, which is an integral part of this document. EN 10305, Steel tubes for precision applications - Technical delivery conditions consists of the following parts: — Part 1: Seamless cold drawn tubes; — Part 2: Welded cold drawn tubes; — Part 3: Welded cold sized tubes; — Part 4: Seamless cold drawn tubes for hydraulic and pneumatic power systems; — Part 5: Welded cold sized square and rectangular tubes; — Part 6: Welded cold drawn tubes for hydraulic and pneumatic power systems. According to the CEN-CENELEC 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, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 10305-4:2016 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 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 with 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 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 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 normatively referenced in this document and are indispensable for its application.
